Your sailing drafts are: FWD 21'-08", AFT 22'-04" and the GM is 3.2 feet. What will be the angle of list if the #6 port deep tank (capacity 201 tons, VCG 11.4 feet, and 25.5 feet off the centerline) is filled? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)
Official USCG Answer & Rule Citation
Correct Answer: Option D — 8°
Adding 201 tons of saltwater to #6 port deep tank at 25.5 feet off centerline creates a significant heeling moment. Factoring ship displacement and a GM of 3.2 feet via stability data yields a calculated transverse list angle of 8 degrees.
