Should the ship's center of gravity (G) coincide with (M) and an external force be applied, the ship will assume an "angle of loll." The ship will maintain the assumed angle until a further force is applied. Should another external force be applied, the ship may assume an angle of loll to the other side or may worsen the existing loll condition if there is no righting lever, GZ, to correct the assumed heel angle. In this condition the ship is said to have zero or no GM (see Figure C-2).
