ABSTRACT:
A composite skin tar a collapsible canoe. The skin covers a frame which includes a pair of gunwales, ribs, and stringers. The skin has a pair of polymer-coated gunwale sleeves which slidably engage the gunwales, a pair of polymer-coated side panels, each attached to one of the gunwale sleeves, and a polymer-coated bottom panel attached to the side panels. In one embodiment of the skin, the side panels are attached to the bottom panel with a heat sealed seam. One aspect of the invention is the gunwale sleeves, each of which has a fabric layer, providing a surface with reduced friction to allow the gunwales to be inserted or removed without binding. Another aspect of the invention is the bottom panel, which is constructed from a bottom fabric substrate having an uncoated inner surface, to which is attached a foam pad. Preferably, longitudinal rub strips of a polymer film are bonded to the coated outer surface of the bottom panel. Another aspect of the invention is a pair of side flotation compartments, each having a flotation chamber sleeve which is configured to slidably accept a plurality of individually removable flotation chambers. The flotation chambers are of a polymer film, allowing them to readily be repaired in the field.
