A ship's ability to automatically right itself after leaning hinges on the relationship between its center of gravity and the shifting center of buoyancy, a distance known as the metacentric height or GM. When a stable hull tilts, the upward push of buoyancy shifts off-center to counteract the downward pull of gravity, creating a powerful righting lever that snaps the vessel back upright.
Engineers calculate this crucial stability metric using a precise formula that weighs the moved deck mass, horizontal distance, overall displacement, and the resulting angle of heel. If a ship's center of gravity rises too high, the metacentric height disappears entirely, leaving the vessel completely defenseless against a sudden turn or a passing wave.
