The SS AMERICAN MARINER has on board 4850 tons of cargo with an LCG-FP of 275.72 feet. See table ST-0107 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 the Stability Data Reference Book white pages for SS AMERICAN MARINER to find longitudinal positions (LCG from forward perpendicular) for each hold/deck listed • Applying the moment = weight × distance idea to find combined LCG of multiple cargo parcels • Using the formula for combined LCG: (Σ w·LCG) / Σ w and comparing with the ship’s existing cargo LCG of 275.72 ft

💭 Think About

• For each line in table ST-0107 (e.g., "No. 1 Third Deck 150"), what two numbers do you need from the Stability Data Book, and how do you turn them into a longitudinal moment? • After you add all the new cargo moments and weights to what is already on board (4850 tons at 275.72 ft), how do you compute the new overall LCG-FP? • Once you get a single final LCG value, which answer choice is closest, and does it make sense physically (did the cargo you added move the LCG forward or aft)?

✅ Before You Answer

• From the white pages, be sure you are using the correct longitudinal position (LCG-FP) for the exact space and deck named (e.g., No. 3 Third Deck vs No. 3 Tank Top). • Verify that you include both the existing cargo on board (4850 tons) and all new cargo weights from ST-0107 when summing weights and moments. • Double‑check that you divide total longitudinal moment by total weight to get the final LCG-FP, and that you keep all distances in feet from the forward perpendicular.
