Q

What does a slow and easy motion of a vessel in a waterway indicate?

🔍 Key Concepts

• Initial stability (GM) and how it affects rolling period • Difference between a stiff vessel and a tender vessel • Relationship between GM and the roll speed (quick vs slow motion)

💭 Think About

• Think about what happens to a vessel’s rolling motion when the metacentric height (GM) is large versus when it is small. • Ask yourself: does a vessel with a low GM roll quickly and sharply, or slowly and gently? • Which of the options directly describes or is closely related to a vessel that has a slow, easy rolling period?

✅ Before You Answer

• Identify which choice is associated with a small GM and which with a large GM. • Recall that a stiff vessel has what kind of GM and what kind of roll motion (fast or slow)? • Connect the idea of slow and easy motion specifically to the vessel’s stability characteristics, not just one geometric point like GZ at a single angle.
