329. Your vessel has a displacement of 24,500 tons. It is 529 feet long and has a beam of 71 feet. You have timed your vessel's rolling period to be 25.0 seconds. What is your vessel's approximate GM?
Metacentric height (GM) is calculated using the formula GM ≈ (0.44 * beam / rolling period)2, resulting in an approximate value of 1.56 feet for this vessel.
