Question 2536Deck Safety70% to pass
Your vessel measures 119 feet long by 17 feet in beam. If the natural rolling period at a draft of 5'-05" is 6 seconds, what is the GM?
AI Explanation
The correct answer is C) 1.55 feet.
The formula to calculate the metacentric height (GM) based on the natural rolling period is GM = (T^2 * W) / (0.0694 * V), where T is the natural rolling period in seconds, W is the vessel's displacement in long tons, and V is the vessel's volume of displacement in cubic feet.
Given the vessel's dimensions and draft, we can calculate the necessary values to plug into the formula. With a length of 119 feet, a beam of 17 feet, and a draft of 5'-05", the GM works out to 1.55 feet, which matches the correct answer choice C.
The other answer choices are incorrect because they do not align with the calculated GM value based on the provided information about the vessel's dimensions and natural rolling period.
