Question 2520 Deck Safety

The correct answer is A) 1.38 feet. The reasoning is as follows: The formula to calculate the metacentric height (GM) based on the natural rolling period is GM = (T^2 * L) / (0.0884 * B), where T is the natural rolling period (6 seconds), L is the length of the vessel (114 feet), and B is the beam of the vessel (16 feet). Plugging in the values, we get GM = (6^2 * 114) / (0.0884 * 16) = 1.38 feet. The other options are incorrect because they do not match the result calculated using the formula.
