n: the centre of gravity of the fluid displaced by a floating body (such as a ship or mobile offshore drilling rig).

n: a point located somewhere on a line drawn vertically through the centre of buoyancy of the hull of a floating vessel with the hull in one position (e:g., level) and then another (e.g., inclined). When the hull inclines to a new position, the centre of buoyancy of the hull also moves to a new position. If a second line is drawn vertically through the new centre of buoyancy, it intersects the first line at a point called the metacenter. Location of the metacenter is important because it affects the stability of floating vessels (such as mobile offshore drilling rigs).
