ABSTRACT:
A pedal powered watercraft is disclosed in which a centrally disposed longitudinally extending frame carries a centrally positioned pedal housing having one pedal on each side of said frame with one of a pair of longitudinally extending laterally horizontal boards mounted on each pedal. The frame carries a pair of vertically spaced apart stops constituted by horizontal bars extending outwardly from the frame on each side of the watercraft at the forward end of thereof. The boards extend forwardly of the pedals beyond the bars with these bars being positioned so that the upper bars are below the upper surface of the boards when the pedal carrying the same is at the upper limit of its path of movement, and the lower bars are above the lower surface of the boards when the pedal carrying the same is at the lower limit of its path of movement. This causes the forward end of both boards to point in such a direction that the tilt of both boards moves the craft forwardly when the upper board is depressed.
