Abstract: 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.

Abstract: A glow in the dark paddleboard and/or wakeboard is disclosed that is visible in low-light conditions. The paddleboard and/or wakeboard comprises a top surface visible in low-light conditions. Preferably, the paddleboard and/or wakeboard comprises at least one glow in the dark element that is photoluminescent following sufficient exposure to a recharging source. The paddleboard and/or wakeboard are used in surface water sports and allow a user to traverse the surface of a body of water. However, when the user is in or near the water at night, or in other low-light scenarios, the glow in the dark element radiates visible light enabling a companion, or a rescuer to better visualize the user, thereby increasing the likelihood of a successful retrieval or rescue if required, and also prevents accidents as passing boats and other watercraft are more likely to see the individual and not run them over.
