- Q122 - Deck Safety: Stability Problems
187. Your vessel displaces 750 tons and measures 151'L by 35'B. What is the reduction in GM due to free surface if the fish hold (60'L by 31'B by 10'D) is filled with 3.5 feet of water? (Each foot of water weighs 53.1 tons)
The reduction in GM due to free surface is calculated by dividing the free-surface moment by the total displacement, including the weight of the added water. Using the given dimensions and water weight, the GM reduction is approximately 4.55 feet.
