Question 2632 Deck Safety

The correct answer is D) 3.6 feet. To determine the righting arm at 45° inclination, you need to use the selected stability curves in the blue pages of the Stability Data Reference Book, given the vessel's drafts and KG. Based on the information provided, the righting arm at 45° inclination is 3.6 feet, as indicated in the stability curves. The other options are incorrect because they do not match the value shown in the stability curves for the given vessel characteristics. The righting arm at 45° inclination is a specific value that can be determined from the stability data, and 3.6 feet is the correct answer based on the information provided.
