William F. Hulbig has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Watercraft and hull systems
    Patent number: 6065414
    Abstract: The invention includes new hull systems and watercraft. In particular, the invention provides a watercraft hull (10) that has a pivot axis (22) forward of the hull waterline fore-aft center line (24). That pivot axis (22) will be the deep water point of the hull and provides a fulcrum point around which the hull turns during a direction change. The forward pivot axis (22) surprisingly imparts high manoeuvrability (i.e. the ability to execute turns of reduced radius) relative to prior systems, even at low speeds.
    Type: Grant
