🔍 Key Concepts

• Use the initial drafts (FWD and AFT) to find the ship’s displacement and LCG/TCG in the white pages for SS AMERICAN MARINER • Locate the one-compartment standard / required GM curve or table that corresponds to the ship’s displacement (or draft condition) • Be careful to distinguish between existing GM (from hydrostatic data) and minimum required GM (from the damage-stability standard)

💭 Think About

• From the given drafts, what is the ship’s displacement according to the Stability Data Reference Book, and which page/curve applies to that loading condition? • On the one-compartment standard diagram, how do you read the required GM at that displacement or mean draft? Are you sure you’re not mixing it with KN or GZ data? • Once you read a GM value from the curve/table, does it need any interpolation between two points, and are the answer choices close enough that a small reading error would change which choice is correct?

✅ Before You Answer

• Confirm you are using the correct ship (SS AMERICAN MARINER) white pages and the correct draft condition (based on the FWD and AFT drafts given). • Verify whether the one-compartment standard is plotted against displacement, mean draft, or deadweight, and that you are matching the right axis before reading the GM. • Double-check that the value you pick off the curve is GM in feet, not meters or another stability parameter, and compare it carefully against the four choices.
