62. 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?

The reduction in GM due to two slack mud tanks is calculated by dividing the total free-surface moment of the tanks (density times transverse moment of inertia) by the vessel's displacement. Using the given tank dimensions, mud specific gravity, and vessel displacement, the calculation yields a reduction of 1.18 feet.
