Your sailing drafts are: FWD 22'-04", AFT 23'-06" and the GM is 3.2 feet. What will be the angle of list if #3 starboard double bottom (capacity 97 tons, VCG 2.5 feet and 23 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 B — 3°

Calculating list induced by ballasting an off-center double bottom tank requires determining the transverse heeling moment ($w \times d$). Dividing this moment by the vessel's displacement and metacentric height (GM of 3.2 feet) using blue page hydrostatic data results in a list angle of 3 degrees.
