B63H 16/18
US Classification:
440 13, 440 21
Abstract:
A human propelled watercraft having a pair of flexible fins extending into the water each adapted to oscillate through an arcurate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft. Pedals are provided for applying input force whereby as input force is applied, the flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along the arcurate path. Each of the fins preferably have a generally squared off top and an outer area of harder rubber than the inner area. Preferably, each of the fins is provided with adjustable tensioning at the trailing edge.

James T. Czarnowski - Encinitas CA, US
International Classification:
B63H 1/30
US Classification:
440 13
Abstract:
A watercraft having propulsion means extending below the water line comprising a pair of flexible fins each adapted to oscillate through an arcuate path in a generally transverse direction with respect to the central longitudinal dimension of said watercraft, and means operatively associated with said propulsion means for applying input force to said propulsion means whereby as input force is applied said flexible fins can twist to form an angle of attack for providing forward thrust with respect to the longitudinal dimension of the watercraft while moving in both directions along said arcuate path;the improvement wherein each of the fins preferably have a generally squared off top and an outer area of harder rubber than the inner area. Preferably, each of the fins is provided with means at the trailing edge to provide adjustable tensioning of the trailing edge, preferably by threaded means at the clew of the trailing edge.

International Classification:
B63B 1/24
B63H 9/04
B63H 9/04
US Classification:
114 3924
Abstract:
A watercraft having a hull, a mast with sail, an aft rudder and a hydrofoil projecting below the bottom of the hull. The hydrofoil is pivotly connected to the hull enabling the hydrofoil to pitch on a pivot axis which is essentially perpendicular to the longitudinal axis of the hull. The hydrofoils have a vertical part which produces lateral forces to accelerate the boat in turns and resist lateral forces from the sail, and a vertical portion which curves into the horizontal portion which produces vertical lift. The angle of incidence of the hydrofoil is controlled by a sensor arm carrying a trailing sensor.
