🔍 Key Concepts

• Transverse stability (side-to-side stability) • Effect of center of gravity (G) moving higher or lower in the vessel • Difference between a stiff vessel and a tender vessel in rolling behavior

💭 Think About

• Think about what happens to a ship’s rolling motion when most of the weight is high up: does it roll quickly and snappily, or slowly and gently? • Which term describes a vessel that has a small initial stability, causing slow, easy rolls? • How does raising the center of gravity affect the metacentric height (GM): does it become large or small, and which term matches that condition?

✅ Before You Answer

• Identify which term (stiff or tender) is associated with large GM and quick, jerky rolls. • Identify which term is associated with small GM and slow, lazy rolls. • Confirm that buoyant and neutral do NOT specifically describe the rolling behavior caused by weight high in the vessel.
