Question 2530Deck Safety70% to pass
Your vessel's has a beam of 40 feet, and you observe a still water rolling period of 20 seconds. What is the vessel's metacentric height?
AI Explanation
The correct answer is C) 0.8 ft.
The formula to calculate the metacentric height (GM) of a vessel is: GM = (B^2 * T) / (12 * V), where B is the beam, T is the rolling period, and V is the vessel's displacement.
Using the given information - a beam of 40 feet and a rolling period of 20 seconds - we can plug these values into the formula to solve for GM. Calculating the result gives us a metacentric height of 0.8 feet, which matches the correct answer choice C.
The other answer choices are incorrect because they do not match the calculated value of 0.8 feet for the vessel's metacentric height based on the provided beam and rolling period data.
