m80

The M80 Stiletto is an American prototype naval ship using advanced stealth technologies. The M80 is produced by American marine engineering contractor, the M Ship Company, as an experimental testbed ship for The Pentagon’s Office of Force Transformation. It is notable for its innovative Pentamaran hull design and advanced carbon fiber composite construction. The Stiletto is being tested by the United States Navy SEALs and Special Warfare Combat Crewmen, in rough littoral seas.
Historically, ships have evolved to become narrower and deeper to achieve speed and stability. Instead (like other multihulls) the M Hull uses its width to gain stability. Its five slim hulls create virtually no bow wave, thus obviating the "hull speed' limitation of displacement craft. The Stiletto's "double-M hull" enables the craft to achieve a remarkably steady ride in rough seas at high speed, which makes the ride more comfortable and safer for military passengers. A disadvantage is that the five hulls give a large "wetted area", increasing drag.
