Question 2630Deck Safety70% to pass
The sailing drafts are: FWD 23'-10", AFT 25'-02" and the GM is 5.3 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 18° inclination.
AI Explanation
The correct answer is D) 1.9 feet.
To determine the available righting arm at 18° inclination, we need to use 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), we can use the stability curves to find the righting arm at 18° inclination. The stability curves provide the righting arm values for different GM and draft combinations at various angles of inclination. In this case, the righting arm at 18° inclination for the given drafts and GM is 1.9 feet, making option D the correct answer.
The other options are incorrect because they do not match the value obtained from the Stability Data Reference Book for the provided vessel characteristics.
