The liquid mud tanks on your vessel measure 22'L by 16'B by 7'D. The vessel's displacement is 568 T and the specific gravity of the mud is 1.6. What is the reduction in GM due to a pair of these tanks (p/s) being slack?

AI Explanation
The correct answer is C) 1.18 feet. To explain: 1. The reduction in GM (metacentric height) due to a pair of slack liquid mud tanks on the vessel is 1.18 feet. 2. This can be calculated using the formula for the change in GM due to free surface effect, which is (I/Δ) * (ρ/Δ), where I is the moment of inertia of the free surface, Δ is the vessel's displacement, and ρ is the density of the liquid. 3. The other options are incorrect because they do not accurately reflect the reduction in GM based on the given tank dimensions, displacement, and specific gravity of the mud. 4. The calculation shows that the correct answer is 1.18 feet.
