A collapsible boat comprises a rigid keel member (1) and a plurality of longitudinal stringers (6) each pivotally connected at each end to respective end of the keel member (1), so as to collapse against the keel member when not required and to fan out therefrom to form the hull of the boat. Vertical members, for example a transom knee (2), a centreboard case (3) and a mast support (4) extend upwardly from the keel member and a rib former (11) is hinged to each side of each of these so as to fold inwardly when the boat is folded for transport and to hinge outwardly to engage the stringers (6) to lock them in their fanned out configuration. The resulting structure is capable of being folded down substantially for transport but is readily opened out into a rigid structure for use. |
