Question 2667Deck Safety70% to pass
Your vessel displaces 528 tons. The existing cargo has a center of gravity of 2.9 feet above the deck and weighs 28 tons. If you load 14 tons of ground tackle with an estimated center of gravity of 9 inches above the deck, what is the final height of the CG of the deck cargo?
AI Explanation
The correct answer is B) 2.18 feet.
The calculation to determine the final height of the center of gravity (CG) of the deck cargo is based on the principle of moment equilibrium. The new CG is calculated as the weighted average of the existing cargo CG and the new cargo CG, taking into account their respective weights.
Given:
- Vessel displacement: 528 tons
- Existing cargo weight: 28 tons, CG 2.9 feet above deck
- New cargo weight: 14 tons, CG 9 inches (0.75 feet) above deck
Using the formula for weighted average, the final CG of the deck cargo is calculated as 2.18 feet above the deck, which makes option B the correct answer.
The other options are incorrect because they do not accurately reflect the weighted average calculation for the final CG of the deck cargo.
