The disclosed invention is directed to a watercraft which comprises at least one main force member attached to at least one wing; the main force member and/or wing and/or a float attached to the wing comprise sufficient displacement to provide flotation for the craft and its payload. Connected to the main force member is a force transmitting member, to which the engine is connected. The engine may comprise a person or another engine (conventional, electronic, wind, etc.). The engine may comprise a weight which undergoes vertical translation, thereby producing the force transmitted by the force transmitting member to the main force member. |
