Question 2112 Deck Safety

The correct answer is C) negative. The righting arm at an angle of loll (or heel) is negative. This is because at an angle of loll, the center of gravity is on the high side of the vessel, which creates a heeling moment that increases the angle of loll, rather than a righting moment that would decrease the angle. The negative righting arm indicates that the vessel is in a stable heel and will continue to heel further without intervention. The other options are incorrect because: A) the righting arm is not equal to the metacentric height (GM) at an angle of loll, B) the righting arm is not positive at an angle of loll, and D) the righting arm is not zero at an angle of loll, as it is a negative value.
