  • Patent number: 9027498
    Abstract: A watercraft body includes a hull made of an aluminum-based material and a separately fabricated superstructure that is mounted on the hull via adjoining flange plates. To fabricate the hull, frame elements are spot-welded onto the inner surface of initially-flat hull plates or plank elements, which are then curved according to the required hull contour and assembled onto the flange plate. The frame elements are screwed together via gusset plates and transverse beams to form transverse frames, and then longitudinal seams between plank elements are continuously welded from the outside. Additionally, the longitudinal seams may be welded from the inside, for example by temporarily removing gusset plates to allow continuous access to the longitudinal seams. Additionally, stand-offs may form a spacing gap between the frame elements and the plank elements, and an adhesive may fill this spacing gap to adhesively bond the framework to the hull plating.

  • Patent number: 8714099
    Abstract: A pontoon framing system using complimentary cross members and pontoons to form a pontoon frame. Making the pontoon is done by providing a flat sheet of material that has lateral edges. Rectangular notches extending inwardly at lateral edges are located opposite each other. The sheet is rolled into a cylinder so the notches in the sheet form a notch into the final cylinder that forms a central portion to the pontoon. The lateral edges are joined, and this is typically done by welding. A cross member having a rectangular cross section is placed into the notch formed in the cylindrical central portion. The cross member is then joined to the cylinder. The complimentary shape of the cross member and pontoon may also be produced by having a cylindrical central portion and then removing an arcuate portion of material in the cross member to match the shape of the pontoon.

A pontoon is described which features an outer shell comprised of an aluminum or aluminum alloy shell enclosing one or more water-tight chambers. The shell has an exterior surface, and one or more runners are provided upon the exterior surface which serve to both reinforce the pontoon and guide the endless chain system which drives the cleated tracks which surround the pontoon and serve to propel the vehicle. The runners are comprised of at least one longitudinal strip. The strip is disposed along and fixedly attached to the lower surface of the pontoon shell. Preferably, the strip is comprised of an aluminum or aluminum alloy-type material and is fixedly attached by means of welding to the shell. A longitudinal channel member, preferably made of steel or a steel-type alloy is disposed proximate the strip.

  • Patent number: 5349917
    Abstract: A unitary aluminum watercraft is constructed from a single sheet of deep-formable aluminum by forcing a mold into the sheet to imprint the mold into the sheet and then forcing the perimeter portions around the mold. Excess sheet material is removed and than placed into a replica mold. A deck is installed and bonded to the interior bottom surface of the body by a structural flotation foam, such as urethane, to form a unitized structural beam which eliminates the need for a keel and the accompanying structural ribs and below-waterline rivets usually required.

  • Patent number: 5277720
    Abstract: The present invention discloses a method of preventing detrimental adherence to and buildup of living marine organisms on exposed surface areas of a preselected component which is subjected to contact with a fluid medium that contains certain marine organisms. The methodology comprises the steps of preparing that portion of the component's exposed surface which contacts the fluid medium in a manner which will enable the adherence of a preselected anti-fouling agent to at least a portion of that exposed surface. After preparation, the preselected anti-fouling agent is applied.

  • Patent number: 5035759
    Abstract: The present invention relates to an improved method of protecting the hulls of marine vessels from fouling. The inventive method involves the application of thin metallic films to the hull of a boat. The inventive method includes the use of various techniques for application of the film, techniques for preventing the touching of dissimilar metals, techniques for insuring that dissimilar metals are insulated and isolated from one another, insuring that active or passive cathodic protection systems are not on the same surface plane as the attached films and other techniques. The specific materials which are applied to the vessel hull as well as their various parameters in the environment of the present invention are disclosed. Specific treatments to the thin metallic film to improve the adherence of these thin film hulls and adjacent films are disclosed.

  • Patent number: 4993350
    Abstract: A pontoon log is formed by welding the upper flanged edges of a U-shaped hull member to the side edges of a flat top plate. At points at which the deck beams are to be attached to the log, the log top plate is notched and the weld is continued around the perimeter of each notch. The deck beams are bolted to the pontoon log with the bolts passing only through the hull flange in the region of the notches and hence outboard of the weld line. The modified embodiments, various types of spacers and clips are provided to reinforce the hull flange in the region of deck beam attachment.
