    • ‘This distance is called the metacentric height, which takes negative values when the center of mass is above the center of buoyancy, as is common among fishes.’
    • ‘When a ship heels, the center of buoyancy B moves away from the centre-plane, and hence it creates restoring moment around the centre of gravity G.’
    • ‘This is difficult to do since the center of your body mass is about 6 inches above your navel, but your center of buoyancy is between your armpits.’
