Roberts Classic 45
The Classic 45 is the long keel version of the R45. With ample room to carry 800lts of water and 600lts of fuel this design is capable of being self sufficient for extended periods. A glance at version A will give you a fair idea where it's name was derived from. The construction plans are well detailed and this design is still worthy of consideration by those after comfort and safety in a fiberglass hull.
The plans come for construction in any of the fibreglass methods- C-Flex, Single Skin or Foam Sandwich.
The various rigs; schooner, ketch or cutter are interchangeable between the short keel version (see Roberts 45 ) and this design.
The study plan package has details of all of the construction techniques and includes materials lists, and accommodation layouts.

Fantasy Boats :
My boat designs are “Fantasy Boats”. I want them to LOOK like REAL boats, GOOD boats, SIMPLE boats, the way boats looked years ago, “Vintage” some might say. They portray boats that might have been, or might one day come to be. I also want models that sail in a realistic manner. No “submarining” on a downwind run, or decks awash and booms dragging in the water while on a beam reach in fair weather. No failures to come about, or unwanted rounding up, out of control, in a moderate breeze. These designs stray from being truly “scale” because they include distortions and compromises which are necessary for the model to sail well. The physical laws of mechanical similitude, the “square-cube thing”, come into play. And that folks, is why my boat designs are the way they are….Cheers, Gary

PDF plans purchased from this website site are delivered via email within 24 hrs or less.
Email delivery is via Dropbox app in the form of PDF files which you can view on your computer. (You don't need to have Dropbox to receive plans). Load the PDF onto a memory stick and take it to a printshop which has a roll fed printer capable of printing 36” (90 cm) wide. Shops which print architectural plans can usually do the job. Ask that the pages be printed “100% - actual size”. Pages with full size patterns or drawings have dimension check lines which can be measured to assure that the printing has been done correctly.
Schooner Irene
Annie is a semi-scale portrayal of a modern cruising “cargo” schooner, designed for RC sailing.
Annie is a Fast Schooner with traditional eye pleasing appearance, good manners, and easy build. We made her longer, leaner, and lighter than my earlier Schooner "Irene” design. More “modern” perhaps, without bowsprit or bumkin, and “racier”, minimizing scale like details, giving her a taller rig with lighter spars, and boom vangs. Annie’s a beauty, She handles like a dream.
How fast is Annie? The fastest boat at the pond? Honestly, it depends on who shows up at the pond that day. She is, after all, a cargo schooner. Annie is a bit faster than “Irene”, a little bit, but only a little! If you are wanting to build a schooner, it could be tough to choose between the sleek “Annie” or schooner “Irene” with her traditional character. Both boats look great, and are a delight to sail.

A traditionally inspired R.C. sailboat for Bear, This stoutly built sailing vessel is stiff enough to hold up to a bear size gale, enabling her to venture far from the protected waters of the local pond, and out into the bay, or even ocean, for long range sailing in open water. Designed by Gary Webb, the renowned full size ocean cruising boat builder, this vessel is worthy of the Bearospace name. Performance is as always, by design. A lot more engineering, calculations, and experience have gone into "IRENE" than most other R.C. Sailboats! Built from inexpensive materials such as doorskin plwood, and epoxy, all but a few parts are available at the local hardware store. This keeps costs at a minimum, and build time in days or weeks, not months or years like some boat models. An optional sail plan with a gaff main sail is included with the “Irene” plan set. Also included are patterns for a skiff and a dory, either of which might serve as a dinghy for “Irene”.

Sailboat Keel Types: Illustrated Guide (Bilge, Fin, Full)
The keel type is one of the most important features of your boat. But the different designs can be confusing, so I've set out to create a very clear guide that will help you understand sailboat keels once and for all.
What are the most common sailboat keel types? The most common sailboat keel types are full-length keels, fin keels, bulb keels, wing keels, bilge keels, and lifting keels. Full keels are popular among cruisers, while fin keels are generally used for racing. Bilge keels and lifting keels are typically used in tidal waters, on small fishing boats for example.
In this article, we'll explore the most common keel types together. I'll use diagrams to really hit home the differences of all these keel types, and we'll discuss what keel types are best for liveaboard, ocean cruising, and lake weekend trips. After reading this article, you'll know what to choose - and why.
Sailboat Keels Explained
On this page:
Overview of sailboat keel types, keel types: fundamentals, modified full keel, centerboard.
If you just want a quick overview, here's a list with the most common keel types and a short description. More detail will follow below.
The most common keel types
- Full keels run from front to aft and are the most stable keel type, making them the most popular cruising keel.
- Fin keels offer the best performance but are less comfortable. This makes them popular for racing. Fin keels are bolted on to the hull and generally run deep and thin.
- Bulb and wing keels are both variants on the fin keel.
- Bulb keels carry additional ballast in the tip, making them more stable.
- Wing keels have two tips at the end of the keel, which reduces crossflow, improving directional stability.
- Bilge keels are double fin or double full kees, which allows the boat to be beached, making them the most popular keel for tidal waters.
- Lifting keels are moveable keels that can be lowered and raised, allowing the boat to enter shallow waters as well.
- Centerboard keels are a pivoting lifting keel, allowing to sail both coastal and inland waters.
- Leeboards are fins on the sides of flat-bottomed hulls boats, making a keel unnecessary.
Properties of each keel type
| Keel type | Comfort | Maneuverability | Speed |
|---|---|---|---|
| Full keel | +++ | -- | -- |
| Modified full keel | +++ | - | - |
| Fin keel | - | ++ | ++ |
| Bilge keel | + | + | - |
| Lifting keel | - | ++ | ++ |
| Leeboards | -- | -- | +++ |
What does a keel do?
What does the keel do? A keel is a vertical blade running down from the hull. It is weighted and acts as a ballast, countering the boat's tendency to heel and preventing it from tipping over. The wetted surface under the waterline reduces slippage to leeward by creating a track, which counters the sideway force of the wind on the sails.
The reason sailboats don't tip over is that the weight of the keel counters the buoyancy of the hull, which means it will pull the boat downward. This downward force reduces heel and prevents the boat from rolling.
A canoe doesn't have a keel. Try stepping into that: it will want to roll.
It counters the horizontal force the wind puts on the sails. Whenever the force on the sails increases, the resistance of the water on the keel increases proportionally.
The heavier the keel, the less heel you'll get.
A keel reduces slippage to leeward. Slippage is simply the amount you fall off course because of the direction of the wind and current. Leeward is the side of the boat behind the wind.
So if you don't have a keel, you will fall off course quite a lot because the wind will push you over the water surface.
You will also heel quite a lot since there is nothing beneath the water surface to counter the force of the wind high up in your sails.
A keel fixes both of these issues and makes sailboats one of the most reliable boats in heavy winds and storms.
You can read on about how keels work here.
Keels can be classified by multiple dimensions. You can look at them from the side or the front. You can also classify them based on properties.
Before I dive into each keel type in-depth and show examples, let's make sure we have the same starting point.
There are essentially two sorts of keels:
Fixed keels
Movable keels.
Fixed keels are keels that are integrated into the hull or bolted on. They can't be moved or lifted.
When looking at fixed keels, you can divide them up further based on the side view. There are three main categories:
Bilge keels
Full keels are more comfortable, provide better stability and protection, but are also slower than fin keels.
Fin keels are less comfortable, provide less stability, are more vulnerable, but they're also a lot faster than full keels.
Bilge keels are double keels: one on each side of the hull. This allows them to be beached, which comes in handy in tidal waters. They are generally a lot slower and less maneuverable compared to fin keels.
Movable keels can be lifted from the water, creating a shoal (shallow) draft, allowing the boat to enter both shallow waters and coastal waters. This makes it a very versatile keel type. There are two main designs:
Lifting keels
Lifting keels can be lowered and raised through a slit in the hull. Examples of lifting keels are the daggerboard and centerboard.
Leeboards are wooden swords attached to the side of the hull and prevent slippage to leeward, but they don't stabilize the boat, nor counter heel by adding ballast.
With fin keels, there are different tip designs available. The most common two tip designs are:
These are both variants of the fin keel. Generally, these keel designs are mentioned in one breath with full keels and fin keels, creating confusion on what kind of keel they are. But it's important to understand that they are a sub-category of fin keels.
Rudder design
As with the tip of the fin, there are different rudder designs that may apply to both fin and full keels. The two most common rudder designs are:
Skeg rudder
Spade rudder.
A skeg is a structural part of the keel in front of the rudder that protects the rudder. The keel encompasses the rudder, preventing any rogue ropes, weeds, or rocks from damaging the rudder.
A spade rudder is an unprotected rudder: it doesn't have any structural protection from the keel design. It is simply attached to the hull. This design is very common.
Alright, we understand the big picture. Let's dive into more detail for each keel type and discuss the pros and cons.
Fixed keel Good for cruising and liveaboards Comfortable
What is a full keel? A full keel runs from front to aft for at least 50% of the hull and is fully integrated into the hull. It has the largest wetted surface of any keel type, and it is also the heaviest. This results in directional stability and reduced heeling, providing the most comfortable ride, but also the slowest.
The wetted surface simply means the amount of water contact area. With such a large wetted surface, it decreases slippage to leeward the most of all keel types, while it counters heeling the most as well.
The full keel is the most comfortable and stable keel type available. However, comfort comes at a price. It delivers the worst performance due to this large wetted area. It is the slowest of the keel types, and it has the worst windward performance.
This makes full keels particularly great for longtime cruisers or liveaboards who prefer comfort over speed, but less ideal for daysailers who need to navigate in and out of slips regularly.
Since it runs for at least 50% of the hull, it doesn't need to run as deep as a fin keel, resulting in a more shoal draft.
Heavier keels result in increased displacement, so a full keel boat will need a larger sail area to compensate for its weight.
For a more detailed discussion on full keel advantages, I recommend reading William's excellent article 5 Surprising Advantages of a Full Keel Sailboat here.
Example sailboats with a full keel:
- Nicholson 22
- Island Packet 380
- Beneteau Oceanis 411 Clipper
- Beneteau First 50
- Jeanneau Sun Shine 38
- Dufour 455 Grand Large
There are a lot of great cruising boats with full keel designs , some of them considered classics.
Full Keel with skeg rudder
Full keels with a skeg rudder design have a protected rudder, thanks to putting a structural part of the keel directly in front of the rudder. This helps with fending off any hazards to the rudder, like floating pieces of rope, rocks, or garbage, and protects it in case of running aground. The skeg design ensures the rudder is nearly impossible to break off.
Fixed keel Good for cruising and liveaboards Faster than a regular full keel
What is a modified full keel? A modified full keel is a full keel with a cutout at the front, reducing the wetted surface slightly, which increases performance without sacrificing too much comfort and stability. After the full keel, it has the best directional stability and the least amount of heel.
The modified full keel is popular among (bluewater) cruisers, thanks to its increased handling and performance. Most modified full keels have a skeg rudder, ensuring it is well-protected.
The slightly reduced weight and wetted surface improve windward performance quite a lot, but it is still one of the most stable keel designs out there.
Example sailboats with a modified full keel:
- Hallberg-Rassy HR 40
- Dufour Arpege 30
- Beneteau Oceanis Clipper 281
- Jeanneau Sun Odyssey 37.2
Fixed keel Good for racing Fast
What is a fin keel? A fin keel is a long, weighted blade attached to the bottom of the hull. It is lighter, faster, and more maneuverable than a full keel, but also more vulnerable. The increased distance between ballast and sails provides a lever, reducing the need for a large wetted surface or additional ballast.
Fin keels are generally bolted onto the hull and run deeper and thinner than a full keel. They are also lighter. This helps increasing performance (a lot), making fin keels a lot faster in all situations.
There are some major disadvantages to fin keels, however. Fin keels are a lot less comfortable than full keels and allow for more heel and a less solid track, so less directional stability. Fin keels are also a lot more vulnerable than full keels. They can break off when running aground, or get damaged.
They are very popular among racers and perform better when maneuvering in tight spots, like getting in and out of slips.
Example sailboats with a fin keel:
- Catalina 30
- Jeanneau Sun Odyssey 36.2
Fin keel with skeg rudder
Fin keels with a skeg rudder use a small structural part in front of the rudder to protect it. This design is mostly integrated into the hull, making it less vulnerable, and a great compromise between speed and safety.
Fin keel with spade rudder
Fin keels with a spade rudder have a completely exposed rudder, and typically a fin that is simply bolted on. The keel isn't integrated into the hull, making it more vulnerable and less comfortable.
Fin keel variant Good for cruising Less crossflow
What is a wing keel? A wing keel is a fin keel with a horizontal foil at the tip, which is wing-shaped and generally weighted. Its shape reduces crossflow, improving directional stability, and its ballast decreases heel, resulting in a more comfortable ride. The addition of a wingtip allows for a shorter fin, reducing draft.
Wing keels are good for cruising since this design improves directional stability compared to a regular fin keel or a bulb keel.
We'll discuss the wing keel's advantages and disadvantages in more detail in this article.
Fin keel variant Good for cruising Stability
What is a bulb keel? A bulb keel is a high-aspect-ratio fin keel with additional ballast at the end, which generally has a bulb or teardrop shape. This ballast improves stability and utilizes the distance between force and counterforce as a lever. This design reduces the need for a deep fin, resulting in a shoal draft.
By placing the weight at the largest possible distance from the force on the sails, you need relatively little extra weight for the same reduction in heel, making bulb keels very effective for cruising.
This design reduces the wetted area while increasing the weight of the keel just slightly, which increases sailing comfort big time.
Example sailboats with a bulb keel:
- Bavaria B/One
- Beneteau First 24
Fixed keel Good for racing Can be beached
What is a bilge keel? A bilge keel is a twin keel which uses double fins, allowing the boat to be beached and rest on its keel upright. Bilge keels have double the wetted surface, which increases comfort and directional stability while decreasing heel. Modern bilge keels often provide decent windward performance, thanks to better design.
The bilge keel does sacrifice speed compared to the fin keel but doesn't necessarily offer worse performance overall. Older designs performed considerably worse than other keels and were especially slow.
Bilge keels have some major advantages over full keels and fin keels. The most important is that the boat can be beached, making it a popular design in tidal waters. Bilge keels are especially common along the British coastline, where fishermen keep their boats in tidal harbors.
Another major advantage is that the boat can be stored resting on its keels, making dry storage and maintenance a lot easier.
Of course, there are many more pros and cons to the bilge keel , which we go into here.
Example sailboats with a bilge keel:
- Dufour Dynamique 62
- Hunter Duette
- Patagonia Patago 39
- Macwester 27
Lifting keel Good for daysailers Versatile
What is a centerboard? A centerboard is a type of retractable keel that rests on a hinge and can be lowered through a slot in the hull. It folds out like a pocket knife and allows you to increase or reduce the draft of the boat. Centerboards are mostly used on small fishing boats.
The centerboard is a very versatile keel type, allowing you to have both a very shoal draft for inland waters, as well as steadying the boat and reducing heel for larger bodies of water, or even oceans.
I've sailed a Cornish Crabber with a centerboard for a week, and while we stayed inland, having the option to increase the keel depth really came in handy when crossing the IJsselmeer (a former sea in The Netherlands).
There's more to the center
Olaf Roethele
https://www.theyachtmarket.com/en/new-boats/cornish-crabbers/adventure-17/218/
My name is Olaf and I am the owner of a Cornish Crabber 17 Adventure boat.
I would like to ask you if you can imagine to install on this boat a Torqeedo 2.0 Pod motor? Therefore i guess a modification of the keel/skeg is necessary ?!
Best regards from Uruguay,
You completely missed the hybrid planing/water-ballast keel of the Macgregor range
Thanks a lot for this explanation

Our first and best selled plan suited for homebuilders.
IDEA 19 originates in 2005 as a modification of Dudley Dix’s TLC 19, a small GRP trailerable sailboat; at the end of the work the only things left from the original project were hull lines, every other aspect of the project was refined, boosted up, and modernized and the plans were converted to a modern wood-plywood and epoxy building system. IDEA19 is a 6m fast paced trailerable sailboat; she can be built by homebuilders in both GRP and wood-plywood & epoxy resin, with strip planking system for hull, and plywood “stitch and glue” system for cockpit, deck and cabin; plans are suited for homebuilders ranging from absolute beginners to intermediate;
hull is a good balance between a quite full bow, sleek amidship lines and a flat and large transom; the boats have achieved a huge amount of miles sailed, both cruising and racing, in all conditions, including several nasty squalls; performance are very sparkly, and the cockpit is surprisingly dry and sound for a small sailboat, with fair and predictable reactions; she has proved to be a tough competitor in club racing (GPH approx. 740 for ORC club rating).
IDEA 19 plans grew in these years as a “family“ of sailboats: you can build her in a long cabin version or in a shorter one, with a really huge cockpit, both in sandwich GRP or in wood & epoxy resin, with retractable or fixed keel, with plywood chined or solid wood round cabin; plans are highly detailed, including all aspects of building and rigging the boat.
The boats launched have sailed thousand miles in these years, in a wide range of environments, from lakes to the open sea, and in a wide range of activities, from family cruising to club racing ; they took beatings in harsh sea conditions up to 30 knots of wind, clocked speed in excess 18 knots planing downind; the boat proved to be a study, forgiving, fun and fast pocket rocket , a very good choice given her overall dimensions.
A lot of building pictures and whole building sequences are on the web, which is something that can mark the difference and speed up the boat building process.
Plans are available both in Italian and English.
Plans are available in imperial units upon request.

Ocean cruising boats and modern hanging keels
Discussion in ' Sailboats ' started by J Smythe , Jul 30, 2019 .
J Smythe Junior Member
Is anyone out there in the design community trying to "modernize" the old school full keel design to garner a couple more knots out of a boat, or is the hanging keel here to stay? As a racer, I can understand going for the hanging or canting keels due to performance, but as an ocean going cruiser, I don't want my keel attachment to be dependent on bolts alone due to so much garbage in the ocean you can run into these days. Whales, shipping containers, abandoned yachts, etc.. Anybody know of anyone with some kind of integrated keel design that's not based on 1980's intel?
jehardiman Senior Member
The selection of a keels has more to do with the intended purpose of the vessel than with fashion. You have a full keel to protect the vessel, you have a bulb ballasted blade to maximize speed or cheat rules. FWIW, there is no ""modernize" the old school full keel design to garner a couple more knots"...keels are integral to the design and selection of the hull.

J Smythe said: ↑ I don't agree with that at all. Most full keel boats weren't designed to "protect the boat", as you claim, but were made that way because "that's the way we always did it.....". Those boats were based on rule of thumb design and scantlings data, not modern naval architecture and hydrodynamics data. Given what we know today, there is no reason that a cruising boat can't have some kind of modernized full keel system integrated into the frame itself that 1.) Reduces the wetted area compared to old design 2.) Reduces drag through modernized keel shape design. There's a couple knots in there just waiting to be had. Click to expand...

Chuck Paine has also developed further the long keel concept, although not perhaps as radically as Bob Perry's Bulletproof 43 above. Both his 30' Mark II version of Annie - ANNIE 2 – A 30′ Offshore Voyager – Chuck Paine Yacht Design LLC https://www.chuckpaine.com/boats/annie-2-30-offshore-voyager/ And the 36' Expannie have hulls with tight turns of the bilge amidships, cutaway keels forward, and a large propeller aperture allowing for the transom hung rudders to be semi-balanced. 36′ Offshore Voyager EXPANNIE – Chuck Paine Yacht Design LLC https://www.chuckpaine.com/boats/36-offshore-voyager-expannie/

Since a cruising boat can afford a little more weight, one option might be to make the fin and it's attachment to the hull extremely strong. However, one argument I've heard is that in rough seas, craft with longer keels and more displacement down low have an easier motion, allowing the crew to function longer or in worse conditions. Also, it was argued that such a boat would be less likely to be rolled over. I don't really know if this is valid.

sailboats. These variations include the "elliptical" keel with shortened root chord and exaggerated midchord lengths. The goal of that design was to reduce the hull-to-keel root chord interference drag. As I'll suggest below, though, there's a better way to minimize drag at the junction of the hull and keel root. The surface of the hull provides a

The most common sailboat keel types are full-length keels, fin keels, bulb keels, wing keels, bilge keels, and lifting keels. Full keels are popular among cruisers, while fin keels are generally used for racing. Bilge keels and lifting keels are typically used in tidal waters, on small fishing boats for example.
