(shipbuilding) the point of intersection between two vertical lines, one line through the center of buoyancy of the hull of a ship in equilibrium and the other line through the center of buoyancy of the hull when the ship is inclined to one side; the distance of this intersection above the center of gravity is an indication of the stability of the ship
- The intersection of vertical lines through the center of buoyancy of a floating body when it is at equilibrium and when it is floating at an angle. The location of the metacenter is an indication of the stability of a floating body.
- Transverse metacenter above the base line
- Transverse metacenter height above base line
- Height of metacenter above the center of buoyance
- keel metacenter
- locus of metacenter
