- Q131 - Deck Safety: Stability Problems
203. Your vessel displaces 968 tons and measures 158'L x 40'B. You ship a large wave on the after deck. What is the reduction to GM due to free surface before the water drains overboard, if the after deck measures 65'L x 40'B and the weight of the water is 80 tons?
The reduction in GM due to free surface is calculated using the free surface moment of inertia divided by the total displacement (ship plus shipped water), which is 1048 tons. The moment of inertia is determined by the length and breadth of the after deck (65'L x 40'B), resulting in a GM reduction of 9.45 feet.
