ABSTRACT:
A motor driven surfboard is provided including a surfboard housing having a top face and a bottom portion integrally coupled to the top face. The bottom portion includes a starboard extent and a port extent. Further provided is a vertical rear face formed between the top face and bottom portion for defining an interior space. The surfboard housing further includes a fin coupled to the bottom portion between the starboard and port extent thereof. Next provided is a pair of water jet passageways having a pair of conduits including a starboard conduit and a port conduit. Each conduit includes a circular entry formed in a center of the respective extent of the bottom portion of the surfboard housing and in communication with a respective circular exit formed in the rear face of the surfboard housing. Also included is a control unit for allowing the manual generation of an actuation signal. Finally, a motor driven propeller is situated within the surfboard housing between the entries and exits of both of the conduits of the passageways. The motor driven propeller is connected to the control unit and adapted to force water through the entries of the conduits and out the exits thereof upon the receipt of the actuation signal thus propelling the surfboard housing forward.
