Question 2636Deck 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 30° inclination.
AI Explanation
The correct answer is B) 2.1 feet.
To determine the righting arm at 30° inclination, you need to use the stability curves provided in the blue pages of the Stability Data Reference Book. Given the vessel's drafts (FWD 18'-09" and AFT 20'-05") and the KG of 23.8 feet, you can locate the appropriate stability curve and read the righting arm value at 30° inclination, which is 2.1 feet.
The other options are incorrect because they do not match the righting arm value obtained from the stability curves for the provided vessel characteristics.
