- Q131 - Deck Safety: Stability Problems
175. A vessel carries three slack tanks of gasoline (SG .68). The vessel's displacement is 8,000 tons. Each tank is 50 ft. long and 20 ft. wide. What is the reduction in GM due to free surface with the vessel floating in sea water (SG 1.026)?
The reduction in GM due to free surface is calculated using the formula considering the liquid's specific gravity, the tanks' dimensions, and the ship's displacement volume, resulting in a loss of .24 feet.
