This application includes an electric powered surfboard equipped with drive units that emerge out onto the surfboard's bottom surface to power it forward. Once a wave is caught the drive units can retract back up into the surfboard's body as the power is shut off by the surfer. Then instantly, flush fitting glide doors close, allowing the surfboard's bottom to return to a planing surface with no protrusions, except for fins 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 personal watercraft includes a floatation member, a thrust assembly, a steering assembly, and a braking assembly. The assemblies may be actuated either mechanically or electrically. The thrust assembly is human powered, solar powered, or electric powered. The thrust, steering, and braking assemblies can be added after-market to an existing stand-up paddle board (SUP), or built into one or a plurality of SUPs during initial manufacturing. When the thrust assembly is human powered, it is leg or arm powered. When the thrust assembly is leg powered, the legs can move backward and forward in a sliding motion, up and down in a stomping fashion, or move in a loop trajectory. When the thrust assembly is arm powered, the arms can move forward/backward together or separately. The thrust assembly includes one or a plurality of paddles or flippers that are positioned to the side or under the SUP.

A surfboard baffle arrangement system may be provided utilizing a watercraft body having a first side surface and a second side surface. The surfboard baffle arrangement system may further utilize an array of baffle structures disposed into the watercraft body and through the first side surface. Each baffle structure within the array of baffle structures may have a baffle retainer and a baffle panel such that the baffle panel and the baffle retainer may be operably coupled to one another. Further, the baffle panel may have one degree of freedom of rotation relative the baffle retainer such that the one degree of freedom of rotation utilizes rotation of the baffle panel between an open configuration and a closed configuration.

Disclosed is a method for controlling a hydrofoil board powered by a motor driven propeller. The motor is controlled by a hand controller configured with user selectable operating pre-sets including a first operating pre-set, wherein the board is accelerated to a first speed which is less than that required for the board to hydrofoil, and a second operating pre-set, wherein the board is accelerated to a second speed sufficient for the board to hydrofoil. Alternatively, the operating pre-sets may limit the motor power. A system for operating a hydrofoil board is also disclosed, which includes a propulsion control unit comprising a propulsion source, and a hand controller configured to receive a first user input and a second user input and to transmit the user inputs to the propulsion control unit.
