Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity , centers of buoyancy , the metacenters of vessels, and on how these interact.
Ship stability – Ship response to disturbance from an upright condition; Ship motion test – Scale model a hydrodynamic test to predict full size behaviour; Six degrees of freedom – Types of movement possible for a rigid body in three-dimensional space; Flight dynamics – Study of the performance, stability, and control of flying vehicles
The stability conditions of watercraft are the various standard loading configurations to which a ship, boat, or offshore platform may be subjected. They are recognized by classification societies such as Det Norske Veritas , Lloyd's Register and American Bureau of Shipping (ABS).

Ship stability diagram showing centre of gravity (G), centre of buoyancy (B), and metacentre (M) with ship upright and heeled over to one side. As long as the load of a ship remains stable, G is fixed (relative to the ship). For small angles, M can also be considered to be fixed, while B moves as the ship heels.
USS George Washington Carrier Strike Group underway in the Atlantic USS Constitution under sail for the first time in 116 years on 21 July 1997 The United States Navy has approximately 470 ships in both active service and the reserve fleet; of these approximately 50 ships are proposed or scheduled for retirement by 2028, while approximately 95 new ships are in either the planning and ordering ...
Ship stabilizing gyroscopes are a technology developed in the 19th century and early 20th century and used to stabilize roll motions in ocean-going ships. It lost favor in this application to hydrodynamic roll stabilizer fins because of reduced cost and weight. However, since the 1990s, there is renewed interest in the device for low-speed roll ...
The 2008 version of the Code details guidelines on Second Generation Intact Stability for ships, specifically criteria for dynamic stability and damage assessment. [7] The Code is split into two parts. Part A contains mandatory criteria. Part B contains additional guidelines and recommendations. [4]
