- Q133 - Deck Safety: Stability Problems
63. You are loading cargo on deck aboard a vessel whose beam is 60 feet and full period of roll is 20 seconds. What is the estimated metacentric height of the vessel?
The metacentric height (GM) is estimated using the formula GM = (0.44 * B / T)2, where B is the beam and T is the roll period. With a beam of 60 feet and a roll period of 20 seconds, GM is approximately 1.7 feet, which aligns with the correct answer.
