The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. Metacentric height also has implication on the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently high but not excessively high metacentric height is considered ideal for passenger ships.

Famous quotes containing the word height:
“Much more frequent in Hollywood than the emergence of Cinderella is her sudden vanishing. At our party, even in those glowing days, the clock was always striking twelve for someone at the height of greatness; and there was never a prince to fetch her back to the happy scene.”
—Ben Hecht (1893–1964)
