A sailboat is provided with an outboard-projecting elevated attachment or extension wing constructed of large-diameter frame tube elements used in combination for storage, seating, buoyant righting assist, and outboard leveraging of weight or trapezing. Design strength is sufficient to support an aft-extending tube allowing a trapezing sailor to counter-balance forward pitching motion. Design strength also allows outboard extending tube elements to support the weight of the boat in a shallow-water upset. Stresses are distributed to the extent that low-cost, low maintenance plastic can be used for frame tube elements. Broad, large-diameter plastic surfaces are comfortable in contact with the skin, provide secure footing for trapezing, and have reduced tendency to bruise a trapezing sailor in an upset. Internal storage within frame tube elements is supplemented by means for secure outboard attachment of watertight coolers at convenient and conformal locations. Available insulated and un-insulated storage supports use of the catamaran for day-sailing purposes, and a comfortable trap seat reduces sailor fatigue. No drilling or machining of the existing catamaran is required when installed on a Hobie-16 catamaran. Two embodiments are described, supporting slide-in/slide-out and foldable stowage and deployment provisions, respectively. Both embodiments permit convenient trailering of the catamaran. A dual-tiller extension pole assembly operates with the extension wing to relieve tiller extension pole handling difficulties prevalent in small catamarans, and particularly prevalent in small catamarans modified for day-sailing by the inclusion of an aft-mounted motor.
