ABSTRACT:
A boat capable of being assembled, disassembled and transported by one individual and without any tools or special equipment. The boat comprises a superstructure which is substantially of lightweight buoyant material such as foam board, and which includes a pair of ski-like hulls, a longitudinal member removably attached to each hull, and a pair of transverse members removably interconnecting the hulls in spaced relation. A cockpit area is provided between the hulls and transverse members. The superstructure is preferably composed of only three components employed in pairs; the hull members, the longitudinal members, and the transverse members. Each of these components are preferably die cut from the same material, and each component of the superstructure has joint elements integrally formed therewith for interconnecting the components. When used as a sailing craft, a mast is removably attachable to the superstructure and to which a sail assembly is rigged. A rudder is removably attached to the aft end of each hull and a daggerboard can be removably installed in each hull. The boat can also be used with paddles or with an outboard motor.
