초록 ▼

An improvement to a conventional surfboard includes an impeller and an electric motor contained primarily within the body of the surfboard, whereby performance of the surfboard is substantially unaffected by the presence of the impeller and the electric motor. The electric motor is operatively connected to the impeller for providing a forward thrust of the surfboard. The improvement to the conventional surfboard also includes a throttle for selective control of the electric motor for operating the impeller to provide a forward thrust of the surfboard, the throttle being configured for use by a surfer lying in a prone position on the smooth top surface of the body of the surfboard. An extent of the surfer's energy that otherwise would be expended during paddling can be preserved for riding waves by using the impeller to provide the forward thrust during paddling.

1. A motorized surfboard comprising: a body configured to float in water, the body having a top surface and a bottom surface, the top and bottom surface having a forward portion and a rear portion, the forward portion terminating in a frontal nose and the rear portion terminating in a rear tail, the body having no substantially protruding parts from the bottom surface other than fins extending from the rear portion of the bottom surface;at least one tube extending through the body, the at least one tube connecting at least one entrance hole located on the bottom surface to at least one exit hole located on at least a portion of the rear tail;at least one impellor contained within the tube;at least one electric motor contained within the body of the personal watercraft, the electric motor being operatively coupled to the impeller for providing a forward thrust to the personal watercraft by drawing water in through the at least one entrance hole and out of the at least one exit hole;one or more batteries contained within the body of the personal watercraft, the one or more batteries configured to provide power to the electric motor; anda circuit board contained within the body, the circuit board configured to receive wireless commands from a surfer on the body for controlling the electric motor. 2. The motorized surfboard of claim 1, further comprising at least one dry box disposed within the body. 3. The motorized surfboard of claim 2, wherein the one or more batteries are disposed within the at least one dry box. 4. The motorized surfboard of claim 2, wherein the circuit board is disposed within the at least one dry box. 5. The motorized surfboard of claim 1, wherein the entrance hole is located on the rear portion of the bottom surface. 6. The motorized surfboard of claim 1, wherein the at least one electric motor is rated at greater than 150 watts. 7. The motorized surfboard of claim 1, wherein the at least one electric motor is rated between 150 watts and 450 watts. 8. The motorized surfboard of claim 1, wherein a diameter of the impeller is less than a thickness of the body. 9. The motorized surfboard of claim 1, further comprising a recharge port positioned to allow for recharging of the one or more batteries without direct access to the cavity. 10. The motorized surfboard of claim 1, wherein the impeller and the electric motor both are contained within the body such that neither protrudes beyond either the top and bottom surfaces of the body. 11. The motorized surfboard of claim 1, wherein the body has a maximum thickness between the top surface and the bottom surface of approximately three inches.
