The SS AMERICAN MARINER has on board 7240 tons of cargo with an LCG-FP of 273.20 feet. See table ST-0165 below for the distribution of the cargo to be loaded. Use the white pages of The Stability Data Reference Book to determine the final LCG-FP of the cargo.

🔍 Key Concepts

• Use the white pages LCG-FP values for each cargo location on SS AMERICAN MARINER (No. 1 MD, No. 2 TD, No. 3 SD, etc.) • Compute longitudinal moments for both the existing cargo and the added cargo: Moment = Weight × LCG-FP • Find the resultant LCG-FP of all cargo: New LCG-FP = (Sum of all cargo moments) ÷ (Total cargo weight)

💭 Think About

• What is the total moment of the cargo already on board (7240 tons at LCG-FP 273.20 ft), and how do you compute it? • After you look up each compartment’s LCG-FP in the white pages, how will you combine the moments of the added cargo with the existing cargo moment? • Once you have the new overall LCG-FP, is it forward or aft of the original 273.20 ft, and which choice best matches that shift?

✅ Before You Answer

• Be sure you are using the correct LCG-FP for each exact stowage position (deck and tank top matter). • Verify that your total added cargo weight from the table matches the sum of all listed weights before using it in your final calculation. • Double-check that you divide total moment by total weight (not the other way around) when finding the final LCG-FP.
