摘要： A boat pontoon having a concave V-shape on a bottom portion thereof, generally straight vertical sides, a flat top panel member, and a removable and replaceable skid pad running longitudinally along the bottom of the pontoon. Vertically oriented gussets are positioned on an interior of the pontoon, to provide structural integrity and additional strength. In a preferred embodiment, a buoyant foam is provided within the interior cavity of the pontoon.

摘要： The present invention relates generally to underwater wings for providing lift to boats. More particularly, the invention comprises an underwater wing that attaches to the hull or hulls of a pontoon or tri-toon boat. The purpose of the wing is to provide a designated amount of lift to reduce drag and improve performance of the watercraft. This is different from a traditional hydrofoil, which is designed to lift a boat completely out of the water.

摘要： A catamaran which has a centre tunnel, the opposite sides (105a, 105b) of which form asymmetrical pontoons, which are mirror images of each other, and which pontoons have buoyancy, which has been adapted so that when the catamaran moves in water, the centre tunnel functions as a combined water and air tunnel. When the catamaran is stationary in water, the ceiling (108) of the centre tunnel is in water. The ceiling of the centre tunnel further curves in a cylindrically convex manner downwards when going from the bow (116) to the direction of the stern (118) only after an essentially horizontal portion (401) of a distance (d), which essentially horizontal portion is located between the pontoons.

摘要： A three stage watercraft for operation in the water as a traditional boat at low speeds in stage one, for operation on the water's surface at mid-range speeds at stage two, and for traveling in ground effect at higher range speeds is disclosed. The three stage craft includes a hydro-wing 12, at least a single hydrofoil 13 to aid with lift from stage one to stage two, and a pair of outboard floats or hydro-floats 16a, 16b supported by the hydro-wing 12, which are also designed to aid with lift from stage one to stage two. A gyration rotor 14 to aid with lift from stage one to stage two may also be provided as may a pair of pivotally mounted air propellers which aid in lift and propulsion by varying their operational angle relative to the plane of travel of the craft.

摘要： Embodiments include a retrofit pontoon system including a pontoon, the pontoon having a pontoon body defining a first cavity, a retrofit assembly, the retrofit assembly including a first lateral tube, wherein the first lateral tube is sized to pass through a first aperture formed in the pontoon body and a selectively fillable container, where the first lateral tube is operably coupled with the selectively fillable container, a main tube, where the main tube is fluidly coupled with the first lateral tube, and a pump, the pump being coupled with the main tube such that operation of the pump selectively fills and drains water from the selectively fillable container, where filling the selectively fillable container lowers the profile of the pontoon in the water and emptying the selectively fillable container raises the profile of the pontoon in the water.

摘要： A lifting device for lifting and holding a small watercraft in a fixed position and that includes a support structure and a lifting mechanism. The support structure supports the lifting mechanism in a body of water, usually with some form of flotation device. The lifting mechanism is movable between a raised position that holds the watercraft steady and in a fixed position and a lowered position in which the watercraft is floating in the water. A handle bar assembly allows a user to maneuver the lifting mechanism between the positions.

摘要： A fiberglass pontoon boat, having raised and integrated fiberglass side rails, a flat floor, and a side entry level with the flat floor. Integrated seats are molded in fiberglass. The hull and deck join together by flexing the hull to compensate for opposing draft angles of the hull and deck at the side entry. The deck has a floor and at least one other interior component, and terminates in a deck trim flange. The hull has at least two hollow pontoons and at least two side rails that extend from an outer edge of the pontoons, and the hull terminates in a hull trim flange. When assembled, the hull trim flange operatively engages beneath the deck trim flange to form a unified pontoon boat having a space between the deck and hull and wherein the side rails are integrated as structural parts of the interior component.
