1401. Your vessel measures 126 feet (38.41 meters) long by 21 feet (6.4 meters) in beam. If the natural rolling period at a draft of 8 feet (2.44 meters) is 6 seconds, what is the GM?

Calculate GM using the formula GM = (0.44B/T)2, where B is the beam and T is the rolling period. Substituting B = 21 feet and T = 6 seconds yields GM ≈ 2.4 feet, which corresponds to 0.70 meters.
