        "note": "The metacentric height GM = KM − KG is the single most important initial-stability number: the height of the metacentre (set by the hull form and draught) above the centre of gravity (set by loading). Positive GM means the ship returns upright; negative GM means it lolls or capsizes. Too small is dangerous, but too large gives a violent, cargo-damaging roll — naval architects aim for a comfortable middle.",
