173. Your vessel's has a beam of 60 feet, and you observe a still water rolling period of 25 seconds. What is the vessel's metacentric height?
The metacentric height is calculated using the formula GM = (0.44B/T)2, where B is the beam and T is the rolling period. With a beam of 60 feet and a rolling period of 25 seconds, the metacentric height is approximately 1.1 feet.
