  • Publication number: 20120058693
    Abstract: The present invention is a device affording foot-powered propulsion of a watercraft by an occupant. The device consists of two levers, each with a shaft, serving as a fulcrum. When mounted on a host craft the force arms extend above the deck or floor of the vessel and each has a pedal attached to their end. The resistance arms extend beneath the hull of the craft and each has a folding paddle attached. The levers are linked so that pushing one pedal away from the operator forces the other pedal towards the operator. A back-and-forth pedaling motion moves the folding paddle blades, propelling the vessel. Direction of propulsion can be reversed by rotating the paddles 180 degrees. The invention is intended to be mounted to a watercraft, such as, a kayak that has been specifically designed for or altered to accept the device.

  • Patent number: 7662004
    Abstract: A pair of foils are pivotably coupled to a nacelle. The nacelle is pivotably coupled to a mast extending down from to a frame and below a water surface. A push rod oscillates, causing the nacelle to experience a heaving motion, in turn causing the foils to flap up and down. The push rod is driven by a power plant such as a human rider. Angles of attack for the foils are actively controlled to optimize lift and propulsion forces provided by the foils to cause the water craft to move over the water. A steering fin is also provided for heading control of the water craft. A control system for separate angles of attack for the foil sends appropriate information to servo motors which cause the foils to rotate relative to the nacelle to achieve optimal angles of attack relative to the particular position of the nacelle at any given moment.

  • Publication number: 20040266279
    Abstract: The present invention provides an apparatus for propelling a small boat through a body of water by means of a sculling action. The apparatus may be comprised of a vertical stock attached to a vertical surface of the boat, normally the transom. A wide, flexible fin may project outwardly and rearwardly from the bottom end of the vertical stock. An actuating means, typically a tiller, may extend from the top end of the vertical stock towards the bow of the boat. The pumping action on the actuating means causes the fin to move back and forth in a sculling action so as to propel the boat through the water. The apparatus may be easily folded into a compact package for storage in the boat either for emergency use or for storage of the boat. The fin may be bifurcated into a plurality of panels for more compact and efficient storage. Plates provided to hold the fin in a vertical orientation may have flanges along their upper edges to provide a step for easy reentry of a swimmer into the boat.
