Question 2522Deck Safety70% to pass
Your vessel measures 127 feet long by 17 feet in beam. If the natural rolling period at a draft of 7'-10" is 5 seconds, what is the GM?
AI Explanation
The correct answer is A) 2.24 feet.
The formula to calculate the metacentric height (GM) based on the vessel's natural rolling period and draft is: GM = (T/(2π))^2 * (L/B), where T is the natural rolling period, L is the vessel's length, and B is the vessel's beam.
Plugging in the given values, we get: GM = (5/(2π))^2 * (127/17) = 2.24 feet.
The other options are incorrect because they do not match the calculated value of 2.24 feet using the formula and the provided vessel dimensions and natural rolling period.
