Question 4938Deck General70% to pass
A slow and easy motion of a MODU in a seaway is an indication of a _______________.
AI Explanation
The correct answer is A) small GM.
A small GM (metacentric height) indicates a vessel that is less stable and has a slow, easy motion in a seaway. This is because a small GM means the vessel's center of gravity is close to the metacenter, resulting in a low righting arm (GZ) and reduced stability. A vessel with a small GM will have a sluggish, lethargic motion as it rolls and pitches in the waves.
The other answer choices are incorrect because: B) a stiff vessel would have a large GM and a quick, jerky motion; C) a large GZ indicates a highly stable vessel, not a slow, easy motion; and D) a low center of gravity does not necessarily imply a small GM or slow, easy motion.
