Your vessel's drafts are: FWD 22'-04", AFT 22'-10"; and the KG is 18.4 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 30° inclination.

Correct Answer: Option D — 4.6 feet

Determine the mean draft and use the KG of 18.4 feet to select the correct stability curve. At 30 degrees, the righting arm is read from the blue pages. This ensures the vessel's stability is correctly evaluated, maintaining compliance with safety standards for vessel operation and cargo loading conditions.
