WebAug 17, 2024 · When a ship is inclined at an angle, the center of gravity remains the same. But the center of buoyancy changes over to a new position, creating a moment called righting moment. Righting moment … WebA Righting Moment is created by the ship to keep itself upright. In this case, the force is equal to the ship's displacement (W F) and the distance is the ship's righting arm (GZ) at each particular angle of heel. The Righting Arm (GZ) changes with inclination of the ship. Using the relationship derived in Unit 4.01 for small angles of heel:
