How Icon of the Seas Stays Upright—and What Size Cannot Tell You

How does Icon of the Seas stay upright when most of its volume sits above the waterline? Its stability depends on the relationship between its centre of gravity and metacentre—not on its size or weight. Learn what the international maritime rules require ships to prove. Understand cruise ship stability through metacentric height, righting-arm curves and the forces generated by stabiliser fins. Gross tonnage describes internal volume: calling a vessel the largest cruise ship does not establish its stability margin. The payoff is knowing how to distinguish a stability mechanism, a minimum requirement and a vessel’s own results. This episode explains generic fin operation, but the approved evidence does not establish Icon’s fin equipment, ballast arrangements, actual metacentric height or righting-arm curve. Its stability margin remains unquantified here.
