Collapsible boat

摘要

A collapsible boat having a framework comprising forward and aft keel member portions, forward and aft port and starboard gunwale member portions, forward and aft port and starboard stringer member portions, and a plurality of cross-rib members. The keel, gunwale and stringer member portions are joined by interconnecting members into aligned longitudinal members that are also interconnected to the cross-rib members to create forward and aft hull sections. A keel locking and tensioning mechanism is used to join together the forward and aft hull sections at the keel to define a hull framework having elongate keel, gunwale and stringer members that extend longitudinally between a bow and stern and that are spaced and braced by transversely extending cross-rib members. A rocker adjustment system in the gunwale member portions joins the forward and aft gunwale members and permits variation of the elevation of the bow and stern of the framework by adjusting the overall length of the gunwale member portions. The framework is insertable into a flexible water impermeable skin to create a boat with adjustable handling characteristics suitable for use in a wide variety of sailing conditions and environments.
