🔍 Key Concepts

• Use the white pages of the Stability Data Reference Book for the SS AMERICAN MARINER (one‑compartment standard tables). • Understand how liquid loading in double bottom tanks affects GM and the minimum stability criteria after flooding one compartment. • Carefully total the given cargo weights (deck, upper tween, lower tween, hold) and match them to the correct displacement/GM entry in the tables.

💭 Think About

• First, add up all the cargo layers in the illustration. How does this total cargo weight relate to the ship’s displacement in the one‑compartment standard tables? • Once you find the displacement that matches this loading condition, what table entry tells you the required liquid loading in the double bottoms? • If your displacement falls between two tabulated values, how should you handle that when reading required double‑bottom loading (interpolation or using the nearest value)?

✅ Before You Answer

• Be sure you are in the correct ship and correct condition: SS AMERICAN MARINER, one‑compartment standard, not intact stability. • Verify the total cargo weight from the illustration matches the displacement row (plus lightship and any constant) you’re using in the table. • Confirm the value you pick is labeled as required liquid loading in double bottom tanks, not GM, not maximum KG, and not allowable deck cargo.
