An aftermarket adaptor apparatus for a float-board is disclosed. My invention permits a user to adapt a conventional buoyant water float-board (typically a stand-up paddleboard, surf board, or other floatable device), to effectively convert it into a foot-propelled exercise board. The adapted float-board allows a user to travel across, over, and through water by the action and means of the user's feet treading and ambulating upon a treadmill integral to said adaptor apparatus (after its attachment onto said float-board). In practice, the treadmill is affixed onto and over the upper surface of the float-board at the time of the adapter being attached. Accordingly, the affixed adaptor upgrades a simple float-board for treadmill propulsion through the water. The adapted float-board permits a user to self-propel over, across, and through a body of water. This is accomplished by (1) the user attaching said adapter securely onto said float-board, (2) the user positioning the adaptor in place by strapping down the adaptor, (3) the user placing the adapted float-board into the water, and then while afloat and getting underway, (4) the user balancing and standing on top of and treading upon the adaptor's integral foot-actuated treadmill which is suspended over the buoyant coupled assembly comprising the original float-board with its attached propulsion adaptor.

A drive module for submersible autonomous vehicles is disclosed. The drive module includes a propulsion element configured to engage and rotate against a surface, a motor configured to drive the propulsion element, and a controller configured to cause the motor to drive the propulsion element. The drive module also includes a housing configured to be removably, releasably coupled to the exterior of a submersible autonomous vehicle. The motor and the controller are disposed within the housing.

A vehicle includes a propulsion system using one or more impellers as opposed to propellers. The impellers impart circumferential and radial velocity components to the working fluid, which may be air or water. The air is deflected by counter-vortex chambers in a shroud to convert the circumferential and radial velocity to an axial velocity aligned with the axis of rotation of the impeller.

A boat comprises a deck supported by one or more deck floats, and a paddle wheel cockpit comprising a seat proximal to a pedal-driven paddle wheel adapted to engage water and propel the boat; wherein the deck and the paddle wheel cockpit are joined by at least one cockpit hinge that allows the paddle wheel cockpit to fold over the deck, in some embodiments.

A high speed ship configuration for achieving a plane state efficiently, with threshold power available in fully loaded cargo ship. The system may include a boost phase assist structure to assist in the achievement of a plane state. The boost assist may be external or internal to the ship. The boost assist may provide power and/or lift assist. One embodiment may include a launch rail. In one embodiment, the configuration includes a retractable lateral wing structure disposed toward the stern of the vessel and containing auxiliary power providing thrust for the vessel. The wing structure is deployed during an initial boost phase acceleration and may be stowed in the vessel once the vessel achieves full plane operation. In one embodiment, the boost power structure may include propeller drive, paddle drive, or waterjet drive. The boost power structure may provide buoyancy and/or hydrodynamic trim to assist in achieving plane state operation.

A lightweight amphibious vehicle system enables a user to traverse the land or water in the same craft. The wheels have paddles attached on the sides and are powered by a transmission that multiplies the force of a user to enable the system to travel without great effort. The transmission is driven by pedal power input by the user.
