Q3. A 12 m long, 4.8 m wide, and 4.2 m deep rectangular pontoon has a draft of 2.8 m in seawater(specific gravity = 1.03). Assuming the load is uniformly

distributed on the bottom of the pontoon to a depth of 3.5 m, and the maximum design angle of list is 15°, determine the distance that the center of gravity can be moved from the center line toward the edge of the pontoon.
