Home 40ft tacking outrigger sketch Please find sketches of a low cost, simple 40ft outrigger canoe. The idea is to create a seaworthy, simple, spartan vessel that could comfortably undertake blue water cruises, yet still retain some very useful features such as shoal draught, and low capital and ongoing costs. I would think that a vessel like this would be best be built using epoxy strip plank construction with a thin veneer over the strip planking. Such a method would be more labour intensive than say hard chine plywood construction, however is built in a poorer country and utilising the lower labour costs, the total cost of the vessel would be quite modest. It should be noted that in many ways the hull shape is inspired by Wharram Taoma Mana ethnic series double canoe. The twin crab claw sail rig would not work on this vessel because of lack of locations to place diagonal stays. Aft leading stays are not compatiable with the crab claw rig. Overall Concept The concept is to provide a large hull for the accommodation and facilities within. This gives the vessel large intrinsic reserves in terms of seakeeping potential and load carrying capacity. The idea is to underload the hull as opposed to overload the hull. Costs are lowered by using wood as opposed to expensive stainless steel and carbon fiber fittings. Look of the vessel The saying is that if it looks right, it is right. For me this boat looks very good to my eye. It is true this is a subjective thing, however i think it is better that in my view it looks right as opposed to not looking right Sail area I have compared the boat to the similar length Gaia 1 tacking outrigger by Ingio ****. Although length is similar this vessel has longer overhangs and a smaller cabin, and it is anticipated that weight would be less, thus sail area is only 85% of Gaia 1 tacking outrigger. Some features of this vessel There are two single berths There is 6ft 2 inches standing headroom Only one large hull needs to be built There are two relatively modest mainsails that are easily handled by the solo sailer Crossbeams are wooden box beams, light, simple and strong Minimal electrics, nav lights, interior lights, cooling fan There is a large flat deck to walk which is good for exercise Center of gravity is low Draught is only two feet, which is good for beaching The large overhangs reduce performance to a degree, however these provide excellent protection from a following sea The center of gravity is low which is good for safety Stay angles are low, thus reducing mast compression loads A tender can be placed on the non outrigger side, between the safety ama and main hull The lack of a skeg and fixed rudder permits beaching on remote beaches (with assistance of course) Please note, this vessel is best thought of as a 30ft multihull with overhangs, as opposed to a 40ft multihull The back stay (as opposed to trianglar arranged stays), do not interfere with the mainsail moving abeam and thus spilling wind Methods of reducing vessel capital cost Spartan living conditions Elimination of complex centerboard/daggerboard Eliminating luxuries such as separate head, refrigerator, shower, electric winches Use of blocks instead of winches to handle sails Wooden masts instead of aluminium masts Elimination of internal engine Elimination of bridgedeck and the associated weight, windage and cost Only a small part of one main hull has standing headroom, thus minimising windage Home
