Question 2625Deck Safety70% to pass
The sailing drafts are: FWD 22'-08", AFT 23'-04" and the GM is 4.6 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 20° inclination.
AI Explanation
The correct answer is A) 2.1 feet.
The available righting arm at 20° inclination can be determined by looking up the righting arm (GZ) value in the Stability Data Reference Book, Section 1 (the blue pages), using the given sailing drafts and GM. With the forward draft of 22'-08", aft draft of 23'-04", and GM of 4.6 feet, the corresponding GZ value at 20° inclination is 2.1 feet.
The other answer choices are incorrect because they do not match the GZ value provided in the reference book for the given stability characteristics.
