Question 2529 Deck Safety
70% to passYour 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?
A
0.8 ft
B
1.1 ft
C
1.4 ft
D
1.6 ft
AI Explanation
The correct answer is B) 1.1 ft. The formula to calculate the metacentric height (GM) of a vessel is: GM = B^2 / (12 * T) Where: B = Beam of the vessel (in feet) T = Rolling period of the vessel (in seconds) Given: Beam (B) = 60 feet Rolling period (T) = 25 seconds Plugging these values into the formula: GM = 60^2 / (12 * 25) GM = 3600 / 300 GM = 1.1 feet The other options are incorrect because they do not match the result obtained from the formula. Option A (0.8 ft) is too low, while options C (1.4 ft) and D (1.6 ft) are too high.
