You are at sea on a vessel that has a beam of 50 feet, and you calculate the period of roll to be 22 seconds. What is the vessel's metacentric height?

Correct Answer: Option B — 1.0 ft

Metacentric height (GM) is calculated using the standard USCG rolling period formula: GM = (f * B / T)^2, where breadth (B) is 50 feet and roll period (T) is 22 seconds, using the standard constant factor f ≈ 0.40, resulting in 1.0 ft.
