M m - noun metacenter the intersection between two vertical lines, one through the center of buoyancy of a hull in equilibrium, the other through the center of buoyancy when the hull is inclined slightly to one side or toward one end: the distance of this intersection above the center of gravity is an indication of the initial stability of the hull. 1
- noun metacenter The point of intersection between a vertical line through the center of buoyancy of a floating body such as a ship and a vertical line through the new center of buoyancy when the body is tilted, which must be above the center of gravity to ensure stability. 1
- noun metacenter that point in a floating body at which a vertical line drawn through its center of buoyancy when it is upright meets the vertical line drawn through its center of buoyancy when it is tipped; center of gravity of the part of a floating body that is not submerged: for stability the metacenter must be above the center of gravity 0
