Abstract: The current invention offers an instrumental improvement to the prior art of USPTO Rudofsky U.S. Pat. No. 5,643,029 Motorized Surf Boots by providing a connecting Chassis Assembly that provides a rider the ability to lean into or “carve” through a turn (like a downhill snow skier or in-line roller skater does) while keeping each of the boards of the Motorized Surf Boots parallel to each other, at a predetermined distance from each other, and in-line with each other (meaning one board will not shift ahead or lag behind the other). Also included in this chassis invention is a device that provides an automatic and adjustable dampened spring back action, which serves to re-center the Chassis, thus the Surf Boots back into an upright or vertical position, in order to assist the rider in controllably ending the “carving” action and instead continue to move in a straight direction.

Abstract: 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.

Abstract: A fleet of autonomous sailing vessels that are equipped with monitoring and communication equipment for reporting environmental and other conditions. For optimal stability, the autonomous sailing vessels are multi-hulled vessels (catamarans) with self-righting capabilities. Each sailing vessel sends and receives information via one or more satellite links, using solar power to power the communications equipment as well as the monitoring equipment. Each sailing vessel includes an auto-sailtrim system to maintain a desired attack angle with the wind, and electric propulsion for use as required to maintain a desired heading. A modular design is used to support mission-specific payloads.

Abstract: A seagoing vessel having a length of between 45 and 175 meters and designed to operate at speeds of between 25 and 70 knots, the vessel comprising a single main hull with stabilising amahs positioned on either side, wherein the hydrostatic value of GM determined in the transverse plane lies between 0.5 and 5 meters, the vessel being shaped above the designed waterline such that the righting lever (GZ) curve as the vessel heels meets the following requirements: the area (b) bounded by the GZ curve plotted on the heeling axis between the angle of flooding and the heeling lever associated with a specific gust of wind is greater in value than the area (a) bounded by the GZ curve plotted on the heeling axis between the heeling lever associated with the specific gust of wind and an angle associated with the amount of roll of the vessel to windward under the action of the waves.
