ABSTRACT:
An improved performance and high stability marine surface vessel that is supported at least in part by a pressurized gas cushion where the pressurized gas is supplied to the gas cushion normally by mechanical apparatus such as a powered blower. The pressurized gas cushion is restrained, at least partially, by a recess built into the underside of the hull with significant advancements including a forwardly extending bow member that helps lift the bow over rough seas, water impact relief openings in the side hulls, movable and optionally remotely controllable stern seal member sections that allow control of recess gas cushion depth, pressure and other gas cushion characteristics, and a control system for a movable stern seal member. The advancements also include a forward movable seal attached structure that greatly increases movable seal life. The above advancements may be used singularly or in various combinations.
