Your vessel displaces 585 tons and measures 128'L by 26'B. What is the reduction in GM due to free surface if the fish hold
AI Explanation
The correct answer is A.
The reduction in GM (metacentric height) due to free surface effect is calculated using the formula:
Reduction in GM = B^2 / (12 * D)
Where:
B = Beam of the vessel (in feet)
D = Displacement of the vessel (in tons)
Given information:
Vessel displacement = 585 tons
Vessel dimensions = 128'L x 26'B
Plugging in the values, we get:
Reduction in GM = 26^2 / (12 * 585) = 676 / 7,020 = 0.096 feet
Therefore, the correct answer is A.
The other options are incorrect because they do not correctly calculate the reduction in GM using the provided formula and vessel characteristics.
