  • The free surface effect of a liquid's movement within a ship raises its virtual centre of gravity and consequently reduces the transverse metacentric height.3 Since metacentric height is a principal indicator of a ship's initial ability to remain upright, the elimination or reduction of free surface is essential in maintaining a vessel's stability.
