Abstract: A hull form design which incorporates bi-lateral semi-sponsons disposed on either side of a non-stepped V-shaped center hull section. The semi-sponsons extend the entire length of the hull form and comprise protrusions extending away from the center section. The semi-sponsons are delimited by longitudinal steps extending below the hull bottom an equal distance from the centerline on opposite sides of the hull. This design is a hybrid of conventional “V” hulls and catamarans and improves the roll and turn initiation time of convention monohull designs.

Abstract: A watercraft comprising a bow, a stern, a hull, a transom, and a deck. The transom is located at the stern of the watercraft and the deck extends forward from the transom. One or more cavities are disposed through the deck adjacent to the transom wherein the cavities are each configured to receive an outboard motor. An enclosure is disposed over each of the cavities, providing a means to hide and enclose the outdoor motor. Multiple enclosures can be provided where the watercraft is powered by multiple outboard motors. The top of the enclosure includes a seating surface, providing a sun deck for boaters. The enclosures are hingeably mounted to the deck to provide selective access to the enclosure's respective cavity and motor therein. The interior of the enclosures defines a curved surface to promote air turnover inside the enclosures, optimizing engine performance.

Abstract: A T-step hull form for monohull planing vessels includes a forward section, an aft section, a transom, a step, and a skeg. The step is transversely oriented and separates the forward section from the aft section, and the skeg extends longitudinally along the length of the hull form from the step rearwardly to the transom, dividing the aft section into a starboard tunnel portion and a port tunnel portion. The starboard and port tunnel portions are ventilated at their respective outboard sides, at the transom, or both. Vents may pass transversely through the skeg. Tunnel flaps may be disposed in each of the tunnel portions and are hingeably attached at the step to allow for adjustability of the step's geometry. The addition of the skeg, which extends from the step to the transom, provides additional longitudinal surface area for the hull form, and in turn increases lateral stability.
