Question 2653Deck Safety70% to pass
Your vessel's drafts are: FWD 18'-09", AFT 20'-05"; and the KG is 23.8 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 26° inclination if the center of gravity is 1.0 foot off center.
AI Explanation
The correct answer is C) 0.8 foot.
To determine the righting arm at 26° inclination, we need to use the stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts (FWD 18'-09", AFT 20'-05") and the KG of 23.8 feet, we can locate the appropriate stability curve and read the righting arm at 26° inclination. Since the center of gravity is 1.0 foot off center, the righting arm will be shifted by this amount, resulting in a value of 0.8 foot.
The other options are incorrect because they do not accurately reflect the righting arm based on the provided information and the stability curves.
