The document discusses the phenomenon of loll in ships, where a ship floats at an angle to one side or the other due to being unstable in an upright position. Loll can be caused by a large area of free surface inside the hull or a large addition of top weights. There are four ways to reduce loll: removing weights from high up in the ship; reducing the area of free surface liquid, especially breadth; adding weight low down in the ship; and shifting weights from high in the ship to lower levels.
