Question 4713 Deck General

The correct answer is C) loll. A semisubmersible with a negative GM (Metacentric Height) will experience a loll, which is a slow and unstable rolling motion to a significant angle of inclination. This is because a negative GM indicates the vessel's center of gravity is above the metacenter, making the vessel inherently unstable and prone to large rolling motions. The other answer choices are incorrect because heel refers to a sudden tipping to one side, list is a sustained inclination to one side, and trim is the difference in draft between the bow and stern, which is not the appropriate term for the scenario described.
