A narrow beam rotomolded foam filled catamaran that incorporates regular points of attachment through the deck and a tubular frame that is highly customizable with modular accessories making it ideal for maneuverability, stability, durability, transportation, storage, and customization.

A self-propelled waterborne wave riding system includes a vessel having at least one motor and control system for navigating and propelling the vessel along a body of water. A rider section is located along the top of the vessel and includes a lower platform at the front of the vessel, an upper platform at the back of the vessel, and an elongated angled ride surface that extends between the upper and lower platforms. A pump system is provided along the vessel and includes an impeller assembly that is mechanically coupled to an inboard motor and a water pipe. Water received by the impeller is directed through the water pipe to a horizontally oriented nozzle in the lower platform which pushes the water over the ride surface. Openings in the upper platform return the used water into the body of water.

Embodiments described herein relate generally to a sailing vessel that can substantially obviate the heeling problem experienced by classical sailboats. During navigation, the sailing vessel is driven forward by an aerodynamic force exerted by wind on the sail, and balanced by a hydrodynamic force exerted by water on a float on the stern of the sailing vessel, the aerodynamic force and the hydrodynamic force being parallel or substantially parallel to a longitudinal axis of the sailing vessel.

A trimaran which includes a self-righting structure positioned near the stern that substantially raises the center of buoyancy. The trimarans two peripheral hulls are shorter than the main hull and positioned near the one end to create an unstable inverted environment wherein when inverted the vessel rests primarily on the self-righting structure and an end of the main hull, substantially raising the center of gravity and creating an unstable configuration. This causes a pitch or roll about the vessel's longitudinal axis, which continues until the vessel has returned to its more stable upright position resting on three hulls.

A pontoon boat includes port and starboard pontoons and cross members connecting the pontoons. A shock absorber may be installed at each point of connection of the pontoons to the cross members. A cross member may be embodied as a double-webbed beam having first and second parallel flanges and first and second webs disposed between and connected to the flanges. Each pontoon may include a two-stage lifting strake having a first surface and a second surface inclined from the first surface.

A narrow beam rotomolded foam filled catamaran that incorporates regular points of attachment through the deck and a tubular frame that is highly customizable with modular accessories making it ideal for maneuverability, stability, durability, transportation, storage, and customization.

An ultra-fast trimaran deep water and littoral naval ship suited to combat, search and rescue, and/or deployment operations has a plurality of semi-planing hulls connected to the underside of a deck in a trimaran configuration. Further, a plurality of propulsion stages including a cruise propulsion stage, a wind assisted propulsion stage, and a vectored direct thrust propulsion stage may be independently operated alone or in conjunction to propel the ship at various speeds suited to different situations.

A pontoon boat including a thruster system is disclosed. The pontoon boat executes various operations relating to a speed and heading of the pontoon boat.

A pontoon boat is provided that includes a deck and a plurality of pontoons running longitudinally beneath the deck and providing buoyancy to the pontoon boat. The plurality of pontoons include a multi-chine configuration that increases the stability of the pontoon boat and provides handling characteristics similar to that of a hulled boat. The plurality of pontoons may include two outer pontoons and a third pontoon positioned laterally intermediate the outer pontoons. The third pontoon may include a plurality of chines, and each of the outer pontoons may include at least one chine. At least a portion of each of the at least one chines of the outer pontoons may be positioned vertically below the plurality of chines of the third pontoon. The chines on the third pontoon may extend longitudinally further than each of the at least one chines of the outer pontoons.

An aquatic vessel, illustratively a pontoon boat including a thruster system is disclosed. The aquatic vessel executes a process to automatically position the aquatic vessel relative to a target location such as a mooring implement. Exemplary mooring implements include a dock, a slip, or a lift.
