Abstract
A self-propelled boat (10) to be used by a boater to maneuver himself along the surface of a body of water, especially in shallow water where the use of a motorized boat or a deep bottom boat is impossible or otherwise impractical. The self-propelled boat (10) includes a body (12) to carry the boater and provide buoyancy. A seat (14) is provided on which the boater may be seated, the seat (14) being provided with a position adjuster (88) for fixing the seat (14) at selected positions along the longitudinal axis of the boat (10). A propulsion system (16) is provided such that the boat (10) may be maneuvered along the surface of the water. The propulsion system (16) includes a pair of foot mounts (146, 148) for engaging the feet of the boater to oscillate selected cords (132L, 132R, 138), the cords (132L. 132R, 138) being connected such as to form a loop. Bow and stern pulleys (98, 106) are provided for holding the cord (132) in place. As the cord (132) is oscillated, at least the stern pulley (106) is simultaneously oscillated. The stern pulley (106) then serves to oscillate a shaft (108) to which a flexible fin (154) is attached. Thus, as the fin (154) is oscillated, the boat (10) is propelled in reaction in a similar manner as a fish is propelled.
