Maneuvering and Seakeeping Basin (MASK)

The Maneuvering and Seakeeping Basin is unique within the Navy, and is used to model the full scale motions of ships, platforms, and mooring systems in waves. In this facility, engineers evaluate the maneuverability, propulsion, dynamic stability, and control of surface ships and submarines in waves and smooth water at various headings. The MASK is used in measuring model motions, accelerations, control surface deflections, hull strains, and wake characteristics at a wide variety of simulated sea states through a radio-controlled surface and submarine model capability. The facility is also used for capsizing tests and slamming studies.
