This new art offers an improvement to conventional surfboards as well as any previous motorized jet surfboards. This application includes an electric powered surfboard equipped with high volume jet drive units that power it forward and significantly improve a surfer's wave fielding and catching ability. Once a wave is caught the drive unit can be shut off by the surfer. Then instantly, two flush fitting glide doors close the jet tube intake openings allowing the surfboard's bottom to return to a planning surface with no protrusions, except for fins, and no water filled jet tubes left open to detract from the surfboard's critical gliding ability when surfing waves. Also, there's a crowned deck shape that allows thin rail sensitivity for turning performance and a motor battery arrangement that provides mass centralization of weight. All this, combined with several wireless control means define this new fine handling motorized surfboard.
A surfboard having a body with top and bottom surfaces, wherein the body of the surfboard is configured to support a surfer lying in a prone position or standing on the top surface while moving forward, the surfboard defining a longitudinal axis and having a nose at the forward part of the surfboard and a tail at the aft part, also having a single stringer, and with foam and fiberglass construction and with multiple fins, the surfboard is configured to be electric powered and is equipped with at least one brushless motor that is operatively connected to at least one jet drive unit that is contained within the body of the surfboard and is configured to take in water through an intake opening of a jet tube in the bottom of the surfboard and exit through a nozzle at the tail to power the surfboard forward, and allowing a surfer to field and catch waves without paddling, wherein as soon as the wave is moving the surfboard forward, the surfer can close an intake door by pushing a button that enacts a power off sequence provided in a radio control circuit board contained within the body of the surfboard, and configured to receive throttle commands as well as servo and or linear actuator commands to close the intake door, wherein said intake door is configured to close the jet tube intake opening with a substantially seamless fit across the surfboard's bottom surface, thus allowing the surfboard's bottom to form a planing surface without the intake opening causing drag and disrupting water flow, therefore enabling the surfboard to glide freely and the surfer to ride on the wave's power only, the intake opening provides a volume of water to enter the jet tube that leads into an impeller that forces the water out of the jet nozzle allowing a compressed, formed, high pressure stream of water out the tail of the surfboard,
