  • Collapsible boat
    Patent number: 5488922
    Abstract: A collapsible boat having a contoured hull shape is disclosed in which the individual component surfaces of the hull may be folded both longitudinally and transversely via disengageable clamping mechanisms that maintain the boat water-tight when it is fully assembled. The lateral edges of the individual hull components, made preferably of aluminum, are profiled so they may be pivoted around a common axis into a relative position where they press together against one another to form a water-tight, longitudinally stable hull.
