Abstract: A kit for converting a conventional surfboard into a motorized one, to assist a surfer in paddling away from shore, includes a small motor attachable to the surfboard and a control remote. The electric motor is built directly into a rudder or fin, attachable to the surfboard without any structural modification to the board. The remote control is wireless and worn on the surfer's hand or wrist. With a motorized surfboard propelling the surfer forward at a low rate of speed, it is unnecessary for the surfer to exert considerable energy paddling out to catch another wave.
