Stephen Ditmore, Dec 31, 2001 #4. Joined: Dec 2001 WebAs the ship is inclined, the center of buoyancy moves in an arc as it continues to seek the geometric center of the underwater hull body. This arc describes the metacentric radius. As the ship continues to heel in excess of 7-10 degrees, the metacenter will move as shown.

Now shift the weight ‘w’ forward through a distance of ‘d’ meters. The ship’s center of gravity will shift from G to G 1, causing a trimming moment of W × GG 1, as shown in Figure 18.3(b). The ship will trim to bring the centers of buoyancy and gravity into the same vertical line, as shown in Figure 18.3(c).
