Question 2531 Deck Safety

The correct answer is C) 1.7 ft. The metacentric height (GM) of a vessel can be estimated using the formula: GM = B^2 / (2 * T * P^2), where B is the beam of the vessel, T is the full period of roll, and P is the acceleration due to gravity (typically 32.2 ft/s^2). Plugging in the given values, we get: GM = (60 ft)^2 / (2 * 20 s * 32.2 ft/s^2) = 1.7 ft. The other options are incorrect because they do not match the result of the calculation using the provided formula and vessel dimensions.
