WebThere are now two forces to consider: (W − P) acting upwards through M and (W − P) acting downwards through G 1. These produce a righting moment of (W − P) × G 1 M × sin θ. The original metacentric height was GM but has now been reduced to G1 M. Therefore, GG 1 is the virtual loss of metacentric height due to drydocking, or Example 1
