114292000 | Pontoon structure | 6 |
20090031939 | Pontoon boat having improved buoyancy - A pontoon boat is shown which includes a frame, and a plurality of pontoons attached to the frame. The plurality of pontoons comprises two outer pontoons of substantially cylindrical configuration and a center pontoon comprising a substantially curvilinear configuration, wherein a height of the center pontoon is substantially equal to the diameter of the outer pontoons. One embodiment of the pontoon is elliptical in cross section. | 02-05-2009 |
20090133614 | Water skimmer - A small outboard motor powered boat comprises a hull undersurface that defines a generally flat central section, with two generally parallel-sided pontoons extending rearwardly from an upturned bow to a point about half the length of the hull aft. A stern rake section begins at a transverse line near the transom of the hull and forms a downward angle with respect to the flat central section. At speed, air is entrained between the pontoons, providing lift to the bow of the vessel, while the after portion is supported by the stern rake section. Thus, the vessel effectively rides on the pontoons and the stern rake section, reducing wetted surface and thus improving efficiency. The downwardly-extending lengthwise sides of the pontoons provide lateral surface, providing good steering characteristics. | 05-28-2009 |
20090194015 | PROFILED PONTOON FOR WATERCRAFT - A pontoon for a watercraft. The pontoon has a vertical inboard side and a generally angled bottom defined by the inboard side height of the pontoon being greater than its outboard side height. The bottom has planing surfaces that define one or more channels, which produce lift upon the watercraft increasing its speed on water. An inboard horizontal planing surface allows relatively low speed planing. | 08-06-2009 |
20090301376 | PLANING PONTOON TUBE - An improved water tight, chambered planing pontoon assembly incorporates a hollow shell with a cross sectional shape in the form of an upper portion and lower portion. The upper portion of the shape is generally semi-cylindrical extending downward and terminates with opposing chines extending the full length of the tube. The lower portion of the shape is formed by equal and opposing planing surfaces which extend upward at acute angles from a vertical center line, then turn outward, perpendicular to the vertical center line, meeting at the chines. The tube terminates on the bow end with an elongate semi-cone and on the opposite end with a water tight bulkhead. The upper and lower portions of the tube are formed of one homogeneous sheet of metal. The semi-cone with opposing chine portions is formed of one homogeneous sheet of metal. | 12-10-2009 |
20110132251 | Pontoon planer - The pontoon planer is a planer assembly for a pontoon boat that includes a pair of planer foils attached to the undersurface of the boat. Each foil presents a wedge-shaped profile, and a respective foil is disposed between the motor mount and a respective pontoon. The planers function to channel water in a downward direction to provide a lifting force to allow the pontoons to plane at lower speeds. | 06-09-2011 |
20140048006 | Side force enhancer for planing objects - Applicant's Side Force Enhancer for use with a slender planar object which hydrodynamically planes proximate to the interface of a liquid and gas environment. The side force enhancement device comprises a plate having an inner surface and outer surface terminating at an upstream leading edge and downstream trailing edge, said plate mounted to the upper surface of said planar object at a predetermined location along the length of said planar object's side edge. The side force enhancing plate's upper most surface is positioned a predetermined distance below the upper surface of said planar object, said plate's lower most surface positioned a predetermined distance below said planar object's lower surface. The inner surface of said plate is proximate to said planar object's side edge, defining an angular relationship therewith. Said plate has a preferred length to height ratio and said angular relationship defines a preferred range of angle. The gap between the plate and said planar object, its angle with said planar object's side edge and yaw axis influences the maneuverability of said planar object at the liquid gas interface as a function of speed and pitch. | 02-20-2014 |
