114610320 | Having specific bottom | 7 |
20130019789 | Boat Hull - A boat hull form includes a dual circular curved outer surface area that is circular concave relative to the plane of symmetry of the hull when viewed horizontally parallel with the plane of symmetry of the hull, and circular convex relative to the plane of symmetry when viewed vertically parallel with the plane of symmetry of the hull, with the hull outer surface area extending in a vertical sense from a lower area extending in a direction that tangentially intersects the plane of symmetry or optionally a plane extending parallel with the plane of symmetry on the same side of the plane of symmetry as the dual circular curved outer surface area and upwardly in a direction tangentially intersecting the waterline plane of the hull or a plane extending parallel to the waterline plane. | 01-24-2013 |

20130220193 | WAKESURFING BOAT AND HULL FOR A WAKESURFING BOAT - A wakesurfing boat and a hull for a wakesurfing boat. The hull includes a bottom having a preselected length extending from a bow to a stern. The bottom includes a central ridge and port and starboard ridges extending below respective port and starboard bulwarks to define a substantially M-shaped bottom with concave portions to port and starboard of the central ridge. Port and starboard sponsoons extend below the port and starboard bulwarks proximate the stern. A trim wedge projects below the stern. Two rounded stern portions are provided proximate the stern. In a dynamic surfing mode, with selectively-fillable ballast tanks partially or fully flooded, water flowing through the port and starboard concave portions, combined with the ballast, increases resistance to the hull, resulting in a larger wake wave. Water passing around the structural features proximate the stern is directed toward a convergent zone in the wake, resulting in an improved wake wave shape. | 08-29-2013 |

20140338579 | ELLIPSOIDAL V-HULL - An improved boat hull design includes a region of ellipsodal fulness in the forward portion of the hull, ellipsiodal curvature over the remainder of the hull, a chine with a chine flat with an increasing width as it approaches the stern and one or more strakes. One of the strakes is located where the chine flat meets the V portion of the hull. The hull provides stability and a smooth ride at both high and low speeds in smooth and rough water and is highly maneuverable. The hull also has good weight carrying ability at speed while not requiring excessive power. The hull minimizes rolling when stationary or at low speed in waves. | 11-20-2014 |
