 Met·a·cen·ter or Met·a·cen·tre, n.  Hydrostatics The point of intersection of a vertical line through the center of gravity of the fluid displaced by a floating body which is tipped through a small angle from its position of equilibrium, and the inclined line which was vertical through the center of gravity of the body when in equilibrium.

 metacentre
      n : (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 [syn: metacenter]
