Beg-MeilAlbum photosFiche technique

Beg-Meil is a traditional day-boat, gaff sloop rigged, just like many that existed in the old days. It is elegant and seaworthy with its half-deck and varnished wood coamings. A steel pivoting centreboard (40 kg) provides stability and performance. She could be used as a day boat, in the style of old dinghies. You can sail alone, or with a crew of 3 and even 4. She is planked over plywood bulkheads, either with wooden strips or marine plywood lapstrakes. The lapstrake or clinker-built version is easier to build.
Launching and recovering from a trailer is effortless.
Hull shapes are the same as Ilur. Ilur is a reference sail and oars boat, with nearly 1000 plans already sold. The first Beg-Meil, named Pepito, was launched in Carnac in July 2005. She was built by the amateur builder Benoit Brabant using a kit supplied by Icarai. See our photo album. Many others are under construction.

Beg-Meil is now marketed by Icarai which sells also kits for the both wooden version. Please refer to the boatyard Icarai.

Ebihen strip plankedEbihen clinkerAlbum photosFiche technique

Ebihen 15 is a seaworthy, stable boat with good carrying capacity, it is suitable for family sailing, as well as fishing. Despite its length of 4.50 m, it offers a big and pleasant cockpit. She was inspired both by the fishing boats of Northern Brittany, especially Saint Jacut (the Ebihens are the islands in front of that port), and by the boats of Basse-Normandie, which were clinker built.
Many different rigs may be chosen according to your specific needs, from the very simple lug sail to the well canvassed gaff cutter (see drawings). Ebihen 15 is fitted with a heavy metal centerboard that allows excellent stability and good windward ability.
A well for the outboard motor is built aft of cockpit, with the motor handle at helmsman reach. The propeller is just ahead of rudder for good manoeuvrability. A 4 strokes - 4 to 6 hp - motor may be installed.
Ebihen 15 can be built and stored during winter time in a common garage. It is of course trailerable. The first boat of the series was strip-planked (upper picture), with laminated frames and backbone, and almost no plywood. It is a beautiful wooden construction. The clinker version (lower picture) is mainly made of plywood, for planking but also backbone and transverse bulkheads, then much more easy to build by a first time amateur.

A longer version (4.8 m), with same breadth and depth, is also available. She is named Ebihen 16 (see below).
Ebihen 15 plans are also available for a traditional carvel construction. Ask the designer.

Icarai is selling:

Hull/Waterline length: 4.80/4.54 m Breadth:

Sail area (standing lug): 15.5 m²
EU category:  C

Ebihen 16 is a lengthened version of Ebihen 15, with same breadth and depth. This gives more space for the crew and also more sail area. This last aspect is very fruitful for the standing lug version, the sail area being limited by the boat length. Ebihen 16 is also fitted with a water ballast (same principle as Ebihen 18) improving stability and trim. This is very valuable when sailing with a small crew.
Several units are already under construction. The plan package is partly the same as Ebihen 15.
If you have not any length constraint, I strongly recommend to choose Ebihen 16 instead of Ebihen 15.

Lilou construit par CXVLilouAlbum photosFiche technique

Lilou design is based on a fact: day sailing amateurs are mainly supplied with inflatable boats with big outboard motors, motor-boats inspired by the automobile fashion, plastic boats so simplified that you don't know where to turn the mooring line or high tech sail boats with carbon mast and expensive fittings. With Lilou, we intend to supply the demand for a simple but seaworthy boat, with a nice profile inherited from the tradition, but above all adapted to its intended use, offering a large room to its crew (the centerboard case is mostly under the floorboard). We as well intend to provide ease of construction and economy, both for the home builder and the professional, through the use of epoxy resins and NC cut plywood.
Lilou construction use the stitch & tape method. In short, cut the bulkheads and strakes according to the templates, fix them temporarily with metal wires, « weld » the joints with epoxy seams, and cover the whole assembly with epoxy sheathing. This gives a strong and durable hull, which may be trailered behing an ordinary car and handled without special care.
For the rig, we suggest the high peaked gaff sloop, giving excellent performances. Mast is easily stood up and rig quickly fitted. It offers the efficiency of a modern rig and the simplicity of a traditional rig. But a lateen rig or a lug rig are also possible, as they are very practical for fishing, being boomless. A marconi version with an aluminium mast may also be studied upon request.
A well for the outboard motor is built aft of cockpit, with the motor handle at helmsman reach. The propeller is just ahead of rudder for good manoeuvrability. A 4 strokes - 4 to 6 hp - motor may be installed.
Lilou is a trailerable boat that can be launched and recovered easily. She is light enough and requires a simple trailer without any brake system.

Icarai is selling kit as well as ready to sail boat. Very detailed and complete set of plans, as well as full size patterns on polyester film, are available from the designer. The plans are presently not translated into English but I will do it on demand.
Several Lilou are built abroad, UK, Australia, the Nederland...

Ebihen 18Album photosFiche technique

Following the success of Ebihen, a beautiful hull, stable and seaworthy, I have been asked to design the same boat one metre longer, as most owners wish it to be. Then, Ebihen 18 came out of my computer. She is half decked for safety, with a wide space to spend a full day wandering or fishing. It is also possible to spend a night on-board under a tent. Boat and personal equipement are stored in large lockers. Even the long sculling oar is stowed on the floorboards.
To resolve the required heavy displacement (about 1 500 kg loaded) of such a traditional hull and the possibility for it to be trailered behind a car, I have fitted a water ballast tank and a steel centreboard. The tank arrangement is quite simple : a drain plug in the hull and a dinghy type inspection hatch cover just over. After launching, open the plug. When the tank is full, lock the plug and shut the cover. After recovering, just open both to empty. It is also possible to drain into the bilges and to pump the water out before recovering the boat.
The hull is strip planked over a criss-crossed structure made of a plywood backbone, including centreboard case, and plywood transverse bulkheads. The planking is sheathed for better resistance to chafe and to reduce maintenance. The erection of all numerically cut parts is extremely simple, without any measurement and marking, and assure a perfect result for the amateur builder and shortens significantly the labour time for the professional boat-builder. Have a look on the construction 3D sketches.
Ebihen 18 is offered with several rig versions, in particular the gaff cutter and the two masted lug rig named ¤flambart¤ in northern Brittany. Both are superb, efficient, and well suited to this powerful hull. I can also draw other rigs on demand.
A well for an outboard motor, up to 10 hp, is fitted aft. The propeller is just in front of rudder for easy manoeuvering, and the handle is at helmsman reach. The motor is fully hidden under deck. A flush hatch cover allows access for its installation and start up.
The first Ebihen 18 was built by Grand-Largue (near Saint Malo). A second one by Icarai in 2009. A clinker version may be drawn on demand.

Icarai is selling kit as well as ready to sail boat. Very detailed and complete set of plans are available from the designer. Note that it is necessary to buy the plywood kit from Icarai to build the boat. The plans are presently not translated into English but I will do it on demand within a short delivery time.

Béniguet cabineAlbum photosFiche technique

Beniguet is either a pocket cruiser or a day boat. As a cruiser, she offers a cabin with two quarter berths and a third one forward at child size. It is even possible to sleep three adults with a fore berth extension. As a day boat, she welcomes her crew is a two meters long cockpit which offers an exceptional comfort and let you wandering along the coast. A lowered space on both sides of motor well allows to stow a bucket or your fishing equipment.
The cabin gives possibility to take a meal or a cup of tea inside, to find a shelter if raining or some shade on a sunny day. Madam will find a chemical or marine toilet.
The steel centerboard rotates under the cockpit, and does not obstruct the cabin. It gives Beniguet much higher performances than most of the small cruisers inspired by tradition. As usual, I gave a lot of importance to the pleasure of steering a good sail-boat.
The small keel, discontinued aft, makes the boat very easy to launch. It also protects the outboard motor installed in a well which is perfectly within reach of the helmsman, and placed in line of the rudder for easy maneuvers. The purists will be able to dismount the motor under sail, by placing it either in a cockpit locker, or simply place it transversally at the back. Nothing is omitted for a demanding sailor : anchor locker on foredeck, stowage facilities, opening portlight on the coach-roof face etc...
Beniguet is clinker built in plywood-epoxy. A very modern solution which is also in the spirit of a pure classic boat. By limiting the number of varnished pieces or by replacing them with oiled teak, maintenance will be equivalent to that of a polyester hull. The cockpit is water-tight and self draining. The ballast is approximately 170 kg, half of which is placed within the centerboard, and therefore quite low in navigation. All this makes Beniguet a very dependable boat.

Beniguet is built by boat-builder Grand-Largue which also proposes a complete kit including all plywood parts cut on NC machines, most of which not requiring any adjustment.
The very detailed plan is available from te designer both in French and English.

Stir VenAlbum photosFiche technique

Being the winner of the design competition "a boat to go to the islands" organised by Chasse-Marée, in the "revisited tradition" category, Stir-Ven combines classicism and modernity. It gets from classicism the elegance of its clinker built hull, the friendliness of its long and deep cockpit, the aesthetics of a gunter rig with high performances in all weather conditions, the beauty of varnished wood and bronze fittings, the possibility to row when wind is falling (oars are placed under the lateral decks). It gets from the modernity, the plywood epoxy technology, the reduced maintenance requirements, the ease of trailing and launching, the heavy (180 kg) cast iron streamlined centerboard which makes Stir-Ven to sail as a keel boat, both for sailing to windward and safety. Stir-Ven is intended for fast day sailing. It is also suitable for coastal cruising. She has two berths in its small cabin, two others on the cockpit floor under a tent which even allows you to stand up! You can live a few days on board freely, having access to most moorings forbidden to larger cruisers.
For all that, Stir Ven is one of my very prefered design. She is a trailerable boat but not limited to a frustrating one day only sailing.

Today, 40 Stir-Ven have been built, nearly half of them by amateur boat builders. The class is under continuous development. Stir-Ven are now able to race together on occasions of classic boats gatherings on the coasts of France. Their exceptional performances are always remarked.

An Australian builder, Michael Randall, is documenting the work progress with photos you may look at.

Stir-Ven is built by boat-builder Grand-Largue which also proposes a complete kit including all plywood parts cut on NC machines, most of which not requiring any adjustment, and the templates necessary for construction.
The very detailed plan is available from the designer both in French and English.
Full size patterns are available and the corresponding nesting of plywood part has been modified to cope with US panels standard size (8' X 4').

Note : I am interested having other builders of Stir Ven, or representatives, in foreign countries and in particular in North America. This applies also to other designs.

Méaban by Grand-LargueAlbum photosFiche technique

Meaban is a trailerable classic cruiser, with accommodation for 3 or 4. The centerboard is designed in order to pivot under the cockpit sole, avoiding a cumbersome centerboard case in the middle of the cabin. This allows both a large cockpit for day cruising as well as minimum but very practical accommodations with a small galley, many lockers, a toilet between fore berths, a sliding chart table and a foldable dinner table.
A well for the outboard engine is built aft of cockpit, with the motor handle at helmsman reach. The propeller is just ahead of rudder for good manoeuvrability. A 4 strokes - 4 to 6 HP - motor may be installed and is completely hidden under the aft deck.
The cockpit is self-draining for safety.
To be trailerable, the boat needs to be light, keeping a minimum ballast for stability. That why Meaban is built on an  "egg box" structure, with longitudinal and transverse bulkheads made of 10 mm marine grade plywood. The bottom planking is a developed plywood panel. The side planking is cold molded with 4 mm vertical strips of plywood over longitudinal stringers. The planking is lightly sheathed. Alternatively, Meaban may be strip planked.
Meaban is proposed with a gaff sloop rig but a Marconi rig is also possible if preferred.
The first Meaban, made by home builder Thierry Fouchier, was launched in the Basque country in April 2006. The boat performs very well and gives full satisfaction to his owner, both in term of speed and sea-keeping.
Meaban is a modern boat, considering construction techniques and ability to be trailered. But, as for all my designs, I wanted to draw a true classic, beautiful and suited to another way of sailing, away from modern marinas. For instance, the low draught makes Meaban an excellent boat for visiting small drying harbours. Legs are provided to that purpose and a stowage place is arranged under the cockpit.

Méaban is professionally built by Grand-Largue (near Saint Malo). The boatyard is also selling a kit, including a full set of plywood parts cut on NC machine.
Several Meaban are presently under construction in France, Germany, The Nederland, Australia and Czech republic.

Sail area: 32 m²
EU category: C

Koalen 22Fiche technique

In the bloodline of Ebihen 15 and Ebihen 18, Koalen 22 is also inspired by the traditional crabbers of Brittany. The 6.5 m length allows accomodations for 3, still keeping a spacious cockpit. The toilets located under the coachroof, the galley close to companionway, the wide cockpit suited for fishing, will be appreciated for day sailing. The accomodations allow to extend the sailing range, and make a few days cruising along the coast with ability to enter the smallest moorings.

The hull is strip planked over a structure made of crisscrossed plywood bulkheads. As on my other designs, the home builder as well as the professional will benefit from an exceptional ease of construction. The displacement, as well as the 700 kg ballast, gives this small bat an excellent stability and comfortable movement in a seaway. Koalen 22 is also able to sail efficiently to windward without need of the motor.

A 10 hp about diesel engine is suggested. The propeller does not need any notch into rudder in order not to impair steering efficiency.

Koalen 22 is a gaff cutter, a rig perfectly right for this hull. The moderate area of sails, the small bulwark, make the boat easily manoeuvrable even by one man only. The mast is stepped in a tabernacle to allow un-rigging without external aid.

Pen-HirFiche technique

After many years on « sail and oars » boats, and some others on a raid boat (Stir-Ven), I wanted for my own use a keel boat able to sail the same coastal cruising I sailed when I was young. I also wanted to propose a new boat in my catalogue between the centreboarder Méaban and the 8.5 m Toulinguet. A boat big enough to allow a fortnight cruise. But I wanted it very easy to handle, even single-handed, and not requiring a diesel engine, an electrical windlass and all those items now so common but which result in a large and expensive yacht. A small boat gives more pleasure and less trouble. Pen-Hir is the result of 4 years of thinking. My goal was to draw something in the same spirit as the American knockabouts designed by Alden and Crowninshield, very simple, fast and handy sloops. Similar boats were sailing in the Morbihan Gulf (8.5 m SI class), designed by Louis Dyèvre and Gaston Grenier. I was also very fond of Herreshoff designs with their extreme pureness. All those boats were in use during the first third of the 20th century, but I needed a boat suitable for modern use. The cabin had to be larger and the boat wider. Finally Pen-Hir has the looks of traditional yachts of Brest and Carantec areas, with a plumbed stem and a short counter, but keeps the gaff sloop rig with a small bowsprit. I like the gaff sloop with a high peaked yard which is efficient and allows to step the mast in the tabernacle without external aid. A modern bermudian rig is also available on buyer's request.
The size of Pen-Hir, 7.5 m hull length, and its weight allow to trail it. She is fitted with two strong eyebolts allowing to handle the boat with a crane as for Dragon class boats.
The accommodation is similar to Méaban, but with more room, a larger galley and a semi-separated  toilet. The mast is set on a strong but open bulkhead, just at coachroof fore end, thus non obstructing access to fore berth.

The classic lateral plane
All traditional yachts have a classic keel with the rudder attached at the aft. On modern boats, we always try to reduce the wet area and therefore to have a fin keel and a separated rudder. On Pen-Hir, I was very concerned about both performances and the ability to dry out on legs, which makes it possible to avoid calling in modern marinas. I made drag calculations and these show that the number of appendages is a major factor. In other words, a classic keel-rudder is one appendage only, whereas many modern sailing boats have 3 (keel and 2 rudders). A classic keel also gives a more effective lateral resistance, in particular at slow speed, thus being ideal for manoeuvring under sail in confined waters. Finally, the short classic keel, with the tiller at mid-cockpit, combined with a well canvassed rig, appears to be an excellent compromise for a boat requiring easy drying out. In addition, it reduces dramatically the risk of rudder damage. At owner's request, the draught may be modified to cope with local mooring conditions.

The NC cut plywood structure
As many others of my designs, the structure of Pen-Hir is made of criss-crossed plywood bulkheads, including the vertical keel. This allows Icarai boatbuilder in Cherbourg (my own son) to have the boat ready for planking, including most of her accommodation parts, two weeks after receiving the NC cut plywood panels. The bottom planking is made of one single developed plywood panel. The bilge and sides are made of two layers of cold moulded 6 mm plywood.

Sustainable developement
The boatbuilder and I have decided that the first Pen-Hir will be built respecting sustainable development, as much as possible, and we have launched a research and development program with several laboratories. We chose to exclude all tropical woods and in particular okume or mahogany plywood. The boat is made of first class Finnish birch plywood which is extremely resistant and stiff. The only drawback is that birch, as okume, is not a durable wood. Therefore the hull and deck are epoxy sheathed and all edges properly protected. All main timber parts are made of oak, in particular the coachroof coamings. Pine is also used in the accommodations. The mast and spars are made of Douglas fir.
Of course, Pen-Hir may also be built with common marine plywood and red wood as timber.

Electric propulsion
In the same ecological spirit, I have decided to use an electric propulsion. It is based on a new 2 kW Torqeedo ?cruise R?outboard motor giving a thrust equivalent to a 6 hp petrol outboard. A remote throttle control is located in the cockpit at helmsman's hand. The motor is tilted in the aft well, so there is not any speed loss when under sail. Four gel type batteries (100 AH), located under fore berths, allow a range of about 20 nautical miles at 4 knots on a quiet sea. The motor is mainly intended for harbour access and manoeuvering but may also be used to come back to shore if the wind falls down. Batteries can be charged either by the means of a vertical axis windcharger or from harbour electric power.
The aft motor well may also receive a petrol outboard at owner's choice. A small diesel engine, with an offset shaft, may also be installed.

Sail area: 40 m²
EU category: C

MéabanFiche technique

As the 22' version, Koalen 25 is also inspired by the traditional crabbers of Brittany. I have chosen a length just under 7.5 metres, with a generous loaded displacement approaching 3 tonnes. This allows a satisfactory confort for coastal cruising. The counter stern gives a pleasant appearance as well as good sailing ability.

Accommodations include 4 berths (V-berth convertible into double), head (marine type or Porta-Potti) in the fo'c'sle, a well dimensioned galley, a chart table sliding over a quarter berth, a dinner table stowed over the other quarter berth. The cockpit is full breadth, protected by side bulwarks, giving a very large space for the crew.

The hull is cold moulded with plywood over transversal and longitudinal plywood bulkheads. It is protected by a light sheathing.  See pictures of the same technique on Meaban and Toulinguet. As on my other designs, the home builder as well as the professional will benefit from an exceptional ease of construction. A good amount of lateral plane and a heavy ballast keel will give, for such an old looking boat, windward performances that will astonish many sailors. The long keel will also make quiet the most anxious skipper when drying out. The legs themselves are stowed in a cockpit locker..

A 10 hp about diesel engine is suggested. The propeller does not need any notch into rudder in order not to impair steering efficiency.

Koalen 25 is a gaff cutter, a rig perfectly right for this powerful hull. The moderate area of staysail and jib, the simple rig without running backstay, make Koalen 25 easily manoeuvrable by a 2 persons crew. The mast is stepped in a tabernacle to allow un-rigging without external aid.

Album photosToulinguetFiche technique

Toulinguet is a project I have in mind for a long time. Classic wooden yachts, as designed in the past by Cornu in France, Alden in the US, and many others, are becoming very old and more and more difficult to maintain in sailing condition. So I feel necessary to propose designs in the same spirit.
Toulinguet has been designed for both professional and amateur construction.
She is a yacht of the 30's, with the classic hull forms, the old style rigs, the long keel, the discreet coachroof, the large cockpit. She is also a boat of the 60's with the modern wooden construction and practical accommodation well suited to coastal cruising.
Two rigs are proposed, a traditional gaff cutter and a bermudian rig with a large mainsail. Both are well canvassed and are to give good performances.
My aim is to find on Toulinguet the sailing behavior which distinguishes classic yachts : sensible steering, good course keeping, ability to manoeuvre under sail, soft motion at sea... The long keel, with a lead ballast, contribute to that and allows Toulinguet to dry out easily on its legs.
A diesel engine takes place under cockpit, but it is also possible to have an electric propulsion or an outboard motor in a well.
Accomodations for 4, with a double berth in the fo'c'sle and a 1.85 standing headroom.
Construction is made on an « egg box » structure (see photo album), with longitudinal and transverse bulkheads made of marine grade plywood. The bottom planking is a single plywood panel and the bilges and sides are cold molded with plywood. This makes a simple construction based either on a full set of plywood parts cut on NC machine or on full size patterns printed on polyester film sheets. Two unit are presently under construction by home builders.

Toulinguet is sold by Icarai. The boatyard  is also selling the boat as a customable kit.
