“The design office were told specifically by me that if this boat wasn’t the worst rated boat in history they have failed,” Dr Jim Clark said about his new raceboat. Not exactly the sort of remark you might expect, perhaps, but Clark, founder of software company Netscape, is well known for his singular approach to his many sailing ventures.

For Clark, owner of the 295ft three-masted schooner Athena and the replica J Class Hanuman , the goal for his brand new 100ft super-maxi Comanche is first and foremost to break records.

At her first major outing in the Rolex Sydney Hobart Race 2014, she caused something of a stir, although she was pipped for line honours in the 650-mile offshore classic by the well-sorted and immaculately sailed Wild Oats XI .

Not surprising that Clark should look to his regular skipper Ken Read and the French design team collaboration of Verdier Design/VPLP to create his new master-blaster. Despite a punishing one-year timeline for the build team, project managers Tim Hacket and Brandon Linton worked with boat captain Casey Smith – all three were involved in Read’s previous Volvo campaign – to see the new boat launched on time from the Hodgdon Yard in Maine in late 2014, given an impressive first run in heavy airs and then put on a ship to Sydney.

Under sail, first impressions of Comanche  inevitably draw comparisons with IMOCA 60s and the globe-circling multihulls in which the design team excels. With massive beam at the stern, long reverse sheer, the mast well aft of 50 per cent of the boat length, towering narrow mainsail and a long boom overhanging the stern, everything is built for speed when the wind is abaft the beam.

In anything above eight knots of true wind Comanche starts to move out of displacement mode and at 25° of heel she has the same wetted surface as the 100ft supermaxi  Wild Oats XI – the more remarkable when you consider that you could fit two of Wild Oats ’s sterns into Comanche ’s.

Helming Comanche requires a different mindset, according to Read: “You sail the boat a bit like a multihull in a way, it’s so wide you rock it up on its ‘leeward hull’.”

So beamy is Comanche that she was given the nickname the Aircraft Carrier

The photos below show exactly what this remarkable yacht looks like on deck and below.

STERN Comanche ’s beamy stern swiftly earned her the tag The Aircraft Carrier. Her optimum heel angle is anything over 20°, while at 25° she has the same wetted surface as Wild Oats XI . The fitting of an escape hatch and the liferaft stowage in her stern are a direct result of lessons learned from the capsize of Rambler in the 2011 Rolex Fastnet

MAST As with the IMOCA 60s, the mast is positioned well back in the boat; sited directly above the canting keel, the mast is deck-stepped on a triangulated mast post integrated into the same frame as the keelbox. Static loads on the mast base are in the order of 75 tonnes, increasing to 150 tonnes under sail

DEFLECTORS The 150ft (46m) four- spreader rig features two running backstays and three deflectors, precluding the need for checkstays for mast bend control, and also reducing windage and weight aloft. Mast height was limited to be able to pass under Sydney Harbour Bridge

COCKPIT AND WINCHES Sail handling is by grinder-powered Harken winches with customised drive shafts, grinder pedestals and gearboxes to cater for the substantial torque. The winch pedestals are placed inboard to permit stacking of up to four sails in the cockpit

WHEEL POSITION The steering pedestals can be moved to a position at the forward end of the cockpit (ringed), just behind a detachable hard dodger over the companionways, affording the helmsmen and crew maximum protection if required for long passages

DEFLECTOR RAMS The three deflectors controlling mast bend are trimmed by three hydraulic rams that work interactively. Although cheat sheets have been developed for basic settings, the crew is still exploring setting refinements for these

CANTING KEEL The canting keel is controlled by a 350kg titanium ram built by Cariboni. The keel can be swung 35° either side of centre and moved through the full arc in about 25 seconds. A secondary slave cylinder can be used to swing the keel if the primary ram fails

WATER BALLAST Manifolds, pipes and valves controlling water ballast are located behind the navstation bulkhead. Water ballast comprises 6.5 tonnes per side in three tanks on each flank. All pipework is built in carbon fibre

COMPASS The cheapest fitting on the boat is a card compass that would look more at home on a Laser. Though the helmsmen and trimmers use the digital read-outs, the rules require a card compass to be fitted, so the team went looking for the simplest and lightest

NAVIGATION STATION is located immediately behind the companionway bulkhead, also being the point from which all the boat’s electrics are controlled. The carbon fibre chart table can be tacked and the bench seat is long enough to allow the navigator to sleep or rest here if required

TACKING HEADS There are two concessions to ‘luxury’ aboard Comanche , one being a carbon fibre tray for six coffee cups and the other a carbon heads that can be tacked! No privacy for the latter, of course

Average Sailboat Mast Height

Last Updated by

Daniel Wade

August 30, 2022

‍ Sailboat masts are known to be quite tall, but how tall do they get? The answer varies on rig type, boat size, and design attributes.

Small sailboats, under 20 feet in length, rarely have masts taller than 20 ft or shorter than 8 ft. Sailboats between 20 and 30 feet have masts up to 30 feet tall, and large 40+ foot sailboats often have masts that exceed 50 feet in height.

In this article, we'll cover the average mast height of various sailboats based on length, and we'll also provide a typical height range. Additionally, we'll compare mast height by rig type. Finally, we'll cover the benefits and disadvantages of tall and short masts.

We sourced the information used in this article from sailboat design guides and the sailing community. Additionally, we analyzed several boats from each length category to determine average mast heights.

Table of contents

‍ Why are Mast Heights Different?

If you spend enough time around marinas, you'll undoubtedly notice the numerous masts that tower high above seemingly minuscule boats. Some are tall and thin, some are short and fat—and many are somewhere in between. So why do sailboat mast heights differ so much?

There are a lot of factors that contribute to mast height, not the least of which is boat size. Obviously, boats need a sail plan proportionate to their length, beam, and displacement in order to be efficient. The type of sail plan varies based on what the boat is used for.

Different rigs use different mast heights, even if the boat underneath is exactly the same. Let's assume we have two identical 30-foot boats. One has a tall mast and a triangular Bermuda rig, while another has a shorter mast with a four-sided rig.

The four-sided sail has a much greater area per foot of height than the triangular sail, so the mast doesn't need to be quite as high. Additionally, shorter masts can be thicker and stay within the same weight limits as a taller mast, so they can be thicker and stronger.

Average Mast Height by Sailboat Length

Now, we'll look at the average mast heights of sailboats by their overall length. We're not considering rig type beyond the fact that the majority of modern sailboats are Bermuda-rigged sloops—we'll get into that later. Here are some averages based on popular sailboats.

As you can see, the average mast height is highly dependent on the length of a sailboat. Most vessels have triangular rigs, which require a taller mast. It also seems as though mast height isn't usually far from the overall length of the boat, at least on tall single-masted vessels.

Why do Racing Sailboats Have Tall Masts?

Racing sailboats are known for their crazy mast heights and long, thin sails. There's a very simple reason for this, and it has to do with efficiency and drag. A taller and thinner sail is much more efficient for speed than a shorter and fatter sail. The same goes with the dimensions of the hull, as fast boats tend to be long and slender.

The science behind sail design is ancient and fascinating. In the 21st century, where the boat market values speed and agility, tall masts with thin triangular rigs are becoming increasingly popular. Short-masted vessels, once a key component of working offshore, are more durable but less common.

Average Mast Height of Multi-Masted Sailboats

Having multiple masts has distinct advantages, especially for cruising. Multi-masted sailboats are some of the best offshore cruisers ever built, and they are also remarkably durable. One of the main benefits of having multiple masts is that it adds a level of redundancy and increases your ability to finely control the vessel.

Multi-masted sailboats almost always have shorter and thicker masts when compared to similar single-masted vessels. Sailboats with four-sided mainsails, such as many classical schooners, are a particularly extreme example of this.

Gaff-rigged schooner masts are significantly shorter than triangular rig masts, sometimes more than 10 to 20% shorter. It's often the case that these vessels have a topmast that can be raised or lowered to add a triangular topsail, further increasing the area of the large four-sided sail plan.

What Sailboat Rigs Have Tall Masts?

Bermuda rigged sailboats (also known as Marconi rigged sailboats) are the most common tall-masted boats. Triangular rigs are tall because their sail area decreases as it moves up the sail, so they make up for it by adding height.

Fully-rigged ships also have very tall masts. These are the traditional sailing ships that are quite literally called 'tall ships' in the sailing community. They have multiple sails on each mast when fully deployed, and they usually have three or more masts and multiple headsails.

What Sailboat Rigs Have Short Masts?

The gaff rig is a common and classic sailboat rig that uses traditionally shorter masts. The gaff rig uses a square mainsail, which has more lateral area than a triangular mainsail. These vessels often deploy a topsail with or without a mast extension called a topmast.

The lateen rig is also famously simple and short-masted. It uses a triangular sail with spars that fly at an angle to the mast. It is an ancient sailing rig that was extremely common in the early days of civilization, and it served workboats across the world for centuries.

Are Shorter Masts Stronger?

Short masts can be stronger, but they aren't always. It depends on the design of the craft and is more dependent on rig type than the size of the mast itself. The strongest masts are found on gaff-rigged vessels. They are usually short and thick and traditionally made of wood.

The strength of the mast isn't so important when everything is working properly. It begins to matter in the event of a failure, like a broken stay.

A gaff-rigged vessel with a typical mast has a good chance of surviving a snapped stay as the mast can support itself. A Bermuda-rigged vessel, more likely than not, could lose its mast immediately after the standing rigging goes down.

What are Masts Made Of?

Masts are made of many different materials. Traditionally, wood was the mast material of choice. It was strong and lasted a very long time if maintained. Through the production sailboat era, when boatbuilders switched from wood to fiberglass for hulls, sailboat masts were mostly made of aluminum.

Today's high-tech racing sailboats have many more options to choose from. Composite materials, such as carbon fiber, are increasingly common due to their astounding strength-to-weight ratio. Alloy masts are also fairly common. Steel masts exist, but their use is usually confined to small sailboats and dinghies.

How Tall Are Sailboat Masts? 9 Examples

The mast height of a sailboat varies with every model.

So what determines the height of a mast?

Here’s How Tall Sailboat Masts Are:

As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.

Table of Contents

Understanding a Sailboat’s Mast and Rig

Sailboats are driven through the water by the power generated by their sails.

This is done using sail area. Sail area is calculated using the height of the mast and the length of the boom.

The battens, long strips of wood inserts in the sail, allow more sail area as they extend beyond a straight line from the head of the mast to the back of the boom, thus allowing more cloth to be carried.

Keep in mind that the mast height does not equal the luff length of the main; there is a distance between the deck and the top of the boom.

Most mains do not go all the way to the top of the boom mast.

Wind Gradient:

Designers are also aware of the wind gradient, meaning that as the wind blows over the water, the surface causes drag.

So the breeze is stronger the higher you get off of the surface.

Taller masts allow you to reach these stronger winds.

Mast Height:

While mast height is a prime determinant in the area, it is also possible to make a mast too tall so that the boat is always in danger of taking a knockdown.

Note there are some performance boats designed with masts that are too tall for the craft’s weight, assuming that the weight of the crew will balance out the sail area.

One thing to bear in mind here is a rig’s aspect ratio: this is determined by dividing the designed sail’s luff length by the length of the foot. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.

Higher aspect boats perform better upwind; lower aspect ratios generally are more powerful in other wind conditions and are usually easier to control.

What’s the Average Height of Sailboat Masts?

Sailboats can range from 6 feet to a hundred or more feet in length if you throw out the multi-masted sailing ships of old.

The mast height for every single one is different.

The height of a mast is usually carefully calculated by figuring the amount of power needed to move a certain hull shape and weight through the water. In many cases, in the 1960s through the 1980s, some designers went by feel.

A few boatbuilders would use the same mast across several of their models to save money in some cases.

As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat.

So, if you were going to average the mast heights of all 20-foot boats, you’d have about a 26-foot high mast and about 39 feet on 30-foot boats.

Boats built solely for cruising, particularly in offshore winds, will have shorter masts, and performance boats will have taller masts.

How do you Determine the Height of a Sailboat Mast?

Several factors determine a sailboat’s mast height.

A performance boat will have a higher aspect ratio for its sails and thus have a taller mast. Cruising boats will generally have smaller masts for the same length of the boat.

A wider and heavier boat than another boat will need more power to move it, so it will usually have a taller mast. If this heavy boat is a low-aspect-ratio rig designed for offshore work, it will probably have a comparably shorter mast for ease of handling in higher winds.

Conversely, a racing boat will be lighter but still have a taller mast to generate maximum power upwind.

Boats built for maximum performance will have very tall masts for their length and be very difficult to handle for an inexperienced crew – and sometimes for a trained, experienced crew as well, as the difficulties some of America’s Cup boats encounter demonstrate.

• The Melges 24 is a performance racer with a mast height of 31.4 feet for a head-to-head comparison. Her mainsail’s luff length is 28.92 feet, and the foot is 12.45 feet; she is a high-aspect-ratio boat.
• The Islander 24 has a mast height of 28.82, so it is 2 and 1/2 feet shorter than our Melges. The main’s luff length is 25.75 feet, and the foot is 11.52, for a low aspect ratio and much smaller main.
• The Islander 24 weighs 4,200 pounds, while the Melges 24 weighs less than 1,800 pounds.

How Tall is the Mast on a 40 ft Sailboat?

If a yawl or other rig with multiple masts, it will have shorter masts than a sloop.

If the boat is a fractional rig with a small foretriangle, like a modern high-aspect-ratio Hunter, the mast will be taller than another sloop of the same length:

• The old Tartan 40, an all-around great Sparkman & Stevens design from 1984, has a 51-foot mast. This is a classic racer/cruiser.
• The Nordic 40, designed around the same time, has a 52-foot mast.
• The Canadian-built C&C Crusader, designed in 1968, has a mast of 48 feet, but their later Mark 2 designs have masts of 53 to 55 feet in height.

These are all sloops. Ketch and yawl rigs will have masts shorter than this, as the smaller mizzens provide power (and helm balance).

So, this shows us that mast heights will fall into a range for any given length of the boat, again depending on other factors such as its function (primarily racing or cruising).

What is the Optimal Height of a Sailboat Mast?

As specified earlier, the designed height of a mast for any given sailboat generally falls between 1.25 and 1.35 times its length overall (as opposed to its waterline length).

The optimal height will be based on the designer’s calculations of the sail area and aspect ratio needed for the boat’s intended purpose. Beyond the simple racing/cruising divide, there are inshore and offshore cruisers and casual and serious racers.

Inshore cruising boats will generally be designed for maximum safety, and the mast height may be less than 1.25 times the length. Offshore cruisers may also be divided into casual and serious distance cruisers; a boat designed for better offshore cruising performance will have a taller mast.

It is unusual to find many cruising boats with a higher ratio than 1.3, however.

Racing boats will usually have a 1.35 ratio, though it can be as high as 1.5 or even higher at the extremes of the sport.

The mast height for America’s Cup AC50, a 50-foot catamaran, is 77 feet.

How Tall is the Tallest Sailboat Mast?

Two boats are currently competing for the title of having the world’s tallest mast.

Mirabella 5, now named M5 and launched in 2003, is the largest single-masted yacht ever built at 294 feet long.

Her mast is over 290 feet high.

The boom is nearly 90 feet in length. The mainsail has an area of 16,000 square feet! Her reacher (a large, light-weight genoa with some characteristics of a spinnaker), at 20,600 square feet, is the world’s largest sail.

The White Pearl, the world’s largest sailing yacht at nearly 350 feet, was launched in 2014. She has three carbon-fiber wing-style masts that are a little more than 90 meters high.

This puts the masts for the two yachts within a few feet of each other, though White Pearl gets the nod.

What to know more about the mini 650 class?

The Mini 6.50 Class is divided into production boats and the prototypes.

Some rules are common to all boats: 6.5m LOA max, 3m beam max, no communication, etc.

Prototypes are allowed to have daggerboard, canting keels, ballasts, carbon mast…etc. The mast is also a bit taller (11m instead of 10m for the production boats), the keel a bit lower (2m instead of 1,6m).

Let me introduce you to Kiraucassis.

She is a Maxi 650 from IDB Marine shipyards in France.

She is 6.5m (21ft) of raw power, built to cross oceans really (really) fast, single-handedly.

On my first day test sailing her, we would already reach 17+kts

She has a rounded bow, a design called "scow".

Many say it’s ugly, some love this… in my opinion, it makes her faster than the competition when reaching and downwind… that’s all I’m asking for.

Find out more about the design in my vlog.

the next boat to race single-handed across the Atlantic?

My next project is to race the Mini Transat, a race across the Atlantic single-handed on a one-design fleet.

The Mini 6.50 class is an incubator for innovation. Most of the technology and design concepts you find today in the IMOCA class have first been tested (and crash-tested) on a mini.

I chose to go for a scow, more powerful and stable downwind, the Maxi 650, from IDB marine, see more specs  here.

Can’t wait to get on the water with this new toy to see what it can give. Until then, have a look at the surfs these tiny offshore beasts are capable of.

• Navigating the High Seas: A Comprehensive Guide to Sailboat Masts

Sailboat masts are the unsung heroes of the sailing world, silently supporting the sails and ensuring a smooth journey across the open waters. Whether you're a seasoned sailor or a novice, understanding the intricacies of sailboat masts is essential for a safe and enjoyable voyage. In this comprehensive guide, we will delve into the world of sailboat masts, discussing their types, maintenance, and everything in between.

Types of Sailboat Masts

Sailboat masts come in various configurations, each with its advantages and drawbacks. The two primary types are keel-stepped and deck-stepped masts.

Keel-Stepped Masts

Keel-stepped masts are the most common type, extending through the deck and resting on the boat's keel. They provide excellent stability and are suitable for larger sailboats. However, they require careful maintenance to prevent water intrusion into the boat's cabin.

Deck-Stepped Masts

Deck-stepped masts rest on the deck of the boat, making them easier to install and remove. They are commonly found on smaller sailboats and are more forgiving in terms of maintenance. However, they may offer slightly less stability than keel-stepped masts.

Components of a Sailboat Mast

To understand mast maintenance better, it's essential to know the various components of a sailboat mast. The key parts include the masthead, spreaders, shrouds, and halyard sheaves.

The masthead is the topmost section of the mast, where the halyards are attached to raise and lower the sails. It also often houses instruments such as wind indicators and lights.

Spreaders and Shrouds

Spreaders are horizontal supports attached to the mast to help maintain the proper angle of the shrouds (cables or rods that provide lateral support to the mast). Properly adjusted spreaders and shrouds are crucial for mast stability and sail performance.

Scallywag First to Finish Transatlantic

• By James Boyd
• Updated: July 8, 2019

Lee Seng Huang’s 100-foot maxi SHK Scallywag entered the history books by winning line honors in the Transatlantic Race 2019. This accolade continues a prestigious, ancient lineage started by James Gordon Bennett Jr.’s Henrietta in 1866 and since including Charlie Barr on Wilson Marshall’s record setting three-masted schooner Atlantic in 1905 to a century later, Robert Miller’s Mari Cha IV, winner of the Rolex Transatlantic Race in 2005. The New York Yacht Club organized the first race in 1866 and this year was joined by the Royal Yacht Squadron, Royal Ocean Racing Club and the Storm Trysail Club.

The Andy Dovell-designed maxi crossed the Royal Yacht Squadron line off Cowes with a passage time of 10 days, 2 hours, 13 minutes and 19 seconds. Skippered by David Witt, the Australian now living in Hong Kong, SHK Scallywag ‘s crew included Anniemeike Bes (Haarlem, the Netherlands), Lucas Chapman (The Junction, Australia), Tom Clout (Sydney, Australia), Nick Crones (Sydney, Australia), Pete Cumming (Warsash, U.K.), Ian Flemming (Hong Kong), Ferdinand Galleta (Bauang, Philippines), Alex Gough (Brisbane, Australia), Jack Mcartney (Paddington, Australia), Ben Piggott (Thirrol, Australia), Trystan Seal (Cilcennin, Wales), Miles Seddon (Lymington, U.K.) and Charlie Wyatt (Brisbane, Australia).

If there were any records for this year’s race it was for the slow pace as the leaders found themselves having to take dramatic detours to avoid windless high-pressure systems. In the race’s last edition in 2015 Jim and Kristy Clarke’s 100-foot maxi Comanche won line honors in 7 days, 11 hours, and 35 minutes, and that was also considered a relatively slow race.

For skipper Witt, a modern-day Samuel Samuels (Gordon Bennett’s skipper in 1866), the concern was making it across. “It comes with some relief. At one point it didn’t look like we were going to make it,” Witt said.

Shortly after rounding A3, the southeastern-most point of the Point Alpha ice exclusion zone, SHK Scallywag found herself nailed by prolonged gale force winds. As British navigator Miles Seddon describes: “The sea state wasn’t that bad, it was probably 2 to 2.5 meters (six to eight feet) with the occasional 3-meter wave (nine feet), but we just got caught too close to the center of the low, between the cold front closing up on the warm front. The forecast was for 25 knots max and we were prepared for gusts of probably 32, but there we were, sailing along in 42. In 42 knots things are flying around the boat and you end up on the back foot because things get damaged.”

The crew couldn’t reef the mainsail beyond the second reef point because a bolt at the top of the towering, 41-meter (134-foot) mast had started to protrude and was preventing the crew from reducing sail beyond the second reef point.

“A $3 bolt almost destroyed a $3 million mainsail,” Witt said.

Under normal circumstances they might have turned and run with the gale to reduce apparent wind, but this would have taken them into the ice exclusion zone. “We were on the ice gate, it was like being pinned to a lee shore,” observed Witt.

Unwilling to retire, all they could do in the circumstances was to go into survival mode and sail with the main feathering until the severe winds passed. Thus, the SHK Scallywag crew battened down hatches, left two people on deck and rather than follow the big wind, let them move away. According to Witt the gale force winds lasted for almost 18 hours, but it was almost another three days before the wind had reduced enough, to 10 to 12 knots, for them safely to haul someone to the top of the giant spar and release the sail.

“It has been good for us,” Witt said generally of his Transatlantic Race 2019 experience. “The biggest problem with a 100-footer is reliability. The 70s [he refers to their competition, the VO70 Wizard , which previously won the Volvo Ocean Race as Groupama 4] have been around the world. The longest race 100-footers typically do is the Sydney to Hobart, which is 600 miles.” The Transatlantic Race 2019 was by far SHK Scallywag ‘s longest race to date.

During the big winds SHK Scallywag also damaged her largest jib, the J1 when it was washed overboard while hanked on. This incident also destroyed some of the forward stanchions. According to Seddon they also took some waves that caused their tracker to become water-logged and inoperable and they also temporarily wiped out their satellite communications, although they subsequently managed to repair this.

Once back up to speed SHK Scallywag was able to make good use of the conditions prior to negotiating the top of the high pressure. In this period their top 24-hour run was 505 miles.

Witt paid tribute to the Wizard crew, who against expectation (due to having a 30-foot shorter boat) led for the majority of the Transatlantic Race 2019. “They will win under IRC and they deserve to win that. You have to realize that in 40-plus knots, you’d much rather be on a VO70. We were lucky we didn’t give up. It was only when the breeze dropped that we could catch up,” said Witt.

For Seddon, this year’s slow race came after a comparatively rip-roaring ride across four years ago on the 70-foot trimaran Phaedo in a time of just over seven days. “It is very nice to be here,” he said upon finishing. “It felt like it went on for longer than eternity! We tried to throw it away a few times. It was beautiful sailing conditions to begin with, heinous survival mode in the middle and playing catch up again. It was certainly a long one.”

Back up in fighting mode, SHK Scallywag eventually passed Wizard for a second time approaching the Scilly Isles and then basked in the light upwind conditions of the last 48 hours when they could make full use of their towering sail plan and their waterline length advantage.

SHK Scallywag dealt with an ultra-light-wind English Channel and its present strong tides remarkably well. “The only time we got slowed down was between Portland Bill and Anvil Point,” explained Seddon. “The change of tide killed the wind and the cloud cover stopped the sea breeze from developing. So we had to wait, anchor at the ready.” In fact in the half hour it took for them to ready the anchor, the first signs of a new breeze filling in were already evident.

This afternoon there was enough wind to get them through Hurst Narrows at the western end of the Solent despite their having to punch into 4.5 knots of adverse current. “In 8 to 10 knots of wind we are doing 13 knots through the water, so it didn’t affect us too badly. We knew we’d get through it,” said Seddon.

Sailboat Mast: A Comprehensive Guide to Understanding and Maintaining

by Emma Sullivan | Jul 14, 2023 | Sailboat Maintenance

== Short answer: Sailboat mast == A sailboat mast is a vertical pole or spar that supports the sails of a sailboat. It provides structural stability and allows for adjustment of the sail position to effectively harness wind power. Typically made of aluminum or carbon fiber, mast design varies based on boat size, sailing conditions, and intended use.

The Sailboat Mast: A Comprehensive Guide for Beginners

Title: The Sailboat Mast: A Comprehensive Guide for Beginners

Introduction: Ah, the majestic sailboat mast! Like the beating heart of a ship, it stands tall and proud, guiding us through the vast ocean. But what does it actually do? How does it work its magic to harness the power of wind and propel us across water? In this comprehensive guide for beginners, we’ll dive deep into the world of sailboat masts to unravel their secrets and discover why they are indeed a sailor’s best friend.

1. Anatomy of a Sailboat Mast: To understand how a sailboat mast functions, let’s start by dissecting its anatomy. The mast consists of several essential components such as: – Luff track: This vertical groove allows the mainsail to slide up or down smoothly. – Spreaders: These diagonal bars help strengthen and stabilize the mast. – Shrouds and stays: These supportive cables hold the mast in position while also countering sideways forces. – Sheave boxes: Found at strategic points on the mast, these small wheel-like mechanisms assist with hoisting sails or other rigging tasks. By familiarizing ourselves with these various parts, we can appreciate how each plays a crucial role in maintaining balance and stability.

2. Materials Matter: Masts can be constructed from different materials including wood, aluminum alloy, carbon fiber composite, or even stainless steel. While wooden masts exude classic charm, modern technologies have introduced lighter options like carbon fiber that enhance performance and durability. The choice of material depends on factors such as boat size, sailing purpose (racing or cruising), budget constraints, and personal preferences.

3. Setting Sail: Hoisting Techniques Hoisting your sails is an art in itself – a symphony between wind and rigging systems. When raising your main sail, you can rely on either external halyards run externally to pulleys at deck level or internal halyards hidden inside the mast. The former allows for easy maintenance and inspection, whereas the latter provides a sleeker aesthetic appeal. Whichever method you choose, proper hoisting techniques are crucial to avoid tangling or jamming.

4. Sail Control: Mast Dynamics Understanding how the sail interacts with the mast is essential for optimizing performance. Controlling sail shape is achieved through tensioning and releasing various lines such as halyards, cunninghams, and outhauls. These adjustments influence mast bend, which in turn affects the distribution of power and aerodynamic efficiency of your sails. A well-tuned mast ensures efficient sailing in different wind conditions.

5. Stepping Up: Installing a Sailboat Mast Stepping a mast may provoke anxiety among beginners, but fear not! With careful planning and some assistance, it can be an invigorating part of preparing your sailboat for action. From proper alignment to securely attaching shrouds and stays, following step-by-step procedures helps avoid mishaps during this critical process.

6. Maintenance Matters: Regular maintenance extends the lifespan of your sailboat mast while ensuring safety on the water. Frequent inspections for corrosion, cracks, or loose fittings are essential. Additionally, lubricating moving parts like sheaves and checking tension in standing rigging help guarantee smooth sailing adventures.

Conclusion: Congratulations! As you reach the end of this comprehensive guide on sailboat masts, you’ve gained invaluable insights into their anatomy, materials used in construction, hoisting techniques, dynamics correlation with sails – all topped off with stepping tips and maintenance reminders. Now equipped with this knowledge foundation, novice sailors can embark confidently upon their seafaring journeys armed with an understanding of just how crucial the majestic sailboat mast truly is – a steadfast partner harnessing wind power while propelling us towards endless maritime horizons!

How to Choose the Perfect Sailboat Mast for Your Vessel

When it comes to sailing, one of the most crucial components of your vessel is undoubtedly the sailboat mast. It serves as the backbone and lifeline of your boat, allowing you to harness the power of the wind and navigate through the vast open waters. Choosing the perfect sailboat mast is not a decision to be taken lightly; it requires careful consideration of various factors to ensure optimal performance and safety.

Firstly, before delving into the specifics, it’s important to understand that sailboat masts come in different materials, each with its unique set of characteristics. The most common options are aluminum and carbon fiber. While aluminum masts offer durability at a lower cost, carbon fiber masts are lighter and stiffer, providing enhanced performance on the water.

Now let’s embark on our journey to select the ideal sailboat mast for your vessel! The first crucial factor to consider is your boat’s size and weight. A larger, heavier vessel would require a mast with greater strength and rigidity to withstand increased loads from larger sails. On the other hand, smaller boats may benefit from a lighter mast that allows for more flexibility in sail adjustments.

Next up is understanding your sailing goals – are you more inclined towards leisurely cruising or competitive racing? If you’re an avid racer seeking top-notch performance, a carbon fiber mast might be your best bet due to its stiffness and superior response to wind conditions. However, if you prioritize comfort and relaxation during casual sailing trips, an aluminum mast could provide suitable stability without compromising on enjoyment.

Another aspect not to be overlooked is ease of maintenance. Aluminum masts generally require less upkeep compared to their carbon counterparts as they are less prone to damage from UV rays or accidental impacts. Carbon fiber masts demand regular inspection for any signs of wear or stress fractures since they can’t handle excessive bending or compression forces as well as aluminum.

Moreover, think about where you’ll primarily be sailing – will it be in open, unrestricted waters or areas with low bridges and height restrictions? Mast height plays a significant role here. Ensure your chosen mast fits within the clearance limits to avoid any unpleasant surprises during your journeys.

Sailboat masts come in various configurations, including single-spreader, double-spreader, and even triple-spreader setups. The number of spreaders – horizontal struts that help support the mast – affects overall stability and rigging options. Generally, single-spreader masts are easier to handle for casual sailors, while double or triple spreads offer higher performance but demand more meticulous tuning.

Lastly, it’s worth noting that the perfect sailboat mast doesn’t necessarily mean splurging on the most expensive option available. A comprehensive comparison of prices and features from different manufacturers can lead you to an ideal balance between affordability and quality.

At this point in our mast-selection odyssey, you should have a clearer picture of what to consider when choosing the perfect sailboat mast for your vessel. Remember to evaluate factors such as materials (aluminum vs. carbon fiber), boat size/weight, sailing goals (cruising vs. racing), maintenance requirements, clearance restrictions, spreader configuration, and cost-effectiveness.

Now set sail confidently with a mast tailored precisely to meet your vessel’s needs and embark on countless unforgettable nautical adventures! Bon voyage!

Are you a sailing enthusiast who has always been fascinated by the graceful movement of sailboats gliding through the water? Do you dream of owning your own sailboat and embarking on exciting adventures in the open sea? If so, then one of the essential skills you need to acquire is how to install a mast on a sailboat. In this beginner’s guide, we will walk you through the process step-by-step, ensuring that even if you have never done it before, you will be able to tackle this task with confidence and expertise.

1. Tools and Preparation: First things first – gather all the necessary tools for the job. You will need a crane or hoist (if available), a torque wrench, mast wedges, shims, sail track lubricant, an adjustable wrench or socket set, and plenty of patience! Before starting the installation, ensure that both your boat deck and mast are clean and free from dirt or debris.

2. Preparing the Mast Step: The mast step is where your mast rests on your boat deck. Start by inspecting it thoroughly for any damage or wear that may compromise its integrity. If needed, reinforce or repair it before proceeding further. Place mast wedges under the front part of the mast step to act as support when installing.

3. Attach Necessary Fittings: Now it’s time to attach various fittings onto your mast which are crucial for rigging control lines and sails effectively. These include halyard sheaves (for raising and lowering sails), spreader brackets (providing horizontal support), and any other attachments specific to your sailboat model.

4. Hoisting with Precision: Here comes the exciting part – hoisting your sailboat mast into position! Ideally, use a crane or hoist designed explicitly for this purpose so that you can easily control its vertical movement while minimizing the risk of damage. Carefully guide the mast toward the mast step, ensuring it is centered and aligned correctly.

5. Adjusting for Precision: Once your mast is in place, it’s time to make fine adjustments to ensure its vertical alignment. Use shims or wedges as necessary to eliminate any gaps between the mast and mast step. This step is crucial as it ensures that your sailboat will perform optimally on the water without any unnecessary stress on either the mast or your rigging.

6. Securing with Confidence: Now that your mast is perfectly aligned, it’s time to secure it in place. Start by cautiously tightening the bolts on each side of the base using an adjustable wrench or socket set. Remember not to overtighten, as this can potentially damage both your boat and mast. Once done, check all fittings once again and confirm they are securely attached.

7. Lubrication for Smooth Sailing: To ensure flawless movement of your sails along the track, apply a suitable sail track lubricant generously over your sail track after installation while closely following manufacturer guidelines. This lubrication will minimize friction when hoisting or lowering sails, resulting in a smoother sailing experience overall.

A sailboat mast is essentially a vertical structure that stands tall and proud on a vessel, supporting the sails and imparting stability to your seafaring adventure. Think of it as the backbone upon which your nautical dreams come to life!

2. Why is choosing the right mast crucial for efficient sailing? Picture this: you’re in command of your trusty sailboat, ready to conquer the sea’s vast playground. But alas! Your hasty choice of an ill-suited mast has left you floundering like a fish out of water! The right mast offers optimal rigidity, balance, and strength necessary for efficient navigation regardless of wind conditions or sea state.

3. Aluminum or carbon fiber? Which material reigns supreme for masts? Ah, here lies one’s decision-making predicament! Does one opt for aluminum – sturdy like an old lighthouse but slightly heavier? Or does one embrace carbon fiber – lightweight as an albatross feather yet remarkably robust? Both materials have their merits; therefore, choosing between them boils down to personal preference and intended usage.

4. Can I upgrade my existing mast without breaking the bank? Fear not, fellow mariner! While pursuing that luxurious upgrade might conjure images of treasure chests filled with gold doubloons disappearing into Davy Jones’ locker, there are cost-effective options available. Opt for used masts in good condition, or explore local sailing communities where fellow sailors may be willing to part with their old but serviceable masts.

5. How can I ensure proper maintenance of my sailboat mast? Ahoy, matey! Maintenance is the key to keeping your mast shipshape and preventing any unwanted surprises on your voyage. Regular inspections for cracks, corrosion, or loose fittings are akin to swabbing your deck – tedious yet necessary. Additionally, ensuring proper storage and protecting your mast from harsh elements will keep it standing tall through the test of time!

6. Can a damaged mast be repaired or must it walk the plank? Nay, despair not as all hope is not lost! In cases of minor damage like small cracks or dings – worry not! Reliable craftsmen specializing in mast repairs can work their magic and have your trusty companion primed to conquer the waves once more. However, in more severe instances of structural compromise, replacing the mast might be the only option left.

7. How do I decipher the mysterious language of sailboat mast measurements? Approach ye with careful study, for understanding these mystifying dimensions requires an astute mind! Height measured from deck to tip (known as height aloft), length along its backside (called luff measurement), and even diameter play a significant role in determining compatibility with your vessel’s rigging system. Consult experts fluent in this ancient tongue to avoid any discrepancies on your nautical journey!

In summary, sailboat masts are no mere aesthetic addition; they are essential components that provide stability and sailing prowess to vessels at sea. Choosing the right material and maintaining them diligently ensures smooth sailing adventures without scuppering one’s budget. So set your sights high, dear reader, for these answers shall guide you towards a more enlightened understanding of sailboat masts!

Important Factors to Consider When Maintaining Your Sailboat Mast

Sailing is a thrilling and invigorating experience that allows us to connect with nature, challenge ourselves, and explore the vast open waters. However, as with any adventure, there are certain aspects that we must pay close attention to in order to ensure a safe and successful voyage. One such critical component of a sailboat that demands careful maintenance is the mast. The mast serves as the backbone of your vessel, providing structural integrity and supporting your sails. In this blog post, we will delve into some important factors to consider when maintaining your sailboat mast.

Structural Integrity: The first and foremost factor that you need to consider when maintaining your sailboat mast is its structural integrity. Any signs of damage or wear and tear should not be taken lightly, as it can compromise the overall stability and safety of your vessel. Regularly inspecting your mast for any cracks, dents, or corrosion is crucial to identify any issues early on before they escalate into major problems. Additionally, keep an eye out for loose or rusted fasteners and make sure all connections are secure.

Rigging Wear: Another vital aspect of keeping your sailboat mast in top condition is paying attention to its rigging components. Rigging includes various cables, wires, and ropes responsible for controlling the sails’ position and tension. Over time, these elements can experience significant wear due to exposure to sun, saltwater, intense winds, or simply general usage. To maintain rigging longevity and ensure safety while sailing, regularly examine all parts for fraying strands or broken wires. Furthermore, proper tensioning of rigging should be maintained as per manufacturer recommendations.

Cleanliness: Maintaining a clean sailboat mast may sound like an obvious consideration but is often overlooked by many boat owners. A dirty mast not only affects the aesthetics but can also lead to performance issues if left unattended for too long. Accumulated dirt, grime, salt deposits or marine growth can create unwanted drag, hindering the sailing experience. Regular cleaning with mild soapy water and a soft brush is generally sufficient to remove stubborn stains and prevent corrosion.

Painting: Maintaining the aesthetic appeal of your sailboat mast should also be on your priority list. A fresh coat of paint not only enhances its appearance but also offers added protection against corrosion. Prior to painting, ensure that the mast is thoroughly cleaned and all rust or peeling paint is removed. Use a high-quality marine-grade paint specifically designed for aluminum or wooden masts, depending on the material of your sailboat’s mast.

Inspections: Performing routine inspections by a professional is an essential factor in maintaining your sailboat mast. It is recommended to have an experienced rigger thoroughly inspect your mast at least once a year, or more frequently if you actively engage in competitive racing or regularly navigate harsh conditions. These experts have the knowledge and expertise to identify potential weaknesses that may go unnoticed by untrained eyes, providing peace of mind and preventing any unexpected mishaps on your sailing journeys.

In conclusion, maintaining your sailboat mast requires careful attention to detail and regular inspections. By prioritizing factors such as structural integrity, rigging wear, cleanliness, painting, and professional inspections, you can ensure that your vessel remains in excellent condition for countless captivating voyages ahead. So set sail with confidence knowing that you’ve taken every measure to maintain this vital component of your beloved sailboat!

Discover the Different Types of Sailboat Masts and Their Advantages

Sailing is an activity that combines the thrill of speed with the serenity of the open water. One crucial component of any sailboat is the mast, which not only provides structural support but also plays a vital role in determining a boat’s performance and handling characteristics. To help you dive deeper into this fascinating world, we will explore the different types of sailboat masts and highlight their advantages.

1. Fractional Masts: Let’s start with fractional masts, which are one of the most common types found on sailboats today. As the name suggests, these masts divide the rig into two sections: upper and lower. The ratio of the length between these sections can vary, offering flexibility depending on sailing conditions and desired performance.

Advantages: – Versatility: Fractional masts allow for fine-tuning your sails by adjusting halyard tension or configuring additional stays. – Better control in strong wind conditions: The longer lower section provides stability and prevents excessive heeling (tilting) usually encountered during high winds. – Improved balance: By placing more weight aloft, fractional masts offer better balance when tacking (changing direction against the wind).

2. Masthead Masts: In contrast to fractional masts, masthead masts have their forestay attached at or near the masthead rather than a fraction down its length. Traditionally seen on older cruising boats, they offer distinct advantages for particular sailing styles.

Advantages: – Strong downwind performance: With their design allowing for larger headsails like genoas or asymmetrical spinnakers, masthead rigs excel in reaching or downwind courses. – Easy to balance for autopilot usage: Due to a greater proportionality between mainsail area and foresail area when compared to fractional rigs, mastheads tend to require less manual adjustment while under autopilot control.

3. Keel-stepped vs Deck-stepped Masts:

3.a. Keel-stepped Masts: Keel-stepped masts are secured and supported by the boat’s keel, extending through the deck to connect with it at the base. This type of rig is commonly found on larger sailboats designed for offshore sailing.

Advantages: – Superior strength: The keel provides excellent support for the mast against heavy loads encountered during rough weather conditions. – Reduced deck compression: By transferring the load directly to the keel, stress on the deck is minimized, ensuring a longer-lasting and more reliable structure overall.

3.b. Deck-stepped Masts: Deck-stepped masts sit on top of a sailboat’s deck, rather than being connected directly to the keel. Typically seen on smaller boats and cruising vessels, they have their own set of advantages.

Advantages: – Easier maintenance: With no penetration through to the hull like keel-stepped masts, maintaining or replacing deck fittings becomes less complicated. – Cost-effective construction: As there is no need for precision alignment with a keel box, constructing a boat with a deck-stepped mast can reduce building costs. – Adjustable height: Deck-stepped masts offer flexibility in terms of adjusting their height based on clearance requirements for bridges or overhead obstructions.

Understanding these various types of sailboat masts empowers sailors to make informed choices when selecting or upgrading their vessel’s rigging. Each mast type brings its own set of advantages that can significantly impact your sailing experience depending on different conditions and preferences.

Sailboat Mast Height

You see this – what do you do? What should you have done?

Last week, Editor and Chief of Sail Magazine, Peter Nielsen, and I chartered a 38 foot catamaran from the local Moorings Base in the Bay of Islands, New Zealand, on a bareboat yacht charter. Peter was writing a story about sailing in the south pacific which will come out later this year (keep and eye out for it). We snapped some great shots, did some great sailing, caught lots of snapper and ate like kings in some of the most beautiful bays. The Kiwi weather really turned it on for us and the New Zealand Tourism board will be happy as Peter had a great time and surely will be writing up the Bay of Islands as a must see sail area.

So we sailed up into the Kerikeri inlet to the north of Moturoa island and past the stunning Black Rocks – where in the old days whales were so abundant here that whalers used to harpoon the whales from these rocks.  The wind was 20 knots out of the north so it made for a nice beam reach into the inlet. On the way back we decided to do a run through the Kent Passage. About 100 meters back I noticed power wires crossing from the mainland to Moturoa Island.

Kerikeri Inlet – Bay of Islands New Zealand

“Hmmmm”, I said to Peter “what do you think about those”.

“Hmmmm” replied Peter.

We both looked at the GPS which noted nothing on the electronic chart.

A quick consult of the paper chart showed the following image with a very hard to see thin line.

Not much information and no height datum.

“Hmmmm” we both said

We could now see a sign on the shore warning of the DANGER. But we could not read the specifics.

“Hmmmm” one more time. 30 meters to go!!!!!

With out any more hesitation and with prudence taking over, we brought the boat up into wind, turned on the engines and motored the boat away from the lines.

We got out the binoculars and were able to see the sign marking which indicated 23 above MHHW.

From the manual in the chart table, the sailboat mast height above the water line on a Leopard 38 is 19.1 m. That made it safe to proceed.

MHHW is the mean higher high water. This is the average height of the high tide during spring tides. Bridges and power wires are marked as such to indicate safe passage at these times. This is opposed to chart datum depths which are marked as MLLW.

So the lessons learned here:

• If you’re unsure of situations like this bail out. We did the right thing. Not that we were under any time constraint, but there is no time constraint that is worth really messing up like what could have happened.
• Know your sailboat mast height. When pilots get rated for an aircraft they spend hours and hours studying the characteristics of an aircraft. Yet when we go charter a boat – at best the Yacht Charter Base will spend maybe an hour with you.

Off the top of my head, here’s a list of boat characteristic specifications that you should know about when chartering a Sailboat on a Bareboat Yacht Charter sailing holiday .

• Sailboat mast height
• Offset of the depth meter (some charter companies add in a 5 ft offset below the keel, some do it at the keel, some do it at the water line and some don’t even know)
• Beam Width (for unfamiliar marinas)
• Number of water tanks
• Max cruising revs for engines
• Boat speed at max cruising revs
• Length of anchor rode
• Reefing wind speeds

Typically, you’re not going to be too concerned about fuel capacity with a week to 10 day long yacht charter, but it’s prudent to watch fuel usage.

There is a lot of other things to learn about a charter boat like locations of safety gear etc. But this is more about the boat dimensional characteristics.

I’ll end the post with a bit of humor.

How To Climb A Mast Solo And Short Handed

• June 1, 2022

Learn how to climb your mast solo or short handed and head aloft with confidence with this step by step expert guide from Pro Skipper and Tech Ed Fox Morgan

How to climb a mast solo: Step by step guide

If you’re here because you want to know how to climb a mast, then you are in the right place! The technique demonstrated in the following guide is tried and tested and used by the majority of professional sailors and expert Corinthian sailors too. This is for people climbing a mast where the halyard runs internally and passes out of the mast at the mast head via a mast head sheave or block. This technique is not intended for those climbing a wooden mast or where the halyard is mounted externally and passes via an external block. If you are unsure of any aspect of safety when doing any kind of work at height, please consult a local rigger.

It can feel quite lonely up a mast with no-one to spot you from below. But it’s also a really nice feeling to be able to get the job done.

Solo Mast Climbing Technique

• Wear appropriate clothing. We recommend close fitting clothing that wont snag on anything. Also protect your shins.
• Consider wearing body armour if going up the mast at sea. It’s very easy to be slammed against the mast and crack a rib, which will definitely spoil your day.
• Wear a helmet if you are in a rolling anchorage or underway. A BMX, kayak or dedicated climbing hard shell helmet is ideal.
• You should be fit enough to be able to lift your own weight with one leg in a foot strap and one arm on an ascender.

• Attach 2 halyards to the mast foot area.
• Attach prusik line to the halyard or line you are using as a backup safety.
• Attach Ascender and GriGri to the main working line/halyard.
• Clip on harness.
• Double check all carabiner gates are locked closed and nothing is cross loaded.

How to climb a mast now you have all the equipment in place

• Slide the ascender as high as you can while standing.
• Pull up on the lazy line to pull the GriGri/belay device as far up the line as you can, as high as it will go while you stand on deck.
• Sit back into your harness and watch the GriGri articulate (if you are using this device) and see it grip the line.
• Make sure your foot is in the footstrap.
• Slide the ascender as high as you are able to.
• Grab hold of the ascender handle and pull yourself up so that you are standing in the footstrap.
• Take in the slack on the GriGri/belay device pulling it up the line as high as possible, to meet the bottom of your ascender.
• Sit back down again. watch the GriGri articulate again and watch for any snags or anything that doesn’t look right.
• Slide the ascender upwards again as far as you can.
• Repeat this process to rappel as far as you want up the mast.

Remember to keep sliding your prusik line up as you progress. This is your backup if the main line fails.

Ascend at your own pace.

You will swing about a bit. You can use your spare non-footloop leg to help grip the mast and steady you from swinging about too much. A couple of quick draws can be handy for holding you in place while you stop to work.

Beware of the need to leave a small gap above the ascender to allow it to be released from the line. So don’t go hauling it upwards slamming it into the underside of your masthead overhang. You’ve been warned!

When ready to descend, double check all of your lines and carabiners.

• Sit back on your GriGri or belay device, ensuring it holds you without slipping and remove the ascender from the line.
• Close the ascender gate to avoid getting spiked and hang it from your harness.
• Wind up the foot strap, tuck that away. You don’t need the footstrap anymore but you also don’t want it to get snagged on anything on the way down.
• With one hand on the lazy line,  ease back on the GriGri lever or belay device with the other hand to gradually release the friction on the line you are sitting back on.
• Feed the lazy line to control your speed of descent. You will start to slide down the line.

REMEMBER to slide your prusik line down as you go!

Take it slowly and control your descent carefully. There’s a lot to get snagged on as you go back down the mast.

Use your legs to grip the mast if the boat is moving around a lot.

How to climb a mast double handed

You have a few options.

• A harness combined with bosun’s chair for a lengthy time up in the air or just a harness for a quick trip.
• I prefer a hard seat bosun’s chair so I can sit back in it for a rest when doing lengthy jobs, such as feeding lines or wires down the mast. A harness is secure but can easily nip off circulation to a leg when hanging around for a long time. Foot loops can also help to take pressure off or allow you to gain a little height above the mast head.
• Agree on hand signals for up and down winding.
• Have your co-skipper wind on one winch while you slide a prussic line up the second secure line. Alternatively they could wind up one line then take up slack on a second winch with the safety line, as both can be attached to your bosun’s chair or harness, but this means your crew mate will be running between lines and this runs the risk of mistakes, cross winching, or tangles or worse, accidental line release. A prusik on a static line attached to mast foot while you are winched up on another line is a much safer method for two people.
• For security when you are working aloft, make sure your co-skipper locks off that line on the winch to either a cleat or double back to create a locking turn. Don’t just rely on a clutch.
• When they ease you back down the line, remember to hold your prusik line and knot as you go. This will help to hold you steady but also allow you to stop your descent quickly if you need to.

How to climb a mast fully crewed

Use two lines, one per winch and you have a lead wincher for the main number one line and a second line tailer, taking up the slack on the safety line.

If you have enough crew, have someone as a designated spotter to relay messages to the prime wincher.

• If you are unsure of the safety and condition of the lines, make sure you have a safety backup or mouse a new line through if there’s doubt over the condition of the line you are using. This might not be possible if you have a broken halyard already and the reason you’re going up is ton put a new one in!
• Always go up with two lines.
• Always wear footwear.
• Use padding and head protection if there is a risk of you swinging about with the boat in motion.
• Tie your own knot to your bosun’s chair or harness if being winched. Do not rely on the shackle or sail crimp to secure you.
• Lanyard on/secure all tools
• Use a mobile phone with hands free set or a pair of handheld vhf radios on ships internal comms channel 15 or 17 on low power/1w. [Calling protocol would be: Boatname – Alpha (for one person, eg up the mast) Boatname – Bravo (for another person, eg on deck spotting)]
• Make sure your comms devices are securely attached and cannot fall.

Spot the little faces looking upwards from the cockpit area. Your crew mates will seem quite far away when you are high up in the rigging. Make sure you have adequate communication in place for safety.

The bigger the boat, the more important comms devices become. Pace out the length of your mast on land, let’s say that’s 25m or 85 feet away away, now face sideways and try talking to someone at that distance. Rig up your phones or vhf radio on hand free use. Make sure comms devices are secured and can’t fall.

Don’t forget to use your own judgement when following our advice, or use a professional. Here’s our full disclaimer.

Petzl ascension ascender.

This is the ascender I use on my own climbing gear and can be seen in my demonstration on how to climb a mast. I use a left handed version because I am right hand dominant and it’s easier for me to slide the ascender up with my left hand while pulling up on the lazy line with my right hand.

For belaying and rappelling. It is designed for use with both single and double ropes.

I use two of these in my solo mast climb gear. One is used from the bottom of the ascender to hold the footloop and personal lanyard and the other is used on the top of the ascender to work as a reduction turning point for the belay lazy line.

You need to be careful which way around your position this on your ascender to avoid your lazy line accidentally unscrewing it as you pull it through.

Black Diamond Gridlock Screwgate Carabiner

Designed specifically for belaying, the GridLock isolates the belay loop behind its uniquely shaped gate, thereby keeping the carabiner in its proper orientation.

I use two of these carabiners, both from my harness. The anti-crossloading design is reassuring as the repeated loading and unloading of both the belay and ascender has a tendency to make standard carabiners rotate and there’s a high risk of crossloading when solo rappelling. They can be fiddly to get on and off but they add real peace of mind knowing how hard it is for these to cross load so you can just get on with climbing and dangling about up your mast.

• Anti cross load design

DMM –  Rhino Quicklock – Locking carabiner

For regular users of pulleys or GriGri like belay devices.

I use this carabiner on my prusik line. The horn stops the hitched on line sliding around the carabiner as it is repeatedly adjusted. The sprung loaded rotating gate release can be a bit of a fiddle to open but the advantage is that it can’t be accidentally unscrewed like the screw gate carabiners can.

DMM Dyneema sling

Dyneema has several advantages over traditional nylon webbing – it’s incredibly light and strong, less susceptible to UV degradation and is more abrasion resistant. I use this sling as my personal lanyard between harness carabiner and the ascender. You need to find a sling that can be adjusted to your own personal reach length. I double this one over to give me the correct length.

• 11mm Dyneema tape
• Strength: 22kN

Beal Nylon Sling

A basic Nylon loop, ideal for use on a multitude of climbing uses, I personally use this as my footloop. I have two of them. They are cow-hitched onto the bottom of my ascender, one is tucked away and the other used for climbing. When I reach working height I use the second loop to stand up with both feet or to wrap one around the mast. It’s very handy to have two of these.

What Is A Sailboat Mast?

A sailboat mast is one of the most defining features of a sailboat (along with the sails of course!) You can immediately tell that a boat is a sailing boat when you spot the tall mast sticking out of the hull.

But why do sailboats need a mast? Having lived on a sailboat for years now I’ve never really questioned the need for a mast. It’s such an integral part of the boat that I just sort of forget it’s there!

When our friends recently lost their mast due to a rigging failure it got me thinking – why do sailboats need a mast and what function (aside from holding up the sails) do they actually play. It turns out, quite a lot!

We’re going to dive into the fascinating world of sailboat masts, exploring different rigs, mast materials, and the different functions that masts play. It’s important stuff if you want to go sailing, and a lot of it I should have known sooner!

Why do sailboats need a mast, parts of the mast, what materials are masts made from, single mast rigs, sailboats with two masts, sailboats with three masts, how to look after your mast.

A sailboat mast is a vertical, upright structure that supports the sails of a sailboat. It is a crucial component of the boat’s rigging system and plays a key role in harnessing the power of the wind to propel the vessel. Typically located in the center of the boat, the mast extends upward from the deck or hull.

The height of the mast varies depending on the size and type of the sailboat, directly impacting the sail area and overall performance of the boat.

Together with the boom (a horizontal spar attached to the bottom of the mast), the mast allows sailors to control the shape and orientation of the sails, optimizing their efficiency in different wind conditions.

The design and configuration of the mast can vary depending on the type of sailboat, such as a sloop, cutter, ketch, or schooner.

Sailboats require a mast primarily to support the sails.

It holds the sails in an elevated position, allowing them to catch the wind effectively. Without a mast, the sails would lack the means to be raised and positioned to harness the power of the wind.

There are a few other important jobs that the mast plays:

Control and Manipulation of Sails: The mast, along with the boom (a horizontal spar attached to the mast’s lower end), enables sailors to control and manipulate the sails.

By adjusting the angle and tension of the sails through the mast, sailors can optimize their performance according to wind conditions and desired boat speed.

This control allows for maneuverability and efficient use of wind power.

Structural Integrity: The mast contributes to the overall structural integrity of the sailboat. It helps distribute the loads and forces exerted by the sails, rigging, and masthead components throughout the boat’s hull and keel.

The mast’s design and construction ensure stability and strength, allowing the boat to withstand the forces generated by the wind.

Attachment Points for Rigging: The mast provides attachment points for various rigging components, including halyards (lines used to raise and lower the sails), stays (wires or rods that support the mast in different directions), and shrouds (wires that provide lateral support to the mast).

These rigging elements are essential for properly tensioning the sails and maintaining the mast’s stability.

Height and Visibility: The mast’s height contributes to the sailboat’s visibility, allowing other vessels to spot it more easily, particularly when sailing in congested waters. The mast’s presence also serves as a visual reference for determining the boat’s position, orientation, and distance from potential hazards.

While the mast’s primary purpose is to support the sails and enable control over their position, it also plays a significant role in maintaining the structural integrity of the sailboat and enhancing its visibility on the water.

Basically, the mast is pretty darn important!

Along with a million other confusing sailboat terms , the mast has lots of different parts too. A sailboat mast consists of several distinct parts, each serving a specific function. Here are the different parts commonly found on a sailboat mast:

• Masthead: The masthead is the topmost section of the mast. It often includes attachment points for various components such as halyards (lines used to raise and lower the sails), the forestay (the wire or rod that supports the front of the mast), and other rigging elements. The masthead may also house instruments like wind vanes or antennas.
• Spreaders: Spreaders are horizontal bars attached to the mast, typically positioned at specific intervals along its length. They help support the rigging wires and prevent excessive sideways bending of the mast. The position and angle of the spreaders contribute to the proper alignment and tension of the rigging.
• Shrouds: Shrouds are the wires or cables that provide lateral support to the mast. They connect the mast to the sides of the boat, helping to stabilize the mast and distribute the loads generated by the sails. Shrouds are typically tensioned using turnbuckles or other adjustable fittings.
• Backstay: The backstay is a cable or wire that provides support to the rear of the mast. It helps counterbalance the forces exerted by the forestay and the mainsail, preventing the mast from excessively bending forward. Adjustable backstays allow for tuning the mast’s rigidity based on wind conditions and sail trim.
• Halyard Sheaves: Halyard sheaves are small wheels or pulleys located at the masthead or lower down the mast. They guide halyards, which are lines used to raise and lower the sails. Halyard sheaves minimize friction, allowing smooth and efficient hoisting or lowering of the sails.
• Gooseneck: The gooseneck is a fitting that connects the boom to the mast. It allows the boom to pivot or rotate horizontally, enabling control over the angle and position of the mainsail. The gooseneck may include a pin or other locking mechanism to secure the boom to the mast.
• Mast Step: The mast step is the base or fitting where the mast rests and is secured to the deck or hull of the sailboat. It provides stability and distributes the loads from the mast to the boat’s structure.

These are some of the primary parts found on a sailboat mast. The specific configuration and additional components may vary depending on the sailboat’s design, rigging system, and intended use.

I was surprised to learn that sailboat masts are commonly made from several different materials, each offering its own advantages in terms of strength, weight, and flexibility.

The choice of material depends on various factors, including the type and size of the sailboat, desired performance characteristics, and budget.

Here are some of the materials used for sailboat mast construction:

Aluminum is a popular choice for sailboat masts due to its favorable combination of strength, lightweight, and corrosion resistance. Aluminum masts are relatively easy to manufacture, making them cost-effective. They offer good stiffness, enabling efficient power transfer from the sails to the boat.

Carbon Fiber

Carbon fiber has gained significant popularity in sailboat mast construction, especially in high-performance and racing sailboats. You’ll see black carbon fibre masts on fancy sailboats!

Carbon fiber masts are exceptionally lightweight, providing excellent stiffness-to-weight ratios. This allows for enhanced responsiveness, improved performance, and reduced heeling (tilting) of the boat.

Carbon fiber masts can be precisely engineered to optimize flex patterns and provide targeted strength where needed.

Traditional sailboats, particularly those with a classic or vintage design, may have masts made from wood. Wood offers an aesthetically pleasing and traditional look.

Wooden masts can be constructed using solid wood or laminated techniques, which involve layering thin strips of wood for added strength and stability. Wood masts require regular maintenance, including varnishing and sealing to protect against moisture.

In some cases, steel may be used for sailboat masts, especially in larger vessels or those designed for specific purposes, such as offshore cruising or heavy-duty applications.

Steel masts offer robustness and durability, but they are heavier compared to other materials. They require adequate corrosion protection to prevent rusting.

Composite Materials

Sailboat masts can also be constructed using composite materials, such as fiberglass or fiberglass-reinforced plastics. These materials provide a balance between cost, weight, and strength. Fiberglass masts can be an option for recreational sailboats or those on a tighter budget.

It’s worth noting that advancements in materials and manufacturing techniques continually evolve, introducing new possibilities for sailboat mast construction.

The choice of mast material should consider factors such as boat type, intended use, performance requirements, and personal preferences, balanced with considerations of cost and maintenance.

Different Types Of Masts

There are several different types of masts used in sailboat designs, each with its own characteristics and purposes.

We’ve included how the masts are fixed on the boat. This one is an important one when buying a sailboat as you might have a preference over how your mast is attached to the hull or deck.

We’ve also included different rigs, as some boats have just a single mast and other sailboats will have two or more masts. Again, you might have a preference as to which rig set up you prefer so it’s worth knowing the pros and cons of each.

Keel-stepped Mast

A keel-stepped mast is one that extends down through the deck and is secured to the boat’s keel or structural framework. Keel-stepped masts offer stability and strength, as they transfer the loads directly to the boat’s foundation.

They are commonly found in larger sailboats and offshore cruising vessels. We loved knowing our deck was secured to one of the strongest parts of the boat.

It does come with some problems though, like the fact it can leak and start raining in the boat! A decent mast boot will stop this.

Deck-stepped Mast

A deck-stepped mast rests on a step or fitting on the deck, rather than extending down through it. Deck-stepped masts are typically used in smaller sailboats and are more straightforward to install, maintain, and unstep.

They are often lighter and less expensive than keel-stepped masts but may sacrifice some stability and rigidity.

Fractional Rig

A fractional rig features a mast where the forestay is attached below the masthead, typically at a point less than halfway up the mast’s height. This design allows for a larger headsail and a smaller mainsail.

Fractional rigs are popular on modern cruising and racing sailboats as they offer versatility, easy sail control, and improved performance in various wind conditions.

Masthead Rig

In a masthead rig, the forestay attaches at the top of the masthead. This design is commonly found in traditional sailboats. Masthead rigs typically feature larger headsails and smaller mainsails. They are known for their simplicity, easy balance, and suitability for cruising and downwind sailing.

There are various different rig set ups that just have one single mast. We’ll look at a few of the most popular types, but be aware that there are quite a few variations out there these days! It can get a little complicated!

The sloop rig is one of the most popular and widely used single mast rigs. It consists of a single mast with a mainsail and a headsail. The headsail, typically a jib or genoa, is attached to the forestay at the bow of the boat, while the mainsail is attached to the mast and boom.

Sloops offer simplicity, versatility, and ease of handling, making them suitable for a wide range of sailboats, from small day-sailers to larger cruising vessels.

A cutter rig utilizes two jibs : a smaller headsail attached to the forestay and a larger headsail called a staysail attached to an inner stay or a removable stay.

The mainsail is usually smaller in a cutter rig. This rig provides versatility and options for different sail combinations, making it suitable for offshore cruising and handling various wind conditions.

We absolutely loved our cutter rig as it gave so much flexibility, especially in heavy weather. A downside is that tacking is a little harder, as you have to pull the genoa past the stay sail.

Sailboats with two masts tend to be seen on older boats, but they are still popular and quite common, especially with long-distance sailors looking for versatility.

The yawl rig features two masts, with a shorter mizzen mast positioned aft of the main mast and rudder stock. The mizzen mast is usually shorter than the main mast.

Yawls offer versatility, improved balance, and increased maneuverability, making them suitable for offshore cruising and long-distance sailing.

A ketch rig has two masts: a taller main mast located near the boat’s center and a shorter mizzen mast positioned aft of the main mast but forward of the rudder stock. The mizzen mast is typically shorter than the main mast.

Ketch rigs provide additional sail area and options for sail combinations, offering good balance and flexibility for cruising and long-distance sailing. A lot of long-term cruisers love ketch rigs, though they tend to be found on older boats.

The downside is that you’ll have two masts with accompanying rigging to maintain, which isn’t necessarily a small job.

Sailboats with three masts or more are rare. They tend to be seen only on very large, expensive sailing yachts due to the additional expense of maintaining three masts, rigging and additional sails.

They aren’t great for single-handed crews but they do look very impressive and can power bigger vessels.

Schooner Rig

A schooner rig features two or more masts, with the aft mast (known as the mizzen mast) being taller than the forward mast(s).

Schooners are known for their multiple headsails and often have a gaff-rigged or square-rigged configuration on one or both masts. Schooner rigs offer impressive sail area, versatility, and classic aesthetics.

Schooner rigs are much rarer than the rigs mentioned above so it’s unlikely you’ll find one on a cruising vessel.

These are just a few examples of the different types of masts used in sailboat designs. Each rig type has its own advantages and considerations in terms of sail control, performance, balance, and intended use.

The choice of mast and rig depends on factors such as boat size, purpose, sailing conditions, and personal preferences.

We didn’t know the first thing about looking after our mast when we first moved aboard and we made it our mission to find out. When you’re sailing frequently then the last thing you want is to experience a mast coming down mid-passage!

Taking proper care of your sailboat mast is important to ensure its longevity and optimal performance. Here are some tips on how to look after your mast:

• Regular Inspections: Conduct regular visual inspections of your mast to check for any signs of damage, wear, or corrosion. Look for cracks, dents, loose fittings, or any other issues that may compromise the mast’s integrity.
• Cleaning: Keep your mast clean by regularly washing it with fresh water. Remove dirt, salt, and other contaminants that can accelerate corrosion. Use a mild detergent or boat-specific cleaner, and rinse thoroughly.
• Corrosion Prevention: Protect your mast from corrosion by applying a suitable corrosion inhibitor or protective coating. Pay particular attention to areas where fittings, rigging, or other components come into contact with the mast.
• Lubrication: Lubricate moving parts such as sheaves, shackles, and slides with a marine-grade lubricant. This helps prevent friction and ensures smooth operation. Be cautious not to over-lubricate, as excess lubricant can attract dirt and debris.
• Rigging Maintenance: Inspect your rigging regularly for signs of wear, such as broken strands, fraying, or excessive stretching. Replace any worn or damaged rigging promptly to avoid potential mast damage.
• UV Protection: The sun’s UV rays can degrade and weaken the mast over time. Protect your mast from UV damage by applying a UV-resistant coating or using mast covers when the boat is not in use.
• Storage Considerations: If you need to store your boat for an extended period, consider removing the mast and storing it horizontally or in a mast-up position, depending on the boat design. Store the mast in a clean, dry, and well-ventilated area to prevent moisture buildup and potential damage.
• Professional Inspections: Periodically have your mast inspected by a professional rigger or boatyard to assess its condition and identify any potential issues that may require attention. They can provide expert advice on maintenance and repair.

Remember, if you are unsure about any maintenance or repair tasks, it’s always recommended to consult with a professional rigger or boatyard to ensure proper care and safety of your mast.

We learned so much from having our rigging inspected, so we highly recommend you do this if you’re at all unsure.

Conclusion: What Is A Sailboat Mast?

In conclusion, a sailboat mast is a crucial component that plays a vital role in the performance, control, and integrity of a sailboat. It’s a good idea to learn about sailboats before you head out on a sail – unlike us!

The mast serves as a vertical structure that supports the sails, allowing them to capture the power of the wind effectively. The mast enables sailors to control and manipulate the position of the sails, optimizing performance based on wind conditions.

Additionally, the mast contributes to the overall structural integrity of the boat, distributing loads and forces throughout the hull and keel. Various rigging components, such as halyards, shrouds, and spreaders, are attached to the mast, providing support and enabling precise sail control.

By understanding the importance of the mast and properly caring for it through regular inspections, cleaning, corrosion prevention, lubrication, and rigging maintenance, sailors can ensure their mast’s longevity and optimal performance.

A well-maintained sailboat mast contributes to a safe, enjoyable, and successful sailing experience.

Moscow-City: 7 surprising facts about the Russian capital’s business center

1. Guinness World Record in highlining

The record was set in 2019 by a team of seven athletes from Russia, Germany, France and Canada. They did it on September 8, on which the ‘Moscow-City Day’ is celebrated. The cord was stretched at the height of 350 m between the ‘OKO’ (“Eye”) and ‘Neva Towers’ skyscrapers. The distance between them is 245 m. The first of the athletes to cross was Friede Kuhne from Germany. The athletes didn't just walk, but also performed some daredevil tricks. Their record is 103 meters higher than the previous one set in Mexico City in December 2016.

2. Domination of Europe's top-10 highest skyscrapers

7 out of 10 Europe’s highest skyscrapers are located in Moscow-City. Earlier, the  ‘Federation Tower’ complex’s ‘Vostok’ (“East”) skyscraper was the considered the tallest in Europe.

Left to right: the lower of the ‘Neva Towers’ (296 m), Commerzbank Tower in Frankfurt (300 m), Gorod Stolits (“City of Capitals”) Moscow tower (302 m), Eurasia tower (309 m), The Shard’ skyscraper in London (310 m), Mercury City Tower (339 m), Neva Towers (345 m).

However, in 2018, the construction of the 462 meter tall ‘Lakhta Center’ in Saint-Petersburg was completed, pushing ‘Vostok’ (374 m) into 2nd place. The 3rd place is taken by OKO’s southern tower (354 m).

3. The unrealized ‘Rossiya’ tower

If all the building plans of Moscow-City were realized, the ‘Lakhta Center’ in St. Petersburg wouldn't have a chance to be Europe's highest skyscraper. Boris Tkhor, the architect who designed the concept of Moscow-City, had planned for the ‘Rossiya’ tower to be the tallest. In his project, it was a 600 meter tall golden cylindrical skyscraper ending with a spire that was inspired by traditional Russian bell towers. Then, the project was reinvented by famous British architect Sir Norman Foster. He had designed ‘Rossiya’ as a pyramid ending with a spire. The skyscraper itself would have been 612 meters tall, and the height including the spire would have reached 744,5 meters (for comparison, the ‘Burj Khalifa’ in Dubai, UAE, would have been just 83,5 meters taller). Unfortunately, the investors faced a lot of economic problems, due to the 2008 financial crisis, so the ‘Rossiya’ skyscraper was never built. A shopping mall and the ‘Neva Towers’ complex was constructed at its place in 2019.

4. Changed appearance of ‘Federation Tower’

In its first project, the ‘Federation Tower’ was designed to resemble a ship with a mast and two sails. The mast was to be represented by a tall glass spire with passages between the towers. It was planned to make a high-speed lift in it. The top of the spire was going to be turned into an observation deck. But the ship lost its mast in the middle of its construction. Experts at the Moscow-city Museum based in the ‘Imperia’ (“Empire”) tower say, that the construction of the spire was stopped, firstly, due to fire safety reasons and secondly, because it posed a threat to helicopter flights – the flickering glass of the spire could potentially blind the pilots. So, the half-built construction was disassembled. However, an observation deck was opened in the ‘Vostok’ tower.

5. Open windows of ‘Federation Tower’

We all know that the windows of the upper floors in different buildings don’t usually open. Experts say that it’s not actually for people’s safety. Falling from a big height is likely to be fatal in any building. The actual reason is the ventilation system. In a skyscraper, it’s managed with a mechanical system, and the building has its own climate. But in the ‘Zapad’ (“West”) tower of the ‘Federation Tower’ complex, the windows can open. The 62nd and last floor of the tower are taken up by a restaurant called ‘Sixty’. There, the windows are equipped with a special hydraulic system. They open for a short period of time accompanied by classical music, so the guests can take breathtaking photos of Moscow.

6. Broken glass units of ‘Federation Tower’

The guests of the ‘Sixty’ restaurant at the top of the ‘Zapad’ tower can be surprised to see cracked glass window panes. It is particularly strange, if we take into consideration the special type of this glass. It is extremely solid and can’t be broken once installed. For example, during experiments people threw all sorts of heavy items at the windows, but the glass wouldn’t break. The broken glass units of ‘Zapad’ were already damaged during shipment . As each of them is curved in its own way to make the tower’s curvature smooth, making a new set of window panes and bringing them to Russia was deemed too expensive . Moreover, the investors had financial problems (again, due to the 2008 financial crisis), so the ‘Vostok’ tower even stood unfinished for several years. Eventually, the cracked window panes were installed in their place.

7. The highest restaurant in Europe

‘Birds’, another restaurant in Moscow-City, is remarkable for its location. It was opened at the end of 2019 on the 84th floor of the ‘OKO’ complex’s southern tower. Guests at the restaurant can enjoy an amazing panoramic view at a height of 336 meters. On January 28, the experts of ‘Kniga Recordov Rossii’ (“Russian Records Book”) declared ‘Birds’ the highest restaurant in Europe, a step toward an application for a Guinness World Record.

Moscow’s New Supertall Skyscraper Approved for Construction

• Written by Eric Baldwin
• Published on August 29, 2018

Moscow officials have approved a new supertall building that will become the city's tallest skyscraper . Rising 404 meters (1,325 feet) in height as part of the Moscow City commercial district, the tower is designed by Sergey Skuratov Architects. The unnamed structure will be a multifunctional residential complex with 109 floors. The new skyscraper will break Moscow's current tall building record set by Federation Tower at 373-meter-tall (1,226 feet) tall. Construction is scheduled to begin next year.

The new skyscraper joins a host of other superlative buildings in Moscow City, including five of the ten tallest buildings in Europe, all supertall structures.The district's Federation Tower currently holds the title of Europe's tallest completed skyscraper. Soon, it will be surpassed by St. Petersburg's Lakhta Center , which will rise 462 meters when complete in 2019. When complete, Skuratov's skyscraper in Moscow will become Europe's second tallest building.

Designed with two main volumes, the new supertall design includes a 12 story base structure with offices, a shopping center and a range of commercial facilities. Above, residences will rise to the 104th floor. Capped with a helipad, the project includes an observation at 399 meters (1,309 feet) above ground. The project's facade will feature a gradient of white glass between windows that disappears by the 80th floor. As Skuratov explains, "The plan of the building is an isosceles (trapezoid) 30 meters wide, truncated on one side, facing the Moskva River. The sloping edge on the west side of the tower follows the direction of one of the nearby streets. The other edge is vertical and points toward the center of Moscow."

Moscow's supertall is set to open in 2024. Read more about Sergey Skuratov and his work through our recent interview .
