Your vessel displaces 684 tons and measures 132'L by 31'B. What is the reduction in GM due to free surface if the fish hold
AI Explanation
The correct answer is C.
To calculate the reduction in GM (metacentric height) due to free surface, we need to use the formula: Reduction in GM = I / (W * GM). Where I is the moment of inertia of the free surface, W is the weight of the liquid, and GM is the initial metacentric height.
Given:
Vessel displacement = 684 tons
Vessel dimensions = 132'L x 31'B
The key information here is the presence of a fish hold, which indicates that there is a free surface effect. The reduction in GM due to this free surface would be the correct answer.
The other options do not provide enough information to calculate the reduction in GM, as they do not mention the presence of a free surface.
