Question 2108 Deck Safety

The correct answer is D) negative. At the angle of loll, the righting moment is negative. This means that the righting moment acts to increase the angle of loll, rather than to restore the vessel to an upright position. The angle of loll is the angle at which the center of gravity of a vessel is directly above the center of buoyancy, resulting in a negative righting moment. This condition is unstable, and the vessel will continue to capsize unless corrective action is taken. The other answer choices are incorrect because: A) the righting moment is not maximum at the angle of loll, B) the righting moment is not zero at the angle of loll, and C) the righting moment is negative, not positive, at the angle of loll.
