Question 2525 Deck Safety
70% to passYour vessel has a metacentric height of 1.12 feet and a beam of 60 feet. What will your average rolling period be?
The correct answer is C) 25 seconds. The formula to calculate the average rolling period (T) of a vessel is: T = 2π * √(GM/g) Where: - T is the average rolling period in seconds - GM is the metacentric height in feet - g is the acceleration due to gravity, which is approximately 32.2 ft/s² Given: - Metacentric height (GM) = 1.12 feet - Beam = 60 feet Plugging these values into the formula: T = 2π * √(1.12/32.2) T = 25 seconds The other options are incorrect because: A) 23 seconds is too low for the given metacentric height and beam. B) 35 seconds is too high for the given metacentric height and beam. D) 20 seconds is too low for the given metacentric height and beam.
