Abstract: The patent discloses a multihull watercraft with a unique hull configuration providing numerous benefits. Passenger cabins are enclosed within a separate upper hull, which allows the accommodation space and the float hulls to be independently optimized. The new configuration also provides reduced windage, and creates additional deck space for easier boarding, recreational use, and safer access to shore craft.

Abstract: The patent discloses a multihull watercraft with a unique hull configuration providing numerous benefits. By relocating the passenger cabins from the float hulls to the upper hull, the accommodation space and the float hulls may be independently optimized. The new configuration also provides reduced windage, and creates additional deck space for easier boarding, recreational use, and safer access to shore craft. A new sailing rig is also disclosed that is easier to operate and maintain than the conventional Bermuda rig. The entire rig can be rotated with a single winch or control wheel to achieve the optimum angle of attack into the wind.

Abstract: A multihull hydrofoil watercraft incorporates a stabilization system wherein the buoyancy of the hulls is used as a sensing and control mechanism for the hydrofoils. The use of hull buoyancy to adjust the hydrofoil lift provides for automatic control of altitude, pitch and roll, and allows the craft to accommodate varying weather and sea conditions while providing a smooth ride for passengers. The stabilization technique eliminates the need for extraneous sensing mechanisms placed in or on the water surface which are subject to fouling, damage, or disruption by localized surface disturbances.
