Learning a new skill can sometimes be time-consuming, and learning to sail also means learning a new language with tons and tons of new words that, in the beginning, makes no sense at all.

Some of the words you will read about in this article stem from the early days of sailing. Some are only a decade old; in this article, I have tried to compile all the basic terminology that I believe a beginner needs if he or she wants to understand sailing and catamarans.

Feel free to use this article as a resource and come back to it when you want to look something up or just to learn more!

Main sections on a catamaran

  • Hulls; are what separates a cat from other sailboats, a catamaran has two hulls, a trimaran three, and a regular sailboat, aka monohull, has one. The hull is the part of the sailboat which makes it float and to where all other things are attached. The hulls are usually divided into sections, such as usable and non-usable area. An example of a usable area is the engine room.
  • Cockpit ; is from where the boat is maneuvered; it is to here that all halyards, sheets, etc. go. The cockpit contains navigation and steering equipment and is from where the sails, rudder, and engine are controlled.
  • Deck; is the top part(roof) of a catamaran covering the hulls and bridge deck. The deck is made hard enough to walk on. To the deck, attaches lifelines and other equipment.
  • Sugarscoops ; are the aftmost part that gets their name from their scoop-shaped appearance; this is where the deck/cockpit meets that water and usually encompasses a stair or ladder for easy access depending on the size of the boat.
  • Cabin; is basically any area on the inside of the boat that is protected from the weather and is made to offer the crew space to rest, eat, and hangout. Inside the cabin, you will find berths (beds), a galley (kitchen), and sometimes specialized areas for repairs or storage.
  • Bridgedeck; connects the two hulls; the inside is the cabin, the top part is the deck, and the entire unit is called the bridge deck. Bridge deck clearance, the bridge deck’s height above the water, is an important factor on a catamaran since a too small clearance will create excess noise and vibrations and fatigue not only the crew but also the boat.

Main areas on a catamaran

Bow (front).

Nothing complicated here; the bow is just a nautical term for the foremost part of your boat. This is where the waves and the sea first meet the hull and depending on the type of boat, the bow(s) can be shaped differently.

Center (Middle)

The part between the bow and the stern is rarely called the center part( middle) of a boat; more common is to speak about the specific area situated within the middle part of the vessel, such as the cabin or the mast.

  • Cockpit; as mentioned above, here you will (usually) find everything that you need to maneuver and navigate the boat, such as a compass, GPS, sheets, steering wheel, and throttles for the engines. Some boats may not be set up this way and require you to move around the boat to access certain controls.

Cabin (inside of the boat)

The boat’s interior is where you will find everything that is made for the crew’s enjoyment; it is a place to eat, sleep, rest up, and hide away from nasty weather.

  • Berths; is a bed; sailors need to sleep too!
  • Galley ; is another name for kitchen, usually set up in a very primitive way with a gas stove on a stabilized platform to ensure your food won’t get tossed around.
  • Navstation; or navigation station, is a place, usually with a table, chair, and equipment for planning and logging a journey.

Stern (Back)

Stern is the name for the rearmost part of the boat; there is no clear definition as to where the stern stops and other parts begin, so it is something that the crew will have to figure out on their own through good communication.

Communicating directions on a sailboat

Not only will you have to know the different names of different areas on the boat, but it will also be essential to communicate clearly in what direction something is happening, for example, in a situation where you, the captain, want the crew to observe in a specific direction or pick up a piece of gear somewhere on the boat.

Communication on a sailboat is vital when you want to sail safely and efficiently; here, I have listed the words or phrases used to communicate a direction.

  • Forward; easy as it sounds, it is the same direction as where the bows are pointing. When giving directions towards or beyond the bow, you will use the word “forward” for example; the fender is located forward of the mast.
  • Aft ; is the behind the boat. When you are giving directions towards the stern, you will use the word “aft”; for example, the cockpit is located aft of the mast.
  • Port ; this will be your left side. Fun fact, in the good old days, you would always dock with the port on your left side; hence port is the left side. If you ever forget which one is which, “port” has 4 letters and so has the word”left”!
  • Starboard ; is your right side!

Types of sails

Sails come in very different shapes and sizes and are a science in itself; in this article, I will focus on the mainsail and three common types of staysail.

  • Mainsail; is, per definition, the sail attached to the mast; its sideways movements are controlled by the boom. When the mainsail is triangular in shape, as on most modern sailboats, it is called a Bermuda rig. Most mainsail uses something called battens.
  • Staysail; mainly comes in two versions, a staysail that does not overlap the mainsail is called a jib. A staysail that is larger and thus overlaps the mainsail is called a genoa.
  • Spinnaker ; is a big balloon-like sail that replaces the jib when sailing downwind.

Parts of a sail

  • Luff; the front part of the sail, is connected to the mast through a rail system which makes it possible to hoist or reef.
  • Leech; the back part of the sail.
  • Foot; the bottom part that reaches from the clew to the tack.
  • Clew; back bottom corner.
  • Tack; is the front bottom corner (remember “tacking”?).
  • Head; is the top triangle of the sail and this is where the mainsail halyard attaches.
  • Battens; are pieces of flexible material sewn into the mainsail to increase its aerodynamic shape. Battens can be full length or partial length.

Standing rigging

Everything that keeps the sails and mast upright are parts of the standing rigging; it is comprised of wires, cables, and lightweight metal structures.

  • Forestay; usually a metal wire running from the top of the mast to the bow, is sometimes combined with an inner forestay that connects to the mast at a lower point. If the forestay attaches to the top of the mast, the setup is called a masthead rig; if it attaches lower, it is called a fractional rig.
  • Backstay ; same as the forestay but attaches to the stern; most catamarans do not employ a backstay system but instead moves the side stays aft.
  • Shroud ; much like the forestay but stabilizes the mast sideways and runs from the top to the port or starboard side. Spreaders are used to change the angle of the wire against the mast and better support the mast.
  • Sidestay ; connects to the mast below the shrouds and is not pushed outwards with spreaders. On a catamaran, these attach aft of the mast to eliminate the need for a backstay; this makes it possible for a fully battened mainsail with a large roach.
  • Jumpers; are used on a fractional rig with diamond shrouds to add structural integrity to the mast without adding excess weight.
  • Bowsprit; is a pole amidship at the bow that allows for separation of the tacks (foremost, lower part of the sail) for increasing sail efficiency when using two headsails.

Other stabilizing parts

  • Spreaders; act to lessen the angle between the shrouds and the mast; a wider angle will result in forces acting sideways (stabilizing) instead of up and down (bending). This increases stability and decreases the risk of unwanted bending of the mast.

Running rigging

The running rigging on a catamaran is any piece of equipment used to control the shape of the sails, including what is needed to raise them.

  • Sheet; are the ropes (or wire, cables, etc.) that connect to the clew of a sail; on a catamaran, it connects to the staysail (genoa or jib, depending on the shape).
  • Mainsheet ; is the rope that makes it possible to change the mainsail’s angle; the mainsail can only move in a port to starboard direction(right and left) and not up and down.
  • Staysail sheet ; is called after whatever type of sail it is connected to, i.e., jib sheet or genoa sheet. Worth notice is that since the staysail operates on both sides of the catamaran (depending on if your tacking or gybing), it is connected with two ropes, one for the port side and one for the starboard side.
  • Halyards ; are the ropes that connect to the top of a sail and make hoisting (or raising) possible. Halyards have different names depending on what sail they are raising, such as Mainsail halyard or jib halyard. Not to be confused with sheets that act upon the sail once they are already hoisted. If the staysail is using a roller furling, then “hosting” is done differently.
  • Furling line; is used together with a roller furling and makes it possible to spool up the sail on the forestay instead of raising and lowering. This makes for a faster and easier way to reduce sail area.
  • Reefing lines; reefing is when you lower parts of your sail to reduce the sail area and reduce the boat’s power and speed; reefing lines are put through holes in the mainsail and attach to the boom.
  • Boom vang; is connected between the boom and deck; it is used to change the mainsail’s shape by pulling downward on the boom. (not very common on Catamarans)

In this category, we will look at the hulls and some of the vital parts that attach to them under the waterline.

  • Hulls; differ in their shapes depending on the boat’s purpose, a racing cat would have narrower hulls to reduce drag, and a cruising cat wider hulls to encompass more storage.
  • Rudder; is what changes the direction of the boat. When water passes around the rudders(two on a catamaran), it creates a “pushing force” that makes the boat turn. The rudder is connected to a steering wheel or a tiller at the cockpit through chains and linkage.
  • Centerboard and daggerboards ; are sorts of keels that can be raised or lowered to attain certain sailing characteristics. When the keel is up, drag is lower, and so is the draft (how deep the boat sticks in the water). A small draft makes it possible to travel in very shallow waters. The difference between a daggerboard and a centerboard is that a centerboard swivels into place, and a daggerboard is pulled straight up.
  • Mini-keel; is just what it sounds like; it is a keel but very small (a few inches deep) and has no ballast.
  • Crossbeam ; is a multihull-only feature and keeps the two hulls from moving in relation to each other. If the crossbeam is damaged or nonexistent, the bridge deck is the only thing that keeps the hulls in place. This will increase wear and sooner or later lead to cracks, or even worse, separation of hull and bridge deck.

Most catamarans have two engines, one on each hull aft the stern; usually, they are internal with only the propeller in the water. The other option, which is cheaper and most often found on smaller boats, is to have one outboard engine placed amidship (middle).

  • Inboard ; engines are situated in a compartment inside the boat at the stern. On an inboard engine, the propeller and the shaft are the only parts outside the hull. Sometimes the prop shaft (propeller shaft) is replaced by a sail drive.
  • Outboard ; is a standalone engine usually mounted on the bridge deck amidship(if only one is used) or mounted at the sterns when used in pairs. They are linked together with pushing rods and wires so it can be manipulated from the cockpit.
  • Saildrive ; is a type of gearbox that is quieter and vibrates less than a regular propeller and shaft setup.
  • Propeller and shaft; are the most common and cheapest way to propel your boat. It is basically just a watertight axel that sticks out of the hull, and at the end of it, you’ll find the propeller.

There are so many pieces of gear aboard a catamaran that an all-encompassing article would probably fill up the entire internet. Below I have listed the most common equipment that you will most likely encounter on any sailboat.

  • Winches; makes handling lines and ropes much easier. Instead of pulling them with your bare hands, you loop them around your winch and use the handle to crank. Winches come in mechanical style or electrical style.
  • Anchors ; is basically just a big hook made to stick to the bottom of the sea. Anchors have different shapes and weights depending not only on the seabed but also on the boat’s weight and size.
  • Navigation ; compass, GPS, and maps are all vital pieces of equipment making your trip safe.
  • Cleats ; is any equipment that is made to fasten a rope. Cleats come in different configurations; jam, cam, rope clutch, or the most common horn cleat.
  • Block ; is a device that can be used in pairs as a pulley (to reduce the force needed to lift something) or on its own to reduce the friction of a rope when the rope can not be drawn in a straight line.

Understanding Catamarans

Design Characteristics

Catamarans are known for their unique design, which features two parallel hulls connected by a deck. This design provides several advantages over traditional monohull boats, such as stability and speed.

With their wide beam, catamarans have a reduced risk of capsizing and can access shallow waters due to their shallow drafts 1 .

One of the notable aspects of a catamaran is its twin hulls, which offer increased living space and comfort compared to a monohull. Additionally, catamarans are often favored by recreational and competitive sailors for their excellent maneuverability 2 .

The materials used for constructing catamarans range from wood to fiberglass, and even aluminum for high-performance vessels. Aluminum catamarans are known for their strength, lightweight structure, and resistance to corrosion 3 .

Hulls and Construction

The hulls in a catamaran are crucial to its stability and performance. These hulls help distribute the weight evenly across the water surface, minimizing drag and allowing for smoother sailing.

In general, the hulls can be categorized into two types:

  • Symmetrical Hulls : The hull shape is similar on both sides, which enhances balance and stability in various sailing conditions.
  • Asymmetrical Hulls : One side of the hull is designed differently than the other, which can be advantageous when sailing upwind.

The construction materials used in building catamaran hulls also play a vital role in the boat's performance and durability. Common materials include:

  • Fiberglass : A popular choice due to its lightweight, strength, and ease of maintenance.
  • Wood : Traditional material that offers a classic look, but requires more maintenance than fiberglass or aluminum.
  • Aluminum : Lightweight and strong, aluminum is an excellent choice for high-performance catamarans 4 .

Multihulls vs Monohulls

There's often a debate between the benefits of multihull boats, such as catamarans or trimarans, and monohull boats. Here are some key differences between the two:

  • Stability : Due to their wide beam and reduced heeling, catamarans offer improved stability compared to monohulls. This makes them an attractive option for those who want to avoid seasickness or feel more comfortable on the water 5 .
  • Speed : Multihull boats are known for their speed, which results from their ability to minimize drag and maintain a level sail.
  • Living Space : Catamarans and other multihulls generally have more living space, as both the hulls and the connecting deck can be utilized for accommodation and storage.
  • Maneuverability : While monohulls are known for their agility and ability to point close to the wind, catamarans can still offer exceptional maneuverability when properly sailed 6 .

Performance and Handling

Speed and Efficiency

Power catamarans have gained popularity for offering a unique combination of speed, efficiency, and stability. Their dual-hull design allows for less water resistance, which directly translates to higher speeds and better fuel efficiency compared to traditional monohull boats.

In addition, the wide beam provided by the two hulls ensures a stable ride even at higher speeds. This makes power catamarans ideal for cruising, fishing, and watersports ( Boating Beast ).

Sailing Dynamics

When it comes to sailing catamarans , the performance is affected by factors such as keel, rudders, mast, and sails.

Their wide beam and dual-hull design provide inherent stability and reduced heeling effect, making them less likely to capsize compared to monohulls.

I should also note that catamarans have a shallow draft, which gives them the ability to access shallow waters that may be off-limits to other boats ( Navigating the Waters ).

In my experience, the lighter weight of a catamaran and its aerodynamic design can contribute to remarkable sailing performance under different wind conditions.

The larger sail area relative to hull weight allows them to harness more wind power, further enhancing their speed and agility on the water.

Maneuvering and Docking

Maneuvering and docking a power catamaran involves understanding its unique handling characteristics.

The presence of two engines in separate hulls allows for more precise control in confined spaces such as marinas.

The maneuverability of these boats is typically improved by the use of dual rudders that are located close to each powered hull for efficient steering ( BoatUS ).

When docking under power, I find it helpful to carefully assess the wind and current conditions beforehand.

This is because catamarans can be more sensitive to windage due to their larger surface area above the waterline.

By understanding how these forces may affect the boat, I can make adjustments to my approach and successfully dock the catamaran without any incidents.

Safety and Comfort on Board

Safety Features

Safety is a top priority when sailing any type of vessel, including catamarans. A well-built catamaran offers several features aimed at ensuring the safety of those onboard.

First, catamarans have inherent stability due to their wide beam and twin hull design . This makes them less prone to capsizing than monohull boats. This stability allows me to confidently navigate various water conditions .

In addition to stability, catamarans are designed with positive buoyancy, making them almost unsinkable . Of course, safety equipment such as lifejackets, flares, and first aid kits should always be onboard and well-maintained.

Furthermore, you should also stay updated on weather conditions, avoid sailing in high-risk areas, and learn your boat's safe sail limits.

Living Spaces and Comfort

When it comes to living spaces, I value comfort and practicality as essential features for my time on the water. Catamarans offer a unique advantage in this regard, as their dual hulls create spacious living areas.

Most catamarans are designed with separate cabins in each hull, allowing for privacy and comfort when sleeping. Additionally, these boats typically feature shallow drafts , which means I can access shallow waters and anchor close to shore.

The main living area, or salon, is situated on the bridge deck between the hulls. It usually includes a seating area, a dining table, and a galley (kitchen). Large windows provide ample natural light and panoramic views, making the space feel open and bright. Some catamarans even have the option for an additional living area on the upper deck where you can enjoy the sun and breeze.

One aspect of catamaran living I truly appreciate is the ample storage available. Each cabin typically has built-in storage spaces for clothes, gear, and personal items. There are also designated areas for equipment such as spare sails, tools, and water toys. This makes it easy for me to keep my belongings organized and make the most of my time on the water.

Maintaining a Catamaran

Routine Maintenance

In order to keep my catamaran in the best possible shape, I make sure to perform routine maintenance tasks. These tasks are essential to extend the life of the components and ensure smooth sailing:

  • Cleaning : Regularly cleaning the deck, hulls, and sails prevents buildup of dirt, algae, and other debris that could affect performance.
  • Inspection : Periodically inspecting my catamaran allows me to detect any potential issues before they become significant problems. I pay close attention to the rigging, sails, and lines on my boat.
  • Lubrication : Keeping all moving parts lubricated is vital to prevent friction and wear on components such as winches and pulleys.
  • Antifouling : Applying antifouling paint to the hulls of my catamaran helps prevent the growth of marine organisms that can damage the boat and reduce its speed. Make sure to do this at least once a year.

Dealing with Wear and Tear

Despite my best efforts to keep my catamaran well-maintained, wear and tear is inevitable. Here's how I deal with common issues that could arise from regular use:

  • Repairs : When I notice signs of wear on sails, lines, or rigging components, I make it a priority to repair or replace them promptly. Neglecting these issues can lead to more significant problems and affect the boat's performance.
  • Hull maintenance : If I find dents, scratches, or stiff rudders on my catamaran's hulls, I address them immediately. Repairing any damage not only ensures smooth sailing but also prevents further issues from developing.
  • Sail care : Over time, my sails can become stretched, torn, or damaged due to exposure to sun, wind, and saltwater. Regularly inspecting them for signs of wear and making any necessary repairs or replacements helps maintain optimal performance.
  • Rust and corrosion prevention : Since my catamaran is made of various metal components, I need to protect them from rust and corrosion. I routinely check for signs of corrosion and apply anti-corrosive treatments when needed.

Catamaran Brands and Models

High-Performance Models

In recent years, there has been a growing interest in high-performance catamarans. I have seen a variety of brands and models that have impressed me with their performance capabilities. One notable brand is Fountaine Pajot , which has a long history of producing a range of sailing catamarans and power catamarans. Some of their popular models include the Tanna 47 and the Bali 4.4 .

Another high-performance catamaran I've come across is the Leopard 40 . Known for their speed and exceptional handling in various conditions, the Leopard brand started with sailing catamarans and has since expanded to include power catamarans. Their models range from 40 to 53 feet long, offering both power and luxury for those looking for a thrilling experience on the water.

Cruising Catamarans

When it comes to cruising catamarans, the Lagoon brand is synonymous with luxury and comfort. With a range of sailing catamarans from 40 to 70 feet long, Lagoon offers spacious catamarans for extended bluewater cruising. Their 60- and 70-foot power catamarans are equally impressive, providing ample living space and smooth sailing experiences.

I've also found the Aquila 42 PC to be a remarkable cruising catamaran. With a focus on design and innovation, Aquila has produced catamarans perfect for exploring the open sea with friends and family. Their spacious, stable designs allow for a more enjoyable and serene journey, ensuring you arrive at your destination comfortably.

The Catamaran Lifestyle

Anchoring and Cruising

I find catamarans to be a fantastic choice for cruising and anchoring , which is a critical part of living the catamaran lifestyle . Catamarans have several advantages when it comes to anchoring and cruising, such as:

  • Stability : Due to their wide beam and twin hulls, catamarans remain stable during anchoring, which reduces the risk of seasickness.
  • Shallow draft : Thanks to their shallow draft , catamarans can anchor close to shore, enabling better access to protected coves and more beautiful beaches.
  • Speed : Despite their large size for cruising vessels , catamarans are generally faster than monohulls. This is a result of their slim hulls and reduced water resistance.

When it comes to anchoring, catamarans can make use of their shallow draft to anchor in locations that other boats cannot. This allows for a greater range of cruising spots, which makes the overall experience much more enjoyable and unique.

Living on a Catamaran Full-time

For many catamaran enthusiasts, the dream of living full-time on a catamaran is entirely possible. While not without challenges, there are several factors that make living aboard a catamaran an enjoyable experience:

  • Spacious living areas : Catamarans generally have more living area compared to monohulls, providing ample space for the whole crew.
  • Privacy : The separate hulls allow for private cabins, ensuring that everyone on board has their space.
  • Stability : As mentioned earlier, catamarans are stable vessels, making living on them more comfortable than monohulls.

Choosing Your Catamaran

Comparing Models and Features

When I start to look for the perfect catamaran, the first thing I focus on is comparing various models and features .

I determine the key factors that are essential for my needs, such as size, passenger comfort, and performance. By doing so, I can identify which catamaran models are most suitable for me.

For example, if I plan to sail with a large group, I would look for a catamaran that offers ample space both inside and out.

To help me with my comparisons, I usually create a table or list of the different models and their features:

ModelSizeComfortPerformance
A40ftSpaciousHigh
B35ftAverageAverage
C45ftLuxuryHigh

This visual aid makes it easier for me to sort the options and prioritize my considerations, such as price, yacht type, and brand.

New vs. Second-Hand

Another critical aspect of choosing a catamaran is deciding between a new or second-hand boat.

Both options have their pros and cons, and ultimately it depends on my preferences and budget.

If I can afford a new catamaran, I get the advantage of the latest design , features, and technology. Plus, I typically receive better warranty coverage and support from the manufacturer.

However, new catamarans are more expensive and can have long wait times due to high demand.

On the other hand, purchasing a second-hand catamaran can save me a significant amount of money, and I might find a high-quality boat with low mileage or well-maintained by the previous owner.

However, this option carries more risks, as I need to be knowledgeable about potential maintenance issues and conduct a thorough inspection before purchase.

Learning Resources

Books and Manuals

When it comes to learning about catamarans, there are plenty of books and manuals available.

One of the highly recommended books is Multihull Voyaging by Thomas Firth Jones. This book provides a comprehensive understanding of multihulls, including catamarans, and is an essential guide for any beginner sailor.

Another great book to check out is Catamarans: The Complete Guide for Cruising Sailors by Gregor Tarjan.

With a foreword by Charles K. Chiodi, publisher of Multihulls Magazine, this book covers all aspects of cruising catamarans. It includes detailed information on design, construction, and maintenance, as well as tips and tricks for sailing a catamaran.

Here are a few more books that I find valuable:

  • The Catamaran Book by Tim Bartlett, an excellent resource for both beginners and experienced sailors
  • Catamaran Sailing: From Start to Finish by Phil Berman and Lenny Rudow, a comprehensive guide to both catamaran racing and cruising

The Illustrated Guide To Boat Hull Types (11 Examples)

I didn't understand anything about boat hull types. So I've researched what hulls I need for different conditions. Here's a complete list of the most common hulls.

What are the different boat hull types? There are three boat hull categories: displacement hulls, which displace water when moving; planing hulls, which create lift at high speeds; and semi-displacement hulls, which displace water and generate lift at low speeds. The most common hull types are round-bottomed, flat-bottomed, multi, V-shaped, and pontoon hulls.

But that's all pretty abstract if you ask me, so below I'll give a simple overview of what it all means. After that, I'll give a list with pictures of all the different designs.

A Simple Overview of Boat Hull Types

Your boat hull will be the biggest factor in how your boat handles or sails, how wet it is, how bumpy - absolutely everything is determined by the hull shape. So it's important to understand what different hulls will do for you, and what each hull is best for. First, let's slice it up into rough categories.

Roughly, you can divide boat hulls into three categories:

  • Displacement hulls - Lie inside the water and push it away when they move
  • Planing hulls - Lie on top of the water and don't push it away
  • Semi-displacement hulls - Lie inside the water and push it away, but can generate lift

Everything I'll be mentioning below is one of those three, or something in between.

There are five common boat hull types:

  • Round-bottomed hulls - handle well in rough water: sailboats
  • Flat-bottomed hulls - very stable for calm inland waters: fishing boats
  • Multihulls - very stable and buoyant: catamarans
  • V-Shaped Hulls - fast and comfortable in chop: powerboats
  • Pontoon hulls - fast and stable: pontoon boats

And then there's everything in-between.

Here's a quick and handy overview of the different hull types

catamaran hull name

In each category, we find different designs and styles that have different characteristics. There isn't a real clear distinction between categories and styles: there are semi-displacement hulls and so on. So I thought the best way to learn you the different hull types is by simply creating a list with lots of pictures, instead of getting all theoretical about it.

So below I've listed all the different hull styles I could possibly think of, mention what category and type it is, the pros and cons of each one, and give you examples and illustrations for each one.

On this page:

Displacement hulls, round-bottom hull, catamaran hull, trimaran hull, planing hulls, flat-bottom hull, deep v-hull, modified-v hull, stepped hull, pontoon hull, semi-displacement hulls.

Examples: Sailboats, trawlers, fishing boats

catamaran hull name

Displacement hulls displace water when moving. These hulls lie in the water, instead of on top of it. The amount of water they displace is equal to the boat's weight. Displacement hulls handle way better in rough waters than flat-bottom hulls. That's why most cruisers have some sort of displacement hulls. There are actually all kinds, shapes, and forms of the displacement hull design, which we'll go over later.

The most important thing to understand about the displacement hull, is that it operates on buoyancy. This means that most of the boat's weight is supported by its capacity to float . Planing hulls, on the other hand, operate on lift instead, but we'll dive into that later.

Sailboats typically have displacement hulls, but also fishing boats, trawlers and crabbers. All in all, it's used for each boat that needs to handle well in rough conditions.

Learn everything there is to know about displacement hulls in this article . It lists all the pros and cons and really goes into detail on the nitty-gritty about how displacement hulls actually work .

catamaran hull name

But they are also slower than flat and planing hulls because the boat creates more resistance when moving. It has to push the water aside. In fact, this type of hull has a built-in upper-speed limit.

This upper-speed limit is called maximum hull speed . It means that the length of a displacement hull directly determines the maximum speed. It can't go faster, because the water-resistance increases with the boat's speed. To learn everything about calculating maximum hull speed , please check out my previous article here.

catamaran hull name

A round-bottomed hull is a type of displacement hull - it lies in the water and has to power through it. But since it's rounded, it creates little resistance and is effortless to move through the water. It's a very smooth ride and typical for any sailboat that sort of glides through the waves. In contrast, powerboats really have to eat their way through the water.

Examples: Canoes, sailboats

They are also one of the least stable. Since the bottom is rounded, your boat or canoe will rock plenty when boarding or moving around. They are also easy to capsize. That's why pro canoers learn to do a 360 in their canoes. I've never did a roll myself but came close enough a couple of times.

catamaran hull name

Almost all sailboats use a round bilge as well. This provides it its buoyancy and makes sure it handles well in waves. But since a rounded bilge is easy to capsize, a lot of sailboats have some sort of keel, which stabilizes the roll.

Nearly all ocean-going vessels use some sort of displacement hull, and the round bottom is the most common one. But our next guest is very popular as well.

The catamaran is similar to the pontoon hull (read on to learn more on that one), but it is a displacement multihull instead of a planing one. So it has two hulls, that lie inside the water and displace it. Like the pontoon, you will have to try really hard to capsize this design (and it won't work).

Examples: well, catamaran sailboats. But also this cool catamaran trawler:

catamaran hull name

Catamarans are extremely popular ocean cruisers. Their biggest pro is their extreme stability and buoyancy. And they have a very shallow draft for a displacement hull, making them very popular for sailing reefs and shallow waters, like the Caribbean.

Some cons for the catamaran are less agile than monohulls. They have a large turning radius, making them less maneuverable. Also, expect to pay high marina fees with this one.

Speaking of marina fees, our next one can go either way.

I think trimarans are incredibly cool, and especially the second type.

There are two types of trimarans:

  • a catamaran with three hulls instead of two,
  • or a displacement monohull with two floaters.

The first has the same characteristics as the catamaran: it's a displacement multihull, but now with three hulls:

catamaran hull name

The second can be a regular displacement monohull, with two pontoon-type floaters that provide extra buoyancy, making the total thing a hybrid between pontoon and displacement:

catamaran hull name

This last one has all the pros of a catamaran in terms of stability, but: you can simply wheel in those floaters whenever you head for port. That saves you a lot of money. And you can trailer her! Imagine that, a towing a trimaran home.

So those were the most common displacement hulls, aka what lives in the water. Let's move on to the planing hulls, aka what lives on the water.

catamaran hull name

Planing hulls are a hybrid between the flat-bottom and displacement hulls. Planing hulls displace water at low speeds , but create lift at higher speeds . The shape of their hull + speed lifts them out of the water, making them glide on top of the water. Most powerboats look like flat-bottom boats but use a shallow V-shape that helps the boat to handle better at higher speeds.

Examples: Water sports boat, powerboats

The most important thing to understand about planing hulls is that they operate mainly on lift instead of buoyancy. This means the weight of the boat is mainly supported by dynamic forces 1 . With the right amount of power, this design generates lift, which results in less resistance. This is why they are a lot faster than boats with displacement hulls, but also a lot rougher, even with mild chop.

A lot of powerboats use some sort of planing hull. Again, there are many designs and variations on the planing hull, and I'll try to mention as many as I can below.

Because the wedge of the hull runs into the water, it is much easier to handle at high speeds. At lower speeds, it is able to keep its course, even with a bit of wind. However, whenever the boat starts planing, it is prone to wind gusts, since the wedge shape no longer stabilizes the boat.

The flatter the hull, the faster it will go, but also the more poorly it will handle. Other powerboats use deep V-hulls, which I'll discuss below. But first, let's take a look at the flattest hulls you'll ever see.

A flat-bottom hull lies on top of the water and doesn't displace water (okay, very little) as it moves. Since there is no displacement, there is also little to no friction when moving. This makes it potentially fast, but it handles pretty poorly. It is one of the most stable hull design.

Examples: rowboats, (old) high-performance powerboats, small skiffs, small fishing boats, tug boats

catamaran hull name

They aren't just incredibly stable, they're also very practical. Because the bottom is practically flat, they maximize boat surface. But they are also extremely choppy in rough weather and waves. They will handle very poorly with stiff winds, as the wind can simply catch them and blow them across the water surface. That's why this design is almost exclusively used for calm, small, inland waters.

This type of hull operates mainly on buoyancy , like the displacement hull, but it doesn't require the same amount of power to propel, which is why it's faster.

Because of the uncomfortable ride, not a lot of boats use a perfectly flat bottom. Most boats nowadays use some sort of v-hull or hybrid design, like a semi-displacement hull; especially larger boats. So not a lot of boats have a real flat bottom. However, we do call a lot of boats flat-bottomed. How come?

catamaran hull name

There are two types of hulls we call flat-bottoms:

  • Of course boats with an actual flat bottom
  • Boats with almost no deadrise
What is the hull's deadrise? The deadrise is the angle of the front of the hull to the horizontal waterline.

As you can see, the green sailing dinghy in the picture above has a deadrise that's barely noticeable.

Let's move on to other variations of the planing hull. One of the most popular hull design for modern-day powerboats is the Deep Vee hull. And that's as cool as it sounds.

catamaran hull name

This is a type of planing hull that combines the best of both worlds.

These types of hulls are very popular on modern-day powerboats, and no wonder. With a V-shape that runs from bow to stern, deep into the water, you can handle this boat even in offshore conditions. It handles a lot better than flat-bottomed hulls, while it's at the same time extremely fast.

Examples: Most modern powerboats.

The Deep V-shape acts as a tiny keel of sorts, stabilizing the boat and making it more reliable and maneuverable. The rest of the hull acts as a planing hull, giving the boat its fast edge. Even at high speeds, the Deep V will cut into the water, making it more handleable.

The deep-V design is just one of many variants on the V-hull. Below we'll talk over another, the modified V hull.

catamaran hull name

The modified V hull is the ultimate crossover of all planing hull types. It's a mix of the flat-bottom and Deep V hull. It is one of the most popular hull designs for small motorboats. It's flat in the back and then runs into a narrow V-shape to the front. The flat back makes it more stable, and adds a little speed, while the V-shape front ensures good handling.

It is, in short, kind of the compromise-family-sedan of boat hulls. It's the fastest design that's also stable, that's also safe, and that also handles well. But it's not the best in any of those things.

Most powerboats you've seen will have some sort of Vee or Modified-V hull.

Stepped hulls are used on high-performance powerboats. It's a type of planing hull that reduces the hull surface by adding steps, or indents in the hull below the waterline. It looks something like this:

It is said to work extremely well at high speed (60 knots and up) and adds up to 10 knots to your top speed.

On to our next design. There are also planing multihulls, and they might even look like catamarans to you. Meet the pontoon hull.

catamaran hull name

Pontoon hulls float on top of the water using pontoons or floaters that create lift. It's a type of planing multihull that doesn't lie in the water, so it doesn't displace a lot of water. They don't really handle well. As with any multihull, they aren't agile - they're not great at maneuvering. They also have a very large turning radius. But they are extremely stable: there's no chance you'll capsize this.

Examples: Cruisers, modern trawlers, motor yachts, Maine lobster boats

catamaran hull name

Semi-displacement hulls are smack bang in the center of planning and displacement hulls. They are a bit better for speed than displacement hulls are. They are a bit better for handling rough waters than planing hulls are. This makes them very versatile.

catamaran hull name

You can see these a bit like being 'half-planing' hulls. These hulls are designed to plane at lower speeds than normal planing hulls - somewhere in the range of 15 - 20 knots, depending on the length of the boat. It also requires less power. When the hull lifts, it reduces drag (water resistance), making it faster and more efficient.

Semi-displacement hulls are perfect for boats that need to be steady and seaworthy but fast at the same time.

Step-by-Step Breakdown: Unraveling the Mysteries behind Catamaran Anatomy

Catamarans have become increasingly popular in recent years, mainly due to their unmatched stability and impressive speed capabilities. But have you ever wondered what lies beneath the sleek exterior of these remarkable vessels? In this blog post, we will delve into the intricate details of catamaran anatomy, providing you with a comprehensive understanding of how these boats are constructed and why they excel on the water.

1. The Hulls: The Foundation of Stability At the core of every catamaran lies its hulls – two parallel structures that run alongside each other. Unlike traditional monohull boats that feature a single hull, catamarans distribute their buoyancy across two hulls, offering superior stability even in rough waters. These hulls are typically made from fiberglass or aluminum and are designed to cut through waves effortlessly, minimizing resistance and maximizing speed.

2. Bridging the Gap: The Trampoline One striking feature present in many catamarans is the trampoline located between the two hulls. This sturdy mesh-like material serves various purposes. Firstly, it provides an additional platform for sunbathing or relaxing while underway. Secondly, it acts as a safety net by preventing crew members or passengers from falling into the ocean should any unexpected jolts occur during navigation .

3. Connecting Hulls: The Crossbeams In order to maintain structural integrity and connect both hulls securely, catamarans utilize crossbeams that stretch between them. These crossbeams play a vital role in sharing weight distribution evenly across both sides, ensuring stability and balance at all times.

4. Above Deck: Central Cockpit and Living Space Moving upwards onto the deck area, you’ll discover a central cockpit where most controls and steering mechanisms are located. This strategic placement allows for optimum visibility and easy maneuverability while sailing. Additionally, catamarans often feature large living spaces, including saloons and cabins that provide ample room for socializing, dining, and sleeping. Their spaciousness is a significant factor contributing to their growing popularity among cruising enthusiasts.

5. The Power of Sails: Rigging and Sail Plan Catamarans rely on sails for propulsion, utilizing a complex system of rigging to hoist and control them effectively. A unique feature of catamarans is the absence of a single mast; instead, they employ multiple masts strategically positioned between the hulls. This configuration optimizes sail area while reducing heeling (when a boat tips sideways due to windy conditions), resulting in smoother sailing experiences even during stronger winds.

6. Additional Features: Daggerboards or Foils To enhance performance further, some catamarans are equipped with daggerboards or foils – retractable appendages located beneath each hull. These boards reduce lateral slippage by providing lift, improving upwind capability and enhancing overall speed. As technology advances, advanced hydrofoil systems have also been introduced in certain catamaran models, allowing these boats to glide above the water ‘s surface entirely.

By unraveling the mysteries behind catamaran anatomy step-by-step, it becomes evident why these vessels are highly sought after by both leisure sailors and competitive racers alike. From their stable hull design to innovative features such as trampolines and foils – every element plays its part in creating an exceptional sailing experience that combines comfort, speed, and versatility.

Mastering the Parts of a Catamaran: A Beginner’s Guide for Sailing Enthusiasts

Are you a sailing enthusiast who is fascinated by the sleek and efficient design of catamarans? If so, then you’ve come to the right place! In this comprehensive beginner’s guide, we will delve into the key components of a catamaran and unlock the secrets to mastering its various parts. So grab your sailor’s hat and get ready to embark on an exciting journey through the intricate world of catamaran sailing!

The first component that sets a catamaran apart from other sailboats is its dual-hulled structure. Unlike traditional monohull sailboats, which have only one hull, catamarans feature two parallel hulls connected by a deck or bridge. This unique design grants them exceptional stability, speed, and even more interior space for amenities such as cabins and lounging areas.

Now let’s move onto a crucial part of any sailboat – the rigging . The rigging system on a catamaran consists of numerous elements that work harmoniously to control and manipulate the sails . Firstly, there are the masts: tall vertical structures that support the sails. Catamarans typically have two masts placed towards each end of the boat , allowing for efficient distribution of power.

Attached to these masts are various types of sails, including mainsails, jibs or genoas (fore-sails), and spinnakers (used for downwind sailing). The main sail is the largest sail on a catamaran and is hoisted up the mast using halyards – ropes specifically designed for this purpose. Jibs or genoas assist in maneuverability by generating additional power when sailing upwind.

For those seeking exhilarating downwind adventures, spinnakers add an extra element of thrill to your journey! These expansive triangular or bulbous-shaped sails catch wind from behind and propel your catamaran with remarkable swiftness. Learning how to handle these different types of sails will be crucial to seamlessly controlling the boat and maximizing performance on the water.

Next in line are the helm and steering system, responsible for guiding your catamaran ‘s path as it gracefully glides through the waves. The helm, often referred to as the steering wheel , is used to control the rudders located at each hull’s stern. One unique characteristic of catamarans is their tilting tendency caused by wind pressure acting upon the exposed surface area of their broad decks. Therefore, mastering steering techniques, including adjusting sail configurations and keel positions, will help you navigate with finesse and maintain balance.

One particularly innovative feature found in some catamarans is a daggerboard or a centerboard system. Located between the two hulls beneath the waterline, these retractable fins can be individually raised or lowered to vary their depth while sailing. By adjusting these boards according to wind conditions and point of sail , you can minimize resistance, optimize speed, and even prevent lateral drift.

We cannot overlook catamarans’ anchoring systems when discussing their components . Anchors are vital for keeping your vessel secure when moored or stopping for a leisurely swim in crystal-clear waters. Most modern catamarans employ bow rollers integrated at the front end that facilitate effortless anchor deployment and retrieval. With an array of anchor types available — from plows to flukes — it’s essential to understand each one’s characteristics in various seabed environments.

Lastly, let’s not forget about safety equipment onboard! While mastering catamaran parts allows for glorious adventures on calm seas, unforeseen challenges may arise during your sailing odysseys. It’s important always to have safety essentials like life jackets, fire extinguishers, first-aid kits, emergency flares, and navigational tools like GPS systems.

So there you have it – a comprehensive overview of key components necessary for mastering the art of sailing a catamaran! Understanding how each piece of the puzzle fits together and harmonizes uniquely will set you on a path to becoming a skilled catamaran sailor . Whether you’re gliding across tranquil bays or tackling exhilarating rough seas, this guide will equip you with the knowledge and confidence to embark on unforgettable nautical journeys!

There you are, out on the water when a strange craft approaches.  Is it a sailboat? It sure looks like one until it turns to face you.  That’s when you notice this boat doesn’t have just one hull. It has two hulls and it’s called a catamaran.

Catamarans are unique, and highly stable watercraft.  We’ll explore all the ins and outs of sailing the waters in one of these weird, and awesome multi-hulled craft.  Join me as we explore the wild world of sailing catamarans.

A History Of The Catamaran

It is believed that the first people to use a catamaran design were those living in Australasia.

A map showing the region where the catamaran originated.

The succession of boat design in this region was actually very interesting.  The beginning of boats in the area was simple, albeit conventional rafts. These were fashioned from logs strewn together with plant fiber lashings such as those formed using bamboo fiber.  

Catamaran Evolution

An info graphic showing the progression of the evolution of the catamaran.

The conventional raft gave way to a minimal raft.  This design was basically a conventional raft with two cross beams added in the form of logs.  These would be eventually hollowed out to improve buoyancy.

The next step in the evolution of boats in the Australasian region was the double canoe.  This proved to be the first real catamarans.  

After some time, the form evolved further into the asymmetrical double canoe design.  In this design, one canoe was large and the other attached canoe was smaller.

The asymmetrical design quickly evolved into the single-outrigger boat like the one shown in the photo below.

A monohull canoe with an attached exterior outrigger is shown in this file photo.

The final stage of the evolution of the catamaran in the region was to gain a second outrigger.  This in effect created the trimaran with the single central hull and dual outriggers.

Eye Witness Accounts Of Catamarans

In 1697, William Dampier wrote of witnessing a type of seafaring vessel off the coast of Coromandel.  He noted how the locals called the type of boat a catamaran. He also noted that it had multiple hulls (logs) and that they were small vessels that the person operating would have to hang partway into the water, straddling the hull (log).

The name catamaran came from the Tamil.  And yet, it was easily applied by the European visitors to the two hulled sailing vessels that sped across the water in the region.

Although Dampier may have described the catamaran in the 1690s, the type of boat was actually used as early as the 5th century by the Tamil Chola dynasty.  They used boats to move their troops from one island to another. Using this design of boat allowed them to travel heavy, travel quickly and was partially responsible for the conquering of neighboring Burma, Malaysia, and Indonesia.

Building A Boat – Basics Of Catamaran Construction

A boat is usually thought of as being a single-hulled vessel that travels along the surface of the water.  It can have multiple types, shapes, and designs of the hull. However, it is often only thought of as having a single hull.  But, what if it had two hulls? Would that be like taking two separate boats, and making a raft over both of them? In essence, that is exactly what a catamaran is:  two boats made into one.

Advantages Of Multiple Hulls

  • More stability than a monohull
  • Wide supporting base allows for larger sails than monohull craft of the same length
  • Hull does not require the deep-running keel of a standard monohull sailboat
  • Less hull drag in the water than a monohull
  • Less power required to drive a catamaran forward than a monohull boat

Disadvantages Of Multiple Hulls 

  • Due to multiple hulls, construction is more expensive than a monohull design
  • Catamaran speed relies on lightweight materials to make a lightweight craft.  This also drives up the cost of construction.
  • Extra engineering requirements for multi-hull craft also increase the cost of construction.

Conclusion?  Well, it looks to me like everything about catamarans points towards superiority over monohulls in nearly every way.  But, you get what you pay for. I think the same thing likely applies to cars too. For instance, I have a performance car that cost me about 10k more than the equivalent non-sports car within the same class. 

Yet to drive the vehicle, it performs so much better than the normal version of the car, it really speaks volumes to the difference between a common vehicle, and a performance one.

Speaking of performance vehicles, let’s take a look now at the different kinds and uses of a catamaran.

Catamaran Types

Commercial catamarans – ferries.

Catamarans are often used as a ferry to transport people and vehicles across bodies of water as shown in this photo.

One of the most common uses for a catamaran is the commercial use of the vehicle design when it comes to ferries.  This is likely due to the wide, flat deck possibilities of a catamaran versus a monohulled boat. Not only that, but the catamaran is also a much more stable bodied vessel.  This again makes it a superior design for transporting larger land vessels like trucks and so forth. They can easily drive on the ferry without fear of the ferry tipping over.

Some ferries are designed for taking vehicles, like the one you might find in the city of Toronto.  Where it transports cars from the mainland to Toronto Island. Others are designed specifically with the sole purpose of transporting people. I took a look at one such ferry that operates in Germany.  Take a look at the following case study.

Commercial Use Case Study – The Ferry

The FRS Helgoline is a ferry catamaran operating out of Flensburg, Germany, close to the Danish border.

According to the ferry company’s website, the ferry runs using four main engines which are run to a capacity of 12,182 hp combined.  This blasts this ferry at a speed of 35 knots or 65 km/hour. This is equivalent to 40 miles per hour. That’s pretty good considering the size and weight of the ship body this catamaran can carry.

Speaking of capacity, the ship can carry 680 passengers. At 56.4 meters long (185 feet) by 14 meters wide (45.9 feet), that’s a decent passenger capacity. 

Catamaran Passenger Capacity Versus Monohull Boat Passenger Capacity 

The general rule for calculating passenger capacity for a boat is as follows.

Length x Width / 15 = Passenger Capacity

Therefore, the FRS Helgoline should have a calculated capacity calculated as follows.

185 x 45.9 / 15 = 566  

But it actually has a capacity of 680 which is a 20% increase in capacity over a standard monohull.

For comparison, let’s look at a superyacht.  A 48.5m (159 feet) long by 10.7m (35 feet) beam (width of the boat) Palmer Johnson Supersport 48 (valued at about $28.5 million dollars) should have a capacity calculated as follows.

159 x 35 / 15 = 371

In short, 26 feet of difference in length equates to 309 fewer passengers.  It is almost half of the capacity of the catamaran at 26 feet longer length.

Commercial Catamarans – Service Vehicles

In port in Australia, a service catamaran sits docked in this photo.

Although Catamarans are typically used as ferries due to their stability and ability to carry wide loads on their flat decks, there are many different service catamarans out there as well.  From a support vessel to a crew transfer or search and rescue, catamarans are a solid and stable platform to build a ship on.

This is the Ardea which is a 20 meter (65.6 feet) catamaran to be used for crew transport and as a support ship.  This ship was built by the Echo Marine Group and delivered to Western Australia in early 2019. This particular vessel is in the service of the Cape Preston Sino Iron Project.  

Catamarans are used all around the world, for a variety of tasks, not just ferries or support craft.

Commercial Catamarans – Cruise Lines

A large red and white catamaran cruise ship sits idle in the waters in front of a bustling metropolis in this photo.

Now these are the catamarans we all want to be aboard, aren’t they?  Due to the wide stance, these ships can feature massive halls and wide-open interior areas.  These ships are stable, and some would say even more stable and safer than monohull design ships.  

There are many cruise ship catamarans in use today around the world.  Some of the more ‘famous’ catamaran cruises are those which investigate the Galapagos Islands.  There are several high-end, small fleet, cruise lines operating to the Galapagos which utilize catamaran design vessels as their primary ship type. 

These ships can be extremely comfortable and stable and often offer some reprieve to those who may otherwise feel seasick. It won’t stop the feeling, but the more stable the hull, the less the boat rocks around.

Military Catamarans

The USNS Spearhead races forward along the water in this file photo.

Catamarans make excellent military transport vessels.  They are stable and the potential to have a large, flat and wide deck for transporting land craft, troops or acting as a landing pad for vertical take-off aerial craft.  The stability of the two hulls makes the vessel an excellent candidate for military use, and thus it is used for said purpose.

A photo of the rear of the USNS Spearhead - a military catamaran.

As you can clearly see in the image of the USNS Spearhead, the rear of the vessel has a moveable ramp that can be used for loading and unloading land vehicles.  The interior bay of the craft is visible in the image as well, a large area for storage of vehicles, supplies and more. The crane arm on the back of the ship also shows how it is a versatile craft, set up to act as an excellent support craft with a helicopter landing pad and ample storage and freight capacity.

Recreational Catamarans

Siting on a beach, a small catamaran sail is set against the wind swept clouds and blue sky.

Catamaran Personal WatercraftThe wind is in your hair, the warm spray from the hull cutting over the edge of each wave as you skip over the water.  That is life, let me tell you. Personal watercraft have come a long way over the years and the small one, two, three and four-person catamarans have come a long way as well. 

This image shows a homemade catamaran.

Depending on the options, you can get a small one or two-person catamaran for as little as $1500 new.  That might be an inflatable though. There are some very nice, rigid hull designed catamarans for 1-4 people that range from $3500 to $15000.  And these are basically open, personal watercraft like that shown in the image below.

Using a small catamaran can be quite challenging to learn at first.  Sailing is not for the faint of heart. It requires skill, technique, knowledge of the wind and sea, and a bit of hard work.  But it can be fun, rewarding and a great way to catch some sun and fresh air out on the water. It’s a relatively GREEN sport as well.   Given the use of sails over gas-powered motors that is.

‘Sailing Cats’ – Sailing Catamarans – Yacht & Luxury Class

This photo shows a luxury sailing catamaran yacht.

Here’s where we get into the dreamy boats of the rich and famous.  I priced out a small 43’ luxury Leopard 40 sailing catamaran. Even before I added any extras at all, the base price was $399,000 USD.  I imagine if I added a few of the multiple extras available, and some tax, freight and that sort of thing, I’m easily in half a million dollars.  And that’s the smallest base model.

Top-rated boat covers on Amazon

There are all kinds of luxury catamaran shipbuilders across the world.  From Asia to Europe and The Americas, it seems any major boating country has at least one company building luxury catamarans.  It’s weird that you don’t see more of them on the water though, don’t you think?

Being sailing vessels, these luxury cats require some training in sailing before you get behind the wheel.  And considering the price point, I would definitely want to be at least a semi-decent sailor with some good few years experience under my belt before I would comfortable at the helm of a half-million-dollar sailing cat.  It’s all relative I suppose. I imagine a billionaire might bat an eye at the prospect of wrecking a half-million-dollar boat. But to me, and most of you reading this, that’s likely a lot of money.

‘Power Cats’ – Powered Catamarans

A powered catamaran is shown in this file photo.

The powered catamaran is one of my favorite boats.  They have sort of a muscle car appearance with the wide and often tall front end of the boats.  I find it to be reminiscent of a large air intake on the front hood of a rally race car like the Subaru WRX, for instance.  These boats are fast, they are stable and handle very well. Catamarans are often considered the boat of choice for long sea voyages due to their stability.  

A powered catamaran will definitely cost more than a powered monohull boat of the same length.  Why? Well, the powered catamaran has one crucial downside. That is, it needs two engines. One for each of the two hulls.  Otherwise, it’s off balance for propulsion. These two engines or motors have to be in sync with each other or again, the propulsion will be off-balance.  Because they have two motors, they have double the maintenance when it comes to maintaining the propulsion system.

More components also means a greater chance of things breaking down.  In essence, it doubles the chances of the ship having a motor break down. The saving grace is that should one motor break, they have a backup, even if it does mean very unbalanced propulsion.  In contrast, a monohull vessel of the same length may only have half the chance of motor failure due to only having one motor, but if that one motor breaks, then what? Call for help, that’s what.  A cat would have a struggling chance to get itself back to port. A monohull would be dead in the water unless it was carrying spare parts or another motor onboard somewhere.

Catamaran Frequently Asked Questions

What is a catamaran cruise.

catamaran hull name

A catamaran cruise is simply a cruise on a dual hull design boat.  Often used for river cruises, the catamaran which is used as cruise ships are often considerably smaller than their giant monohulled counterparts.

What is the purpose of a catamaran?

A catamaran is a design for a boat that utilizes two hulls.  Due to the flat, platform-like-potential for the deck of the boat, the catamaran is often purposed with transporting materials, vehicles, and people.  For instance, catamarans are quite often used as ferries.

Is catamaran safe?

Catamaran are very safe water craft.   The design of riding on two hulls separated by a gap in between, in essence is like giving a car a double-wide wheel base.  The wider the stance, the more stable the craft, from side to side anyway. And if the length of the boat is proportional to the width, then it becomes an extremely stable craft.  That is why catamarans are often considered the best to be used for long voyages. Yes, catamaran are safe.

What is the difference between a catamaran and a sailboat?

A traditional sailboat is a deep, monohull vessel that has at least one mast extending high into the air above the deck to hold sails.  A catamaran refers to the design of a dual-hull boat and really has nothing to do with sails. Although, catamaran do make excellent sailing boats as well, they are quite capable of acting as power boats and do not require sails if they have the correct amount of powered motors to propel them.  Sailboats, although also able to be powered if a motor is provided, are traditionally monohull and wind-powered exclusively.

Do catamarans have small interiors?

The size of an interior cabin on a boat is typically proportional to the size of the boat itself.  If a catamaran has above-deck cabins, they will likely be able to be of a larger design than those you would find on deck of a monohull boat.  This is because a catamaran has a much wider footprint than a monohull boat of the same length. This extra width would allow for larger on deck cabins.  

How much does a catamaran cost?

A personal watercraft (1-2 person) inflatable catamaran will run you anywhere from $1500-$12000 USD, depending on the quality and features.  The rigid hull catamarans of the same size start at about $4500 USD.

Top-rated boat lights on Amazon

A small cabin cruiser type of catamaran will typically start at about $60000 for a small base model and the price just goes up and up depending on size and features.

For Instance, a 40’, 3 cabin with 1 washroom cat will cost you about $500,000 USD for the base model.  They are considerably more expensive that a monohull of the same length. However, the trade-off is greater stability and a smoother, more comfortable ride.

Is a catamaran more work to maintain?

Technically yes.  Due to having two hulls and if powered, two motors and likely also water jets, this means you have double the oil changes of a boat that would have a single motor.  Once you get past the basic engine and hull maintenance, a catamaran is not that much more work than a monohull ship of the same length.  

The trouble with catamarans in terms of maintenance, is that once they reach a certain length, the width becomes more than a standard lane on the road.  That being said, if you ever need to transport the boat via land, it can be quite the challenge. Especially if you need to pay to have a police escort for an extra-wide trailer.  And special licensing might be involved as well.

What is the difference between a catamaran and a trimaran?

A trimaran is shown in this photo.

A catamaran is a dual hull boat.  In other words, it has two hulls. A trimaran has three hulls.  

Is a catamaran considered a yacht?

According to Oxford dictionary, a yacht is a medium-sized sailboat equipped for cruising or racing.  A catamaran, on the other hand, is a boat with two hulls. Therefore, a catamaran can most certainly also be a yacht.  And likewise, if a yacht has two hulls, then it is a catamaran as well.

Can you get seasick on a catamaran?

Seasickness occurs when a person feels nauseous from the swaying motion of a rocking ship.  These feelings may be lessened on a catamaran, due to their extra stability. However, a catamaran may be slightly more stable than a monohull of the same length, but it is still a boat.  And it will still make someone who experiences seasickness continue to feel the ill effects.

Are catamarans more stable in rough seas?

Catamarans are known to be more stable than monohull ships of the same length.  This is why catamarans are often the ship type of choice for long sea voyages due to their stability.

Why do catamarans capsize?

Catamarans are not known for capsizing.  The larger vessels that is anyway. But, it does happen from time to time.  Catamarans are known for their stability, so typically if a capsize event should occur, it is typical for them to be extreme circumstances.  

Top-rated canoe accessories on Amazon

Personal watercraft catamarans are a different story though.  These are in fact known for tipping over. Not because they are less stable than their monohull counterparts of the same length.  But instead, because they are able to go considerably faster than monohull personal watercraft of the same length (not including powered craft though).  This is due to the sailing cats being able to have a larger sail than a small monohull sailboat of the same length.

Due to the extra sail, they are able to travel faster than monohull sailboats of the same length.  This allows them to whip around on the water and at higher speeds, whipping your cat about quick can easily send it over sideways. Extra speed means fast turns carry momentum in the direction of travel and that extra speed equates to tipping over if turned too fast.  To sum up, they capsize due to user error or extreme events.

Which is safer, a catamaran or a monohull?

Due to the extra stability of having a wider footprint than a monohull, a catamaran of the same length is the safer vessel.

Are catamarans safer than sailboats?

The same rule applies to stability versus the length of the hull.  A cat will always be the more stable length for length. However, due to their ability to go much faster than a monohull sailboat, this kind of cancels out some of the added safety due to stability.  With that in mind, they may just be about the same but there is one generalization we can make when comparing the safety of catamarans vs sailboats: At the same speed, and of equal length, sailing or power catamaran will be safer than a monohull sailboat.

How fast can catamarans go?

The speed a catamaran can go is entirely dependent upon the hull design, weight of the vessel, the strength of propulsion (be it wind or powered) and so on.  The general rule is that in terms of sailing cats vs monohull sailboats, a cat of equal length can typically go faster than a sailboat.  

In terms of powered cats vs powerboats, a powered catamaran will typically require less energy to move forward than a monohull of the same sort of hull design (but monohull of course) and thus a cat should, in theory, be able to go faster than a monohull when both are using propulsion that is equal in power.

How Many Hulls Does A Catamaran Have?

How Many Hulls Does A Catamaran Have? | Life of Sailing

Last Updated by

Daniel Wade

August 30, 2022

‍ Catamarans are some of the most well-regarded sailboats on the water, and they offer numerous handling advantages over monohulls. But how many hulls can a catamaran have?

All catamarans have two hulls arranged side-by-side. Catamaran hulls are separated by a gap that is many times wider than the hulls themselves. Outriggers, which have a large primary hull and a small outer hull, or sometimes considered catamarans as well.

In this article, we'll go over how many hulls a catamaran has, how they're configured, and how they compare to other common single and multihull boats. Additionally, we'll cover why catamarans are designed the way they are and go over the advantages and disadvantages of the catamaran design. We will also cover common lookalike vessels and how to distinguish them from catamarans.

We sourced this information from widely used sailboat design and identification guides, along with our own experience in the sailing community.

Table of contents

‍ Catamaran Hull Configuration

The hull configuration of a catamaran is simple and easy to identify. Catamarans Have a wide stance and consist of two identically shaped narrow hulls connected at the tops. The hulls are an exact mirror of each other, and there's a large space or platform in between them that provides room for a cockpit, living spaces, and even a trampoline.

Catamarans vary widely in shape, size, and configuration. However, it's easy to spot a catamaran by simply counting the hulls. Any sailboat with two identical hulls side-by-side is a catamaran. A sailboat with a large primary hull in a small outer hull is likely an outrigger, which is a rare type of catamaran.

Why Do Catamarans Have Multiple Hulls?

Catamarans have multiple hulls for speed and stability. The stability advantages of incorporating two narrow hulls and spacing them widely apart are easy to identify. This wide stance makes it very difficult to tip a catamaran in either direction, which increases sailing comfort and significantly reduces rolling in heavy seas.

Speed is another reason why catamarans have two hulls. Catamarans can travel at much faster speeds than monohulls because they're not bound by the rules of hull speed. When a monohull travels through the water and creates a wake, the bow and stern waves will synchronize and interfere with the speed of the boat. When these waves synchronize, the monohull has great difficulty traveling any faster.

Catamaran hulls also generate wakes, but the two side-by-side hulls effectively cancel out the synchronous interference that slows monohulls down. Additionally, the narrow design of the hulls allows them to pierce through waves instead of riding over them, which reduces travel distances and increases efficiency.

Another reason why catamarans have two hulls is that the design reduces draft. The draft is a measurement of how deep in the water the hull extends, and catamarans have some of the shallowest draft-to-length ratios in the sailboat design world. That means that a comparatively large catamaran can travel in much shallower water more safely than a monohull.

Are There Other Multihull Sailboats?

Catamarans are the most common multihull sailboat design, but there are several others available as well. The most common multihull other than the catamaran is the trimaran. As the name suggests, trimarans have three hulls instead of just two. The trimaran usually has two narrow hulls and a larger hull in the center, as the primary purpose of the outer hulls is to provide stability.

Catamarans and trimarans are known for speed. And while catamarans can double or even triple the speed of an equivalently-sized monohull, trimarans can go even faster. This is because trimarans are not bound by the rules of hull speed either, and they create less drag-inducing hydrodynamic interference than catamarans.

Catamaran vs Monohull

Catamarans have a number of distinct advantages over monohull sailboats. The most obvious benefit to experienced sailors is the increased stability of the multihull design. Picture it like a table. A table with wide legs is going to be more stable than a table with narrow legs. Leaning on it won't knock it over as easily—and the same is true out on the water.

Catamarans can also be more spacious than monohulls, without additional size in terms of length. The catamaran is a very old design, as even ancient boatbuilders knew of its advantages. However, there are some downsides to catamarans and other multihull designs, which is why monohulls are still the most common kind of sailboat on the water.

Monohulls are easy to construct. Unlike a catamaran, which must have a carefully designed load-bearing structure connecting the hulls, monohull sailboats derive all of their strength from the hull itself. In other words, there aren't as many weak points, and it's easier to build. Additionally, it's also a lot cheaper to build a monohull, in the design doesn't have to be quite as precise.

Another advantage of a monohull sailboat is that it's easy to configure the interior. If you need more space for accommodations, engineers can simply widen the hull during the design phase. Catamarans have very narrow hulls comparatively and can be hard to effectively utilize space without unnecessary redundancy or cramped quarters. Monohulls are also much more efficient for transporting cargo, as the hulls are wide enough to fit a vast amount of material.

Catamaran Hull Size

Catamarans come in all shapes and sizes. And unlike monohulls, overall length is not the primary deciding factor when it comes to performance. When you picture a catamaran, you're probably thinking about one of the large glossy cruising sailboats that often dot coastal anchorages across the world. These vessels usually range in size from 35 to 55 feet in length.

There are different types of catamarans. The most common kind, known as cruising catamarans, or usually around 45 feet in length. The smallest cruising catamaran is around 30 feet long, as catamarans don't have enough hull for comfortable accommodations at a size smaller than this. Cruising catamarans can reach astounding sizes, often exceeding 50 or 60 feet in length.

The beam, or width, of catamarans, is usually much more significant than monohulls of the same length. This is despite the fact that catamaran hulls are significantly more narrow than other types of vessels. For example, a 40-foot monohull likely has a beam between 10 and 14 feet, whereas a 40-foot catamaran can have a beam of 20 feet or more.

These factors have a positive effect on seaworthiness, as catamarans don't heel over under heavy sail and are extremely difficult to capsize. Additionally, they will float just as well upside down as they do right side up.

However, this additional beam can make docking a catamaran challenging. Marinas that can normally accommodate two large monohulls in a slip can only fit one catamaran in the same space, leading to increased mooring fees.

What Are Catamaran Hulls Made Of?

Catamaran hulls are made from all sorts of materials. The most common catamaran designs use fiberglass, which is a moldable mixture of hard glass fiber and waterproof resin. Fiberglass has been the primary recreational boat building material across the world for more than 60 years, and the technology is better than ever. Fiberglass catamaran hulls can theoretically last forever, they can be molded into any shape at the factory, and they're easy to repair.

The finest custom cruising catamarans are made from aluminum. Aluminum is an extremely costly but highly desirable catamaran building material, as it reduces weight and allows these vessels to reach extremely high speeds. Due to the cost and technical experience required to build an aluminum catamaran, the vast majority of boats are fiberglass.

Wood is occasionally used to build catamaran hulls. Today, most wooden catamarans are made from marine plywood and sheathed in a layer of fiberglass for strength and waterproofing. Traditional wooden construction is only found on outriggers, as it is costly and very time-consuming.

What Are Outriggers?

Outriggers are a type of catamaran that traces its roots all the way back to 3000 BC. An outrigger is a simple open boat with a stabilizing hull mounted off to one side. Some outriggers, especially canoes, have two stabilizing hulls.

Outriggers, while technically catamarans, are not widely used in the 21st-century due to their lack of space and one-sided stability. However, these vessels are an important part of catamaran history and a great demonstration of how multihull designs can add great stability to a boat.

Boats come in a wide variety of shapes and sizes—and so do their hulls. Despite the variety, all hulls are designed to do one of only two things: either displace water, or ride on top of it, which is called planing. Sailing boats, slow-moving boats, and large boats like cruise ships have displacement hulls. The combination of their weight and power means they move lower in the water, pushing or displacing water, rather than riding on top of it. Smaller, faster boats, like powerboats or personal watercraft, typically have planing hulls. Planing hulls are designed to rise up and ride on top of the water at higher speeds. Now let's look at some specific hull types.

There are four common types of boat hulls.

Flat-Bottom Hulls

Boats with "flat-bottomed" hulls are very stable, great for fishing and other uses on calm, small bodies of water.

Round-Bottom Hulls

"Round-bottomed" hulls are typically displacement hulls, and are designed to move smoothly through the water with little effort. An example of a round-bottomed hull is that found on a canoe. One drawback to the round-bottomed design is that it's less stable in the water and can capsize more easily. So, extra care needs to be taken when entering, exiting and loading these types of boats.

V-Shaped Hulls

"V-shaped" hulls are planing hulls, and are the most common type of hull for powerboats. Deep v-shaped boats are designed to plane on top of the water at higher speeds and provide a smoother ride through choppy water. These boats are usually equipped with a larger engine than flat or round-bottomed boats.

Multi-Hulled

Finally, let's look at "multi-hulled" boats. These boats can have either planing or displacement hulls depending on the shape of hull and size of engine. Multi-hulled boats are some of the most stable on the water. They also require more room to steer and turn. Examples of common multi-hulled boats are catamarans and pontoon boats .

What Is a Catamaran?

If you’re thinking of chartering a catamaran on your next trip, read through our guide and get up to speed on two hulled yachts! We offer Catamarans for charter in over 60 countries and the entire selection can be seen on our Catamaran charter page.

A Catamaran is a sail or engine-powered boat with a double hull, a distinct feature that makes it immediately recognizable once you're aware of the design. People often question whether a catamaran is a yacht, and due to the sleek style, versatility, speed capabilities, and comfort, a catamaran definitely earns the yacht stamp of approval. Due to these same characteristics, catamarans are becoming an increasingly popular choice among avid leisure and sport sailors.

The elegant and unique catamaran style isn't a new development - it's actually a centuries-old design that's been modified and built upon to become what it is today.

The first Catamaran was created in India, borrowing its modern name from the original Tamil word kattumaram, meaning "logs bound together". The first design was simply a raft made of tree trunks, built in the fishing communities of Tamil Nadu in southern India and used to invade several Southeast Asian countries as early as the 5th century. The kattumaram quickly became the favoured vessel style throughout Polynesia and Micronesia.

Evolved by American Nathanael Herreshoff in the 1870s and further developed in the 1950s, the catamaran concept really took off in the 20th century. It was soon functioning as a full-fledged yacht, able to compete in the racing arena with mono-hulled boats without compromising luxury. Nowadays, catamarans attract both sport and leisure boaters with its versatility, speed, and comfort.

What are the Characteristics of a Catamaran Hull?

The most obvious characteristic of a catamaran is the twin hull, but there are more benefits to the cleverly crafted underside. When compared to a monohull yacht of the same size, the catamaran hull has several big advantages. Catamaran hulls are noted for having less volume, lighter displacement, and shallower draft (ie less of the boat is below water) when compared to monohull vessels. The shallow draft is especially appealing, allowing for use in shallow water and giving the captain the option to pull the boat right up to shore without worry.

Additionally, because of the hull design, catamarans boast a smaller hydrodynamic resistance, ultimately making them more economic since they don't need as much fuel to propel them forward. And for those sailors still strengthening their sea legs, the double hull increases the catamaran's overall balance and stability by reducing the amount of wave-induced motion. So long seasickness!

Catamarans have a lot of space. The living area in between the two hulls offers a dining and lounging area as well as a spacious kitchen. You also find outside lounging areas at the back and in the front of the yacht. The various places to relax mean a lot of privacy on board. The two hulls further increase the privacy aspect because the cabins are separated by the central living area and each hull has their separate entrance in most cases. This makes the Catamaran the ideal yacht to charter for two couples, two families, a group of friends or a large family. The cabins in the hulls are spacious and comfortable and their sizes vary with the exact Catamaran model.

So in summary, catamarans:

  • have two hulls, usually connected by a bridgedeck
  • can be sailed in shallow water
  • use less fuel, because they have low hydrodynamic resistance
  • tend to be very stable
  • have a lot of space for dining and lounging and preparing food
  • offer greater privacy than monohull yachts

To give you an idea of the space and amenities on board a Catamaran, do have a look at the many pictures of our Fountain Pajot Alegria 67 for charter in the British Virgin Islands .

How to Sail a Catamaran

You're sold on the idea of a catamaran, but now comes the question, how hard is it to sail a catamaran? Learning how to sail a catamaran is relatively straight forward if you're already trained in the basics of sailing. Although it does differ from monohull vessels, the idea is the same. Be prepared to tweak your sail trimming skills and get used to the difference in motion (or lack thereof) with the catamaran.

The catamaran is gaining popularity because the better-balanced hull and twin engines make it arguably easier to operate than a monohull yacht. Fluid maneuverability means that even one person can sail a catamaran as long as they've built up enough sail experience. Still, it's never a bad idea to get some formal training; the ASA and RYA both offer catamaran sailing courses to help enhance your skills.

How Fast Can a Catamaran Sail?

Catamaran's can cruise! Their speed is just another reason why the boat has become so sought-after in recent years. A sailing catamaran can typically perform 25% - 30% faster than a monohull of the same size.

So just how fast can they go? Cats average about 10 knots with top speeds reaching around 15 knots. Just keep your weight in mind - catamarans respond sensitively to heavy loads and will perform slower if overweight.

catamaran hull name

Why Charter a Catamaran?

When compared to a monohull boat of the same size, a catamaran has a tendency to be a bit more expensive to charter. However, your trip itinerary might require certain criteria that make spending a bit more worth it. For example, the flat plane and stability of a catamaran are ideally suited for a family to enjoy their holidays in a lot of comfort. It is also ideal for a scuba diving holiday , allowing divers to gear up and enter/exit the water with ease. Additionally, big parties usually find catamarans better suited for their needs in terms of deck space and overall comfort.

A Catamaran is the ideal yacht for a relaxing vacation as it boasts a lot of space, stability and living spaces - it truly is your floating hotel. But note that a catamaran holiday does not need to break the bank and is very affordable in comparison to a vacation in a hotel or a villa depending on the type and size of a catamaran you decide to go for. 

***************************

Catamarans are a fun alternative to the traditional sailing yacht and the value for money is unrivalled for a yacht holiay. They provide comfort, flexibility and a lot of space to spend your time on the sea. You can also check out this Comprehensive guide to chartering a yacht for more information.

Main Types of Catamarans Used in the Shipping World

A catamaran is a boat with two hulls instead of a monohull which the traditionally designed sailing boats have. They were designed to be fishing boats though their use has increased today. Generally, they have more interior space, saloons and cabins than a conventional sailing vessel.

The following points will enable us to understand the boat and its types clearly.

Origin of Catamarans/Cats

The fishing community ‘Paravas’ in Tamil Nadu first created the catamaran in the 17 th century. The main feature of these boats was that they had two hulls which offered a lot of stability and balance compared to the other fishing boats of that era. This concept of two-hulled boats was adopted by the British and then made famous across the world.

Present-Era Cats

In the present times, cats have evolved from being mere sailboats or fishing boats. There are two basic design types of catamarans: Pontoon and SWATH (Small Waterplane Area Twin Hull).

The former is relatively small, compact and uses floats (known as pontoons in marine slang) as a major technology to propel the water along with the dual hulls. In contrast, the latter is quite large and is designed primarily to maintain balance in sea areas with unpredictable currents and tides.

It has to be noted that in today’s times, all variations of catamarans are made of fiberglass or carbon fiber. They are motorised and engine-powered, making them even more reliable than they used to be before.

Physical Characteristics of Cats

Generally, charter catamarans have twin engines, one in each hull to manoeuvre. It also has a mast that supports the mainsail and another for the headsail. Power cats are an example of innovation, offering the best experience.

Power cats or multi-hull powerboats have large engines and no masts or sails. Their powerful motors give them high speeds, and their reinforced hull types handle their weight. Their demand is growing daily, and they are available in many stylish designs. Another feature of cats is that they can go into shallower waters, as they don’t have deep keels.

Catamaran sailboats have a minimum sail area of 470 square feet and a maximum of 2260 square feet. Some famous builders are Robertson and Caine, Lagoon, Seawind, Fountaine Pajot, Gemini and Leopard. They make catamarans with secondary inboard, outboard, electric and other propulsion systems in diesel, gas, and other fuel systems. Custom-made catamaran sailing vessels are a speciality of the Privilege Shipyard. Usually, the vessel’s average capacity depends on its size. Some can carry about 16 to 60 people.

These new vessels are sought for their rich legacy, greater draft and wide beam, which make them excellent for overnight cruising and day sailing.

Catamaran

Some of the main types of catamarans can be elaborated as follows:

Cruise Catamarans

These catamarans are also known as luxury catamarans or ferry catamarans. This is because they offer the best possible luxury to the passengers who take a trip in such ferries. And the addition of engines has made such ferries even more attractive to the crowd.

Also, the space between the two hulls is filled by a cockpit, a main cabin and netting for relaxing in the sun. Their size and stability is the reason for their popularity. With two hulls, there is enormous space on a catamaran above and below the decks, which provides comfort on sailing vacation. Hence, they are preferred by vacationers for their unique characteristics.

Cruise Catamarans

They also offer great speed, which ensures that the passengers get the cruise trip of their choice without any lapse in time. It has to be noted that luxury catamarans operate not internationally between nations but internally within a country.

Some popular cruise catamarans worldwide are the Stena Voyager (operating in the Irish Sea) and Victoria Clipper IV (operating between Seattle and Victoria in the USA).

Sailing Catamarans

  Catamaran sailing is another type and utility of a catamaran. Sailing catamarans are used for recreational purposes by people who want to experience the life of a sailor.

Catamaran sailing does not involve any place for residing in the boat. In other words, catamaran sailing can also be referred to as catamarans used as yachts .

The average speed achieved in a day in a sailing catamaran is up to 300 nautical miles. Such catamaran sailing was first introduced in Europe though it has started gaining popularity worldwide.

Sailing Catamarans

It has to be noted that catamarans are quite novel in their creation and development. Unlike other boats, they have not become inoperative or extinct.

Their name still commands unique respect, making a catamaran adapt more successfully to the changing era and times .

Frequently Asked Questions About Catamarans

1. what are catamarans used for.

Catamarans are a preferred option for day sailing, cruising, fishing etc. Many boat charter companies offer their customers yachts, motor yachts and catamarans. Though their design dates back 100 years, the updated and technologically updated catamarans have a massive demand in the sailing market.

2. What are the disadvantages of catamarans?

Catamarans are 150 to 200 per cent more expensive than yachts of the same length. Also, special marinas are built for these vessels due to their width. Also, they are costlier to maintain and repair than other similar vessels.

3. What is the speciality of catamarans?

Catamarans offer more stability as they have two hulls, which decrease the chances of people falling overboard. They are larger and more comfortable than normal sailing boats, not to forget their eye-catching designs.

4. Do they have washrooms?

Today, catamarans have all amenities, including saloons, seating areas, well-fitted washrooms and plenty of interior space. Also, during bad weather, they can be steered from inside.

5. What is the lifespan of a catamaran?

On average, a catamaran can last for 15 to 25 years and even 30 years if it is well-kept and maintained. Its lifespan also depends on the usage, type, quality of construction material etc.

Boat Hull Types, Shapes & Designs

boat hull types

10 Common Types of Boat Hulls

Displacement hulls, planing hulls.

  • Flat Bottom
  • Tri-Hull (Tunnel Hull)

Semi-Displacement Hulls

Multi-hulls.

Explore Different Boat Types

Large ships, some trawlers and traditional recreational sailboats have displacement hulls. They are slower moving but quite steady under way and are capable of carrying large loads with relatively small propulsion units. Displacement hulls are usually round on the bottom with ballast placed low in the center. At rest, round hulls tend to roll with the waves and swells.

displacement hulls

Most powerboats and personal watercraft have planing hulls that ride on the water at higher speeds. They behave like displacement hulls at low speed but pop up onto a plane usually around 15-16 MPH depending on the design and load. Planing hulls come in a variety of shapes, each of which has it benefits and disadvantages.

Flat Bottom: Flat-bottomed boats are very stable and can carry a heavier load. They require only a small engine to get on plane but can ride rough and wet in chop or heavy weather. Small aluminum or fiberglass bay and fishing boats often benefit from flat hulls, which have a shallow draft and provide a good amount of deck space both of which are ideal for fishing on calm bodies of water such as small lakes and ponds or slow rivers.

flat bottom hulls

V-Bottom: Deep V hulls cut through waves and ride smoothly in chop. They take a bit more power to push up onto a plane, tend to roll or bank in sharp turns and due to the angle of the hull, have less interior volume for stowage or accommodations. Fast, distance fishing boats like center consoles tend to have a V bottom so they can run fast on open water to get to the fishing grounds quickly.

Tri-Hull or Tunnel Hull: Popular with fisherman as well as with sport boat enthusiasts, tri-hulls, also called cathedral hulls, have a combination M-shaped bottom. They’re quite buoyant and stable and they get on plane quickly. They offer good volume below and significant deck space above. At speed, they tend to pound when they encounter choppy water so they’re ideal for lakes of calm bays.

Pontoon: Pontoon boats ride on (typically) aluminum tubes. Traditional pontoons have two tubes but newer designs have three and are called tritoons . Pontoon boats are all about deck space and make excellent boats for families and entertaining on the water. The newer tritoons can carry large outboards and so they’ve become planing boats capable of towing for water sports or reaching distant fishing spots.

Learn More: Tritoon vs. Pontoon

boat hull types

Semi-displacement hulls combine rounded sections for increased storage and tankage, and flatter hull sections to partially lift the forward part of the hull out of the water, thereby decreasing drag at high cruising speeds. They generate large bow and stern waves and may need high horsepower engines to get on plane. Larger, cruising motor yachts lean toward the semi-displacement design.

Boats with separate and distinct hulls are called multi-hulls and can be catamarans or trimarans. Multi-Hulls can be either power or sailboats and have displacement or planing hulls depending their shape and the size of their engines.

Catamarans: Catamarans have two hulls with a deck or trampoline in between. Their benefits include excellent stability and depending on size and type, significant living space aboard. Large cats (35 feet and over) have become popular in charter use because they offer more interior and deck space and an easier motion to induce less seasickness. With two engines, catamarans are very maneuverable but they do require more room to turn and berth. Small catamarans usually have just a trampoline in between the hulls and make fun daysailers.

Trimarans: Trimarans are often (but not always) sailboats. They have three hulls: a main hull and two amas (side hulls used for stability). On some smaller trimarans, the arms that hold the amas can fold inward, making the trimaran narrower and in some cases trailerable. Trimarans require smaller engines and they sail faster primarily due to the reduced wetted surface (the area in contact with the water), which cuts down on drag.

When choosing a boat type, consider your primary use for the boat and let that guide you to the optimal hull shape.
