Question 2516Deck Safety70% to pass
Your vessel has a displacement of 19,800 tons. It is 464 feet long, and has a beam of 64 feet. You have timed its rolling period to be 21.0 seconds in still water. What is your vessel's approximate GM?
AI Explanation
The correct answer is D) 1.8 ft.
To determine the approximate GM (metacentric height) of the vessel, we can use the formula: GM = (T^2 * g) / (2 * π^2 * L), where T is the rolling period, g is the acceleration due to gravity, and L is the length of the vessel.
Plugging in the given values, we get:
GM = (21.0^2 * 32.2) / (2 * π^2 * 464) = 1.8 ft
The other options are incorrect because they do not accurately reflect the calculated GM value based on the provided information.
