ABSTRACT:
The specification discloses a modified V-hull for a boat in which an elongate pad forms the lowermost portion of the hull. At positions toward the front of the pad, it has a transverse cross-sectional rounded V-shape across its width, but at the back of the pad, the transverse cross-section is almost flat. The pad has a gradually increasingly acute V-shape in transverse cross-section from the back to the front of the pad, and the pad is linear along linear tracks extending from about the longitudinal center (the keel line) of the elongate pad rearwardly at a track angle with respect to the longitudinal center of the pad. The track angle remains approximately constant from about the back to the front of the pad. Also, the pad is linear at its rear end along an infinity of tracks extending from a point on the pad's longitudinal centerline about three feet from the back of the pad to any point on the back of the pad. To provide lift, the pad has horizontal strakes of about one-half inch in width along the longitudinal edges thereof.
