To evaluate methods to obtain high speed at sea without large increases in ship size, several hull configurations were surveyed, in particular semisubmerged craft designed to operate at or just below surface; by increasing amount of submerged hull volume, both high speed resistance and pitching motions in rough seas can be reduced; forms surveyed include craft that resembles surfaced submarine, slender ship with large bow and stern bulbs, and craft (semisubmerged) that is similar to shallow running submarine with permanent surface piercing strut for air supply and exhaust.
