Angle of Loll

Angle of loll is a term used to describe the state of a ship which is unstable when upright (ie: has a negative GMt) and therefore takes on an angle of heel to either port or starboard.^[1][2][3][4]

It is often caused by the influence of a large Free surface or the loss of stability due to damaged compartments. It is different from list in that the vessel is not induced to heel to one side or the other by the distribution of weight, it is merely incapable of maintaining a zero heel attitude.
