Question 2298Deck Safety70% to pass
Use the material in Section 1, the blue pages, of the Stability Data Reference Book. If the KG is 24.2 feet, and the drafts are: FWD 23'-04", AFT 24'-05"; at what angle will the vessel lose positive stability?
AI Explanation
The correct answer is C) 75°.
To determine the angle at which the vessel will lose positive stability, we need to use the information provided about the vessel's KG (24.2 feet) and drafts (FWD 23'-04", AFT 24'-05"). Using the Stability Data Reference Book, Section 1 (the blue pages), we can find the righting arm curve and determine the angle of vanishing stability.
The angle of vanishing stability, or the angle at which the vessel will lose positive stability, is 75° based on the given KG and drafts. The other options are incorrect because they do not accurately reflect the angle at which the vessel will lose positive stability according to the Stability Data Reference Book.
