  • Patent number: 10745084
    Abstract: A system for enhancing a wake profile produced by a pontoon boat is provided. The system includes a pair of ramps attached to the bottom of a platform supported by at least two pontoons. The ramps may be oriented downward with a rear end of the ramp disposed in the water between the pontoons. The water flowing between the pontoons is displaced downward by the ramps, thereby increasing water displacement and directing the water to produce an improved wake profile. Downforce may be applied to the boat by one or more wake plates, with a faceted portion of the wake plate facing forward and upward, such that when water impacts the faceted portion a downforce is provided. The wake plates may be attached to the ramps or may be separate from the ramps.

    Abstract: This invention is type of dual-purpose boat, including cabin and hull. This boat is unique in that between the cabin and hull there is a lifting mechanism connecting the hull and cabin, at least one of which has been set up with a buoyancy regulating structure. This invention can be used as a regular boat, or if the cabin is lowered, this invention becomes a semi-submerged vessel that can be used for operational purposes or underwater sightseeing. When the invention enters shallow water or needs to navigate at high speed, the cabin can be raised to prevent beaching and to reduce resistance. The operation of this invention is simple and expands the single function of current boats.

The pontoon boat includes a substantially enclosed storage space defined at least in part by a portion of the deck and a portion of the wall assembly. The wall assembly has a bottom edge that is spaced off of the deck to provide a first air access opening into the storage space from beneath the wall. At least one vent is provided in the wall portion at a location spaced above the bottom edge and in open communication with the storage space. The vent enhances air flow and venting of the storage space.

  • Patent number: 8543256
    Abstract: According to typical practice of the present invention, a vehicle is remotely controlled and is travelable both in water and on land. The vehicle has two liquid-containment components that are situated generally one above the other. Pumping devices bring about transfer of cargo liquid (e.g., fuel or water) from either component to the other component. In accordance with the liquid transfer, the vehicle turns over, about its longitudinal axis, between two generally opposite buoyant positions, each of which is stable and viable for marine navigation. When the flow of the liquid sufficiently shifts weight from one component to the other, the vehicle inverts; that is, the emptying component flips from the bottom to the top, and the filling component flips from the top to the bottom. One of the buoyant positions of the vehicle is characterized by wheels for amphibiously transitioning the vehicle from water travel to land travel.

  • Patent number: 8430045
    Abstract: An onboard lift leg construction for a pontoon boat has a plurality of movable support legs including rear telescoping tube support legs that are fixed to a frame of a pontoon boat. The telescoping tube support legs each include an outer tube fixed to the frame, and an inner tube slidably mounted within the outer tube. A linear hydraulic actuator is secured to a head member that is supported on the outer tube. The actuator has an extendable and retractable rod that is attached or secured to the lower end of the inner tube such that when the actuator is extended, the inner tube is also extended to effectively lift the pontoon boat to which the outer tube is attached. The forward portions of the pontoon boat frame can be provided with pivoting lift legs for lifting the pontoon boat.

    Abstract: A tensioning device is described for a carrying net (6), in particular between the hulls (1) of a catamaran, the carrying net (6) being fastened in a tensile-resistant manner to two mutually opposing legs of a tensioning frame. In order to attain advantageous tensioning conditions, it is proposed that one of the two legs be mounted, as the tensioning leg (5), in the tensioning frame so as to be rotatable about a pivot shaft (10) which is parallel to its longitudinal axis, the pivot shaft extending, when the carrying net (6) is tensioned, on the net side at a distance from the run-off line (13) of the carrying net (6) from the tensioning leg (5), and that an interlocking means (15) be provided for the tensioning position of the tensioning leg (5).

  • Publication number: 20120304909
    Abstract: New design of vessel with submersible hulls which can transport large cargos at high speed sailing above the waves and which is made up of two parallel submerged bodies (4), clearly cylindrical in cross-section or as hydrodynamic as possible, joined by hydrodynamic profiles (5). Four hydrodynamic legs (3) are located in the confluence between the cylinders (4) and the profiles (5) capable of supporting a platform or loading zone (2) which can move (up or down) on the legs (3) which have a system of vertical displacement so as to raise itself above the level of the waves. The parallel bodies of submerged displacement (4) joined to the hydro-dynamic profiles (5) can be completely covered with a textile of permeable sheets of porosity less than the size of a molecule of water and greater than that of a molecule of air and air can be pumped into the interior.

  • Publication number: 20120291686
    Abstract: A watercraft hull has a flat pad keel whose beam tapers towards the bow and at the transom is 15% to 25% of the beam at its chines. The hull is symmetric about its centerline, has a fine entry bow, and a pair of hard chines. Between the pad keel and the chines the hull has at least one pair of generally flat longitudinal steps having approximately 0 degrees of deadrise forming planing surfaces symmetrically about the hull centerline. The hull also includes at least one pair of ultra high deadrise panels, outboard of and adjacent to the pad keel, symmetrically about the hull centerline, and extending to the flat planing panels above them. The ultra high deadrise panels have a deadrise approximately 50 degrees. Additional flat planing surface structures having approximately 0° deadrise are installed longitudinally on the hull between the pad keel and the hard chine.

  • Patent number: 8312828
    Abstract: The present invention reduces loads and saves steel on topsides and grillage of a catamaran system by creating a lifting force from a barge to the topsides to offset a sagging bending moment of the self-weight on the topsides during transportation. The present invention can reduce the span of the supports on the topsides on the catamaran float-over barges and move the reaction forces toward inner edges of the float-over barges. The lifting force can cause a reduction of stress on the topsides' and grillage's members caused during the topside offloading and transportation. The stress reduction can result in the members withstanding the additional dynamic load caused by a catamaran system without increasing member sizes adequate for an offloading operation. The reduction results in a significant savings, given the size of a typical topsides for a Spar hull or other offshore structure.
