🔍 Key Concepts

• Use the white pages of the SS AMERICAN MARINER Stability Data Reference Book to find the KG for each hold and deck location listed in table ST-0022 (e.g., No. 1 Main Deck, No. 2 Tank Top, etc.). • Remember the combined KG formula: final KG is total vertical moment divided by total weight of ship plus loaded cargo. • Include the existing cargo already onboard (2685 tons at KG 27.4 ft) when you sum weights and moments.

💭 Think About

• Are most of the new cargo weights being placed above or below the ship’s current KG of 27.4 ft, and should that make the final KG go up or down? • Once you’ve looked up each stowage location’s KG in the white pages, have you multiplied each cargo weight by its location KG and then added those moments to the existing cargo moment? • After finding the total weight and total moment, which of the answer choices is closest to the calculated final KG, and does its direction of change (up or down from 27.4 ft) make physical sense?

✅ Before You Answer

• Be sure every line in the illustration (all holds and decks: No. 1 through No. 7) is accounted for in your weight and moment totals. • Double‑check the existing cargo moment: (\text{Moment} = 2685,\text{tons} \times 27.4,\text{ft}). • Confirm your final KG is between the lowest and highest KG values of the cargo locations you used, and that it is less than 27.4 ft if most cargo is placed low in the ship.
