You are on a vessel that has a metacentric height of 4 feet, and a beam of 50 feet. What can you expect the rolling period of the vessel to be?

Correct Answer: Option D — 11.0 seconds

The approximate rolling period formula is T = (0.35 * Beam) / square root of GM. Substituting a 50-foot beam and a GM of 4 feet yields 17.5 divided by 2, resulting in an 11.0-second rolling period.
