Your sailing drafts are: FWD 17'-07", AFT 18'-05" and the GM is 3.4 feet. What will be the angle of list if #4 port double bottom (capacity 140 tons, VCG 2.6 feet, and 26 feet off the centerline) is filled with saltwater? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)

Correct Answer: Option C — 6°

Transverse list calculations use the standard formula: $\tan(\text{List}) = \frac{w \times d}{\Delta \times \text{GM}}$. Filling #4 port double bottom introduces off-center mass, creating a transverse moment. Using blue page vessel particulars and a GM of 3.4 feet calculates a resulting list of 6 degrees.
