Q

A quick and rapid motion of a vessel in a seaway is an indication of a(n) __________.

🔍 Key Concepts

• Metacentric height (GM) and what a large GM does to a vessel’s motion • Relationship between stability stiffness and how “snappy” or “stiff” the roll feels • How center of gravity (G) height affects the speed versus slowness of rolling

💭 Think About

• Think about whether a vessel that feels very "stiff" and jerks quickly in roll has strong or weak initial stability • Ask yourself: does a high center of gravity make the vessel roll faster or more slowly and sluggishly? • Link the idea of quick, rapid motion with the size of the righting moment for small angles of heel

✅ Before You Answer

• Be clear on the definition of GM (metacentric height) and how a larger GM affects roll period • Review what a small GZ curve means for righting ability at small angles • Recall what excessive free surface normally does to GM and to the vessel’s tendency to be stiff or tender
