Abstract
A device for insertion in watercraft including propulsion means comprising a pair of flappers which oscillate through an arcuate path in a transverse direction with respect to the central longitudinal dimension of the watercraft. As input force is applied, the flappers twist to form an angle of attack for providing forward thrust. The means for applying propulsive force includes a pair of pedals, and further includes pedal cranks operatively associated with the propulsion means, the fore ends of the pedals being pivotally attached to a fixed point.
