The invention is an air propelled boat that has a triangular shaped hydroplaning monohull which has surface adhesion characteristics by means of a concave bottom hull. The invention also has aircraft-like control surfaces (5,6) for safety and control at high speeds. The invention is the only monohull marine craft which produces aerodynamic lift without wings and has air based propulsion (4), air based control surfaces and a unique concave planing hull.

An anti-wave floating photovoltaic device comprises a folding panel frame, an elastic support leg, a buoy and a self-locking support rod. The folding panel frame includes multiple unit frames and configured to be folded or unfolded by Miura folding. The adjacent unit frames are connected by a hinge mechanism and a photovoltaic panel is provided on the front side of the folded panel frame. The elastic support leg includes a V-shaped support rod and a U-shaped support rod with a changeable opening and providing elasticity through springs. The buoy includes a power buoy, an intermediate buoy and a driven buoy. The power buoy connects the intermediate buoy and the driven buoy through a rod.

This invention relates to a generally molded fiberglass apparatus that serves a multipurpose function for inflatable boats. The apparatus attaches to the bow of the boat and includes a forward passenger seat with a backrest and optionally servers to provide a step for embarking or disembarking the boat at the bow, and location for affixing one or more marine navigational or safety devices or accessories. The invention is affixed to the inner bow section of the passenger area to an inflatable tubular member craft by a permanent or semi-permanent means including, but not limited to clamps, adhesives, bolts, clips, snaps, ties, ratchets, or a combination thereof. The apparatus is shaped to conform to the topside bow curvature of the inflatable boat and to the adjacent concave curvature on the substantially vertical section within the passenger area at the bow of the inflatable boat, utilizing the craft's structure as the seated area.

An internal canoe frame acts as a mount for retractable outriggers, foldable panels, and pontoons. With the outriggers, panels, and pontoons, the canoe can be adapted to provide a stable multi-purpose waterborne platform. In some embodiments, the platform may also include a support frame for a tent, to provide a waterborne camping site for an intrepid canoer.

This invention relates to a naval rescue vessel, comprising a propulsion unit (1) powered by a water jet and a hull unit (200), wherein said hull unit is at least partly flexible and wherein said propulsion unit (100) is arranged to form a rigid unit, and wherein the two units (100, 200) are interconnected to form a naval rescue vessel intended to be handled/maneuvered by a single rescuer, wherein the interconnection (130, 205) between the two units (100, 200) is arranged to provide a releasable connection of the units.

A dual air chamber structure having two independent and air impervious chambers, with each chamber being inflated and deflated by a separate air valve. The inner chamber, except for its air valve, is completely contained by the outer chamber and is comprised of primary horizontal conduit and a plurality of inflatable intermittent vertical posts made of small diameter tubing which are connected by a corresponding plurality of horizontal conduit made of small diameter tubing, such that the inner chamber as a whole is comprised of a repeating series of inflatable vertical posts followed by inflatable horizontal connectors. The outer chamber forms an air impervious bladder around the inner chamber, except for the air valve of the inner chamber.

A twin hull foldout watercraft that quickly and easily deploys from a small mobile and portable size unit that will fit into a vehicle or stow in a closet, camper or larger boat to a dry stable watercraft that could be used with small motor, paddles, ores, stand up paddles, push poles or sail and which has all parts and accessories attached thereto. The twin hull foldout watercraft comprises a central deck, two side mounted hull flaps hingedly attached to the opposing side edges of the central deck and positionable in a vertical or horizontal position, a fore deck extension member hingedly attached to the front edge of the central deck and positionable in a vertical or horizontal position, and an aft deck extension member hingedly attached to the rear edge and which can be extended out from the rear of the central deck.
