Angle of Loll

The Angle of Loll is the angle or range over which a vessel has negative metacentric height or (GM) while upright. This vessel will tend to heel to port or starboard,or alternate back and forth in an unstable manner. As the vessel heels over it will pass beyond the angle of loll and reach a state of "stable" equilibrium. At this point the vessel may appear to be a stable but, a course of action should be taken to remedy this situation and ensure the boat has more acceptable initial stability values.
