- Q104 - Deck Safety: Stability Problems
126. What is the reduction in metacentric height due to free surface when a tank 60 feet long and 30 feet wide is partially filled with salt water, and is fitted with a centerline bulkhead? (The vessel has a displacement of 10,000 tons.)
A centerline bulkhead reduces the free-surface moment to one-quarter of an unsplit tank, resulting in a 0.1-foot reduction in metacentric height.
