Your vessel displaces 641 tons. The existing deck cargo has a center of gravity of 3.6 feet above the deck and weighs 36 tons. If you load 22 tons of ground tackle with an estimated center of gravity of 2.0 feet above the deck, what is the final height of the CG of the deck cargo?

🔍 Key Concepts

• Weighted average for centers of gravity when combining two loads • Using the moment = weight × distance idea for vertical CG problems • Remembering that you only use the weights on deck, not the whole vessel displacement, to find the deck cargo CG

💭 Think About

• How do you combine two different cargo items with different centers of gravity into one overall center of gravity? Think about total moment divided by total weight. • What is the moment of the existing 36-ton deck cargo about the deck, and what is the moment of the 22-ton ground tackle? • Once you add the two weights together, how do you use the sum of the moments to find the new combined center of gravity height?

✅ Before You Answer

• Be sure you are only using the 36 tons and 22 tons when calculating the deck cargo CG, not the vessel’s 641-ton displacement. • Carefully compute each individual moment = weight × height before adding them together. • After finding the combined CG height, compare your value to the choices and check that it is between 2.0 ft and 3.6 ft, since it must lie between the two original CG heights.
