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).

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 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.
Directional stability is stability of a moving body or vehicle about an axis which is perpendicular to its direction of motion. Stability of a vehicle concerns itself with the tendency of a vehicle to return to its original direction in relation to the oncoming medium (water, air, road surface, etc.) when disturbed (rotated) away from that original direction.
