The oscillation of a ship in still water

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. WebbThe oscillation of a ship on rough sea can be modeled as a floating cylinder on water, with the water level itself also rising and falling in simple harmonic motion y=y o sin (wt), …

WebbIn a normally loaded vessel any rolling from perpendicular is countered by a righting moment generated from the increased volume of water displaced by the hull on the lowered side. This assumes the center of gravity of the vessel is relatively constant.
