Abstract
A watercraft comprises a motor, an inertial mass, and a fin. The motor oscillates the inertial mass about an axis, producing a torque reaction on and oscillation of the motor. Oscillation of the motor is communicated to the fin, producing thrust.
Claims20
A watercraft comprising a fin, a motor mounted to a hull and an inertial mass, wherein the motor cyclically counter-accelerates the inertial mass and is subject to a torque reaction caused thereby, wherein the torque reaction on the motor from cyclic counter-acceleration of the inertial mass is communicated to the fin via the hull, resulting in a translation of the fin through a surrounding thrust fluid, wherein the translation of the fin though the surrounding thrust fluid produces thrust.
