SUPERCRITICAL PLANING HULLS

The intolerable pounding of conventional planing hulls is the chief reason for the development of alternative hydrofoil and SES vehicles, in an attempt to achieve high speeds with motions that are commercially and militarily acceptable. Our approach has been to find out why a conventional planing hull pounds, and then to devise new planing hull forms which avoid the problem. Work over the last ten years, including a dozen experimental boats, has resulted in forms which largely meet this objective, we believe. Experimental data indicate that our latest hull--the Sea Knife--has a better ride than SES or surface-piercing hydrofoils and, for a much lower cost, is not much inferior to the fully submerged hydrofoil.
