Your vessel has a metacentric height of 1.12 feet and a beam of 60 feet. What will your average rolling period be?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 25 seconds
Applying the standard rolling period equation T = (0.35 * B) / sqrt(GM) with a 60-foot beam and a 1.12-foot metacentric height yields 21 divided by 1.058, resulting in an average rolling period of approximately 25 seconds.
