ABSTRACT:
A buoyant craft, such as a boat or raft, propelled by a water jet thrust of high efficiency. Such thrust is provided by a wedge shaped chamber, such as one including a substantially flat plate pivotally mounted forwardly and on the underside of the craft and having two vertical sides. Pedals are provided on an extension of the flat plate. A modification involves the use of two separate wedge shaped jet thrust chambers with a common central wall to permit better steering. Still another modification involves the use of a wedge shaped chamber made of rubber or other flexible elastomer which is squeezed by pivotal movement of the pedal-operated flat plate to effect jet propulsion.
