ABSTRACT:
A marine propulsion apparatus including a flexible, elongated plate, with a flexible tube attached to each side of the plate, or a flexible plate through which fluid can be passed. In use, the plate is cantilevered to a boat. When water is passed through the tubes at a sufficiently high velocity, the tubes and plate undulate with a downstream propagating wave component, resembling the swimming motions of a slender fish. The result is a forward propulsion of the boat.
