Abstract:
A twin-hull vessel apparatus, comprising:a cross deck; first and second hulls secured to the cross deck in spaced relation, each of the first and second hulls extending downward from the cross deck into a surface of a body of water, each of the first and second hulls further having an upper hull portion secured to the cross deck, a wave impact hull portion secured to the upper hull portion in proximity to the waterline, and a lower buoyancy hull portion secured to the wave impact hull portion at a location below the waterline; an open pipe conduit secured to each of the lower buoyancy hull portions, said open pipe conduits each having open front and back ends, said front end serving as an inlet nozzle for water passage through the open pipe conduit, said open pipe conduit extending horizontally in a direction parallel to a direction of propulsion of the multi-hull vessel; the upper hull portion tapers inwardly on each side about a hull centerline towards the wave impact hull portion, and the lower buoyancy hull tapers outwardly on each side about the hull centerline from the wave impact hull portion to the open pipe conduit; and said upper hull, wave impact hull, and lower buoyancy hull are designed as thin, wave piercing hull shapes.
