Sun heats dark continents more than reflective oceans. Air moves onshore from high pressure to low. Creating wind: powering weather and stormshurricane-in-a-box-on-water principles producing electricity in a marine vessel, providing Green Technology for Marine Transportation. Captured and recovered heat, offset by loss of heat, creates differential pressure conditions across multiple rotary engines. Night and day, a working fluid moves from high pressure to low; powering alternators, batteries, domestics, and in-hull electric drive trains, in a unique, lightweight exoskeleton dome shell design vessel. Disclosed vessel design advantages include: high energy collection and living space to vessel length ratio; high strength to weight ratio; high carrying capacity, downwind sailing while producing electricity; modular fabrication and shipping; and sustained hull speed in a vessel harvesting energy from the environment. The longer the vessel: the more it carries: the greater the hull speed: the faster it goes.

A variable use pontoon boat configured to operate in both a high speed condition and an improved wake-profile condition is provided. The boat includes a pair of outer pontoons that flare outward in the rearward direction. A rear section of the outer pontoons has a width that is greater than its height. An inclined bottom surface is defined by the outer pontoons. The bottom surface is inclined upward in the rearward direction, and may be inclined laterally upward. The system may include a center pontoon that flares outward in the rearward direction. The center pontoon and the outer pontoons may be spaced apart at a decreased distance at the rear of the boat relative to the front of the boat, such that water is blocked at the rear of the boat and displaced downward. A pair of wake panels may be disposed at the rear of the outer pontoons, and the wake panels may be individually and selectively actuated downward into the water to enhance the wake profile and retracted upward at high speeds.

The present invention discloses a water skateboard apparatus, including a loading component and a number of skateboard bodies that are pushed forward together, where a number of the skateboard bodies are spaced apart, and the loading component is detachably connected to top surfaces of a number of the skateboard bodies. The water skateboard apparatus of the present invention greatly increases the loading space of the water skateboard apparatus by the loading component having a sufficient loading space. The propulsion power of the water skateboard apparatus is greatly improved by providing power through a number of the skateboard bodies. At the same time, the loading component and a number of the skateboard bodies can be installed and disassembled, which is convenient for transportation, maintenance and replacement.

A watercraft has a hull with a central portion which selectively raises from a lower position to a recessed position within a tunnel of the boat hull with a hydraulically controlled means. The hydraulically controlled means is disposed within the hull and adjacent the tunnel. A motor mount is in mechanical communication with the adjustable portion of the boat hull and raises or lowers correspondingly with the adjustable portion of the boat hull.

A boat hull includes a bow section and a flat aft section to allow an air film to be introduced under the boat hull. At least one slot or round hole is arranged proximate a location where the bow section meets the flat aft section. The slot or round hole provides a low-pressure injection point for pumped or drawn-in air and/or exhaust gas, which lubricates an operative surface of the flat aft section.

The systems and associated methods are for autonomously launching and recovering payload objects such as vessels, equipment and people by partially submerging a multi-mode unmanned vehicle in a controlled manner. Mechanical, power, signal and logical system components operate in a coordinated manner to repeatedly and reliably perform unmanned launch and recovery of payloads in a variety of conditions and sea states from a catamaran style hull with multi-mode, high-performance characteristics.

A pontoon boat includes a deck supported by two pontoons extending in a fore-aft direction and water diverters mounted to the pontoons, the water diverters being movable between a neutral position that does not substantially divert water and a deployed position extended laterally from the boat to divert water.

Systems and associated methods for rapid integration and control of payloads carried by a multi-mode unmanned vehicle configured to accommodate a variety of payloads of varying size, shape, and interface and control characteristics. Mechanical, power, signal, and logical interfaces to a variety of payloads operate to enable environmental protection, efficient placement and connection to the vehicle, and control of those payloads in multiple environmental modes as well as operational modes (including in air, on the surface of water surface, and underwater).

An unmanned vehicle may include a vehicle body and a propulsion system carried by the vehicle body. The unmanned vehicle may also include a maneuvering system carried by the vehicle body and a vehicle control system carried by the vehicle body. The vehicle control system may control speed, orientation, or direction of travel of the unmanned vehicle. The unmanned vehicle may also include a mount point carried by the vehicle body. An interchangeable payload deck may be removably connected to a portion of the vehicle body via the at least one mount point. The unmanned vehicle may further include a power supply carried by the vehicle body.
