Question 2534Deck Safety70% to pass
Your vessel measures 125 feet long by 17 feet in beam. If the natural rolling period at a draft of 7'-09" is 6 seconds, what is the GM?
AI Explanation
The correct answer is C) 1.55 feet.
To calculate the GM (metacentric height), we can use the formula: GM = (T^2 * g) / (2 * pi^2 * L), where T is the natural rolling period (6 seconds), g is the acceleration due to gravity (32.2 ft/s^2), and L is the length of the vessel (125 feet).
Plugging in the values, we get: GM = (6^2 * 32.2) / (2 * pi^2 * 125) = 1.55 feet.
The other options are incorrect because they do not match the calculated value of 1.55 feet for the given vessel dimensions and natural rolling period.
