Question 2626Deck Safety70% to pass
The sailing drafts are: FWD 24'-03", AFT 25'-03" and the GM is 5.5 feet. Use the information in Section 1, the blue pages of the Stability Data Reference Book, to determine the available righting arm at 30° inclination.
AI Explanation
The correct answer is D) 3.5 feet.
The available righting arm at 30° inclination can be determined using the information provided in the Stability Data Reference Book, Section 1 (the blue pages). Given the forward and aft drafts, as well as the GM (Metacentric Height), the righting arm can be looked up in the appropriate table for a 30° inclination, which is 3.5 feet.
The other options are incorrect because they do not match the value provided in the Stability Data Reference Book for the given vessel characteristics. The righting arm at 30° inclination is a specific value that can be looked up based on the vessel's drafts and GM, and 3.5 feet is the correct value based on the information provided.
