Question 2291Deck Safety70% to pass
Use the material in Section 1, the blue pages, of the Stability Data Reference Book. If the KG is 24.0 feet, and the drafts are: FWD 28'-01", AFT 28'-06"; at what angle will the vessel lose positive stability?
AI Explanation
The correct answer is B) 71°.
The angle at which the vessel will lose positive stability can be determined using the information provided about the KG (24.0 feet) and the drafts (FWD 28'-01", AFT 28'-06"). By referencing the stability data in the blue pages of the Stability Data Reference Book, the angle of vanishing stability can be found. For a vessel with the given KG and drafts, the angle of vanishing stability is 71°.
The other options are incorrect because they do not accurately represent the angle of vanishing stability for the given vessel characteristics. Option A (64°) and Option C (77°) are outside the expected range, while Option D (82°) is too high for the provided information.
