Number: 114/288
Name: Ships > Hull or hull adjunct employing fluid dynamic forces to derive a lift or alter trim, (e.g., planing hulls, etc.) > Having fluid channeling or entrapping configuration
Description: Device wherein the hull of the vessel is either so contoured or accessories are so attached thereto that (a) a groove-like configuration is formed in the bottom of the vessel which runs generally parallel to the keel, or (b) a space is formed within which a gas or liquid is captured or confined, whereby a lifting force is generated as fluid either courses through the groove or is captured in the fluid confining space.
