Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 60° inclination.

Correct Answer: Option B — 1.8 feet

Using the Stability Data Reference Book, determine the mean draft (27' 10") and the vessel's KG. Locate the corresponding stability curve for the calculated displacement. By plotting the 60-degree inclination on the cross-curves of stability, the righting arm (GZ) is identified as 1.8 feet for this specific loading condition.
