Your vessel measures 119 feet long by 17 feet in beam. If the natural rolling period at a draft of 5'-05" is 6 seconds, what is the GM?

Correct Answer: Option C — 1.55 feet

Applying the rolling period formula GM = (f * B / T)^2 with a 17-foot beam and 6-second roll period produces a metacentric height of 1.55 feet.
