Class Information
Number: 114/283
Name: Ships > Hull or hull adjunct employing fluid dynamic forces to derive a lift or alter trim, (e.g., planing hulls, etc.) > Having laterally disposed skids or pontoons
Description: Device wherein a plurality of floats or surface skimming members are either connected together in a spaced, side-by-side fashion to form a vessel or they are connected to, but spaced from either side of a vessel’s hull in such a manner that they coact with the water to at least partially support the weight of the vessel and thus allow the vessel’s hull to raise up in the water when the vessel is under way.
