Question 2297Deck Safety70% to pass
Use the material in Section 1, the blue pages, of the Stability Data Reference Book. If the KG is 23.0 feet, and the drafts are: FWD 15'-03", AFT 15'-09"; at what angle will the vessel lose positive stability?
AI Explanation
The correct answer is D) 90°.
This is because when the KG (center of gravity) is 23.0 feet, and the vessel has a forward draft of 15'-03" and an aft draft of 15'-09", the vessel will lose positive stability at an angle of 90°. At this angle, the vessel will have reached its maximum righting arm, and any further increase in the angle of inclination will result in the vessel losing positive stability.
The other answer choices are incorrect because they do not represent the angle at which the vessel will lose positive stability given the provided draft and KG values.
