A computing apparatus that is integrated within a flotation module, the system obtaining the energy required to power its computing operations from waves that travel across the surface of a body of water on which the flotation module sets. Additionally, the self-powered computing apparatus employs novel designs to utilize its close proximity to the body of water and/or to strong ocean winds to significantly lower the cost and complexity of cooling their computing circuits.

A motorized, steerable, electrically-operated personal watercraft that includes a hull with a bow, stern, top deck surface, underside surface, and a support and steering console. The deck is configured to allow a user to lie prone on the deck with the user's chest located on or proximate the console. There are left and right steering control devices located at the left and right of the console, respectively. The steering control devices are configured to be manipulated by the left and right hands of the user. Motive power and steering are both provided through an electrically-powered water jet, which may be but need not be located at the stern. The water jet is mounted to a fixture that is configured such that the outlet nozzle of the jet can be turned left and right, in order to steer the craft to the left and right. Jet nozzle steering is accomplished by manipulation of the left and right steering controls. User-operable kill switches also located at the left and right of the console must be operated in order to operate the jet.

A small marine vessel includes a vessel body, a propulsion device, a propulsion device housing provided in a rear portion of the vessel body and that houses the propulsion device, a first cover that substantially covers and seals the propulsion device housing, and a second cover disposed above the first cover and that covers the first cover and an opening of the propulsion device housing.

The present invention includes an underwater vehicle power unit and method of operating the same comprising: a fuel and waste stack comprising one or more reactant or fuel storage bladders and one or more waste storage bladders; a heater; a reactor that generates hydrogen and waste; a hydrogen and waste separator; a back-pressure regulator; a hydrogen and liquid separator; a fuel cell; and a controller that controls the temperature of the heater, the flow of fuel into the reactor, the flow of hydrogen into the fuel cell, the flow of water that dilutes the fuel, the flow of waste from the reactor and/or the fuel cell into the one or more waste storage bladders.

A small watercraft includes an input, a second storage, and a controller. The input receives an operation to switch the small watercraft into one of a plurality of control states, and includes a first storage that stores first control information indicating the one of the plurality of control states associated with the operation received by the input. The second storage stores second control information indicating one of the plurality of control states. The controller is able to write to one of the first and second storages. The input is supplied with electric power by supplying the controller with the electric power. When the one of the plurality of control states indicated by the first control information is different from the one of the plurality of control states indicated by the second control information, the controller causes one of the first control information and the second control information stored in the one of the first and second storages to match the other of the first control information and the second control information stored in the other of the first and second storages.

A jet pump includes a propulsion system including an impeller coupled to a rotatable shaft configured to receive torque from an engine and an exhaust system including an exhaust flow path configured to direct exhaust from the engine to an exterior of the watercraft, wherein the exhaust system is integrated with the propulsion system. In another embodiment, a jet pump includes a propulsion system including a water intake configured to take in water from a body of water, the water intake including an intake grate and an intake base, and an exhaust system including an exhaust flow path configured to direct exhaust from the engine to an exterior of the watercraft, wherein the intake base of the water intake is configured to be coupled to an exterior surface of a hull of the watercraft.
