"WebbWhen a ship is floating at rest in still water, the force of buoyancy (B) acts upwards in a vertical line from a single point which is resolved at the transverse centre of the displaced water volume. When the same ship is then inclined by an external force and heels to a small angle, a buoyancy wedge will cause B to shift to the low side. " - The oscillation of a ship in still water
