Abstract
Abstract The foldable pontoon boat includes a pair of pontoons extending along and pivotably secured to the opposite side edges of a main deck. The pontoons are foldable between an inner folded position inboard of the main deck and an extended position below and outboard of the main deck. A pair of channel beams are detachably secured by bolts across the bow and stern of the boat. The main deck includes an engine well having a hinged engine cover. A winch, centrally disposed of the boat, winches the pontoons between the folded positions. The deck structure includes a retangular frame member with internal cross brace members sandwiched between a pair of plywood sheets on top and bottom sides of the deck.
