A term used to describe the state of a ship which is unstable when upright and as a result floats at an angle of heel on one side or the other. It is usually caused by a large area of free-surface water inside the hull, as for instance a ship with flooded compartments, but can also be caused by too much weight carried high up in the ship. It is not the same as list, which is caused by quite different conditions. Loll in a ship can be reduced by removing top weight, adding to bottom weight, or by reducing the area, and particularly the width, of the free-surface water in the ship.
