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.
