Your vessel displaces 475 tons. The existing deck cargo has a center of gravity of 2.6 feet above the deck and weighs 22 tons. If you load 16 tons of ground tackle with an estimated center of gravity of 8 inches above the deck, what is the final height of the CG of the deck cargo?

Question

Accepted Answer

Option D: 1.79 feet. Moments about the deck are computed using existing cargo (22 tons at 2.6 ft) and added ground tackle (16 tons at 0.67 ft). Dividing total vertical moments by total deck cargo weight (38 tons) results in a final CG of 1.79 feet.
