A watercraft as in claim 1 wherein the longitudinal profile of the hull has a substantial rise in the keel line from the middle section to the bow and a smaller rise in the keel line from the middle section to the stern.

The semi-displacement hulls of this invention are generally characterized by a ratio of the maximum beam of the hull to the maximum depth of the hull of 2.5:1 or greater.

 M-hull
The M-shaped hulls are designed to recapture the bow wave in order to use bow wave energy to create an air cushion for reduced friction drag.
In sea trials of a boat embodying such a hull, the act of increasing power to test the advantages of the air planing cushion at higher boat speeds led to the discovery of two new phenomena.
The first and second channels are adapted to capture a bow wave and to cause air and water to mix and spiral toward the aft end of the hull as compressed aerated water, thereby reducing friction drag, increasing lateral stability, and dampening transmission of bow wave energy at the aft end of the hull.
