1536. Your ship of 12,000 tons displacement has a center of gravity of 21.5 feet above the keel. You run aground and estimate the weight aground is 2500 tons. What would be the virtual rise in the center of gravity?

The virtual rise in the center of gravity is calculated as GG1 = (R x KG) / (Δ − R), resulting in a value of 5.66 feet, where R is the ground reaction, KG is the original height of G above the keel, and Δ is the original displacement.
