Your vessel's drafts are: FWD 17'-07", AFT 16'-09"; and the KG is 24.8 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 15° inclination.

Correct Answer: Option A — 0.7 foot

Calculate the mean draft and use the KG of 24.8 feet to reference the stability curves. At 15 degrees, the righting arm is extracted. This process ensures the mariner can accurately assess the vessel's righting moment, which is vital for maintaining safe stability and preventing capsizing under external forces.
