Your vessel displaces 930 tons and measures 156'L by 38'B. What is the reduction in GM due to free surface if the fish hold (46'L by 28'B by 8'D) is filled with 1.5 feet of water? (Each foot of water weighs 36.8 tons)

Correct Answer: Option B — 2.44 feet

Liquid in partially filled compartments creates a free surface effect that diminishes vessel stability. Applying the standard transverse inertia formula to these specific dimensions and 930 tons displacement produces a 2.44-foot reduction in GM.
