The SS AMERICAN MARINER has on board 5480 tons of cargo with an LCG-FP of 274.46 feet. See table ST-0191 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

• Using LCG (Longitudinal Center of Gravity) measured from the Forward Perpendicular (FP) • Calculating total longitudinal moment as weight × LCG for each cargo group • Combining existing cargo with new cargo distribution from table ST-0191 to find the new overall LCG

💭 Think About

• How do you use the LCGs from the Stability Data Reference Book for each compartment (No. 1 Third Deck, No. 2 Second Deck, etc.) together with their weights in tons? • Once you find the longitudinal moment for each new load, how do you combine those moments with the moment of the cargo already on board (5480 tons at LCG-FP 274.46 ft)? • After summing all weights and all moments, what single formula gives you the final combined LCG-FP of the cargo?

✅ Before You Answer

• From the white pages, verify the correct LCG-FP for each named space (e.g., No. 4 Tank Top, No. 5 Third Deck REEFER, etc.). • Check that you use the same reference point (FP) for all LCG values and that all distances are in feet and weights in tons. • Before choosing an answer, confirm that your computed LCG-FP is reasonable compared to 274.46 ft (ask: does adding this distribution of cargo shift the LCG forward or aft, and by about how much?).
