What (who) is metacentric height - definition


Metacentric height         
  • Initially the second moment of area increases as the surface area increases, increasing BM, so Mφ moves to the opposite side, thus increasing the stability arm. When the deck is flooded, the stability arm rapidly decreases.
  • Distance GZ is the ''righting arm'': a notional lever through which the force of buoyancy acts

The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre.
