This can be seen in the form of metacenter the point at which the upward buoyancy force … When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre. The metacentre remains directly above the centre of buoyancy by definition. In the diagram above, the two Bs show the centres of buoyancy of a ship in the upright and heele… lights for covered patio
