Catamaran-style watercraft with a manually adjustable beam
Abstract:
A catamaran-style watercraft with a manually adjustable beam. The beam expanded or contracted by an operator applying force in a desired direction to a given hull. Movement is afforded by adjustable-length crossbars, which span and connect each of the two hulls, allowing the hulls to slide beneath the underside of an operator-supporting platform deck.
