Q

When the height of the metacenter is less than the height of the center of gravity, a vessel has which type of stability?

🔍 Key Concepts

• Relationship between metacenter (M) and center of gravity (G) • Definition of GM (metacentric height) and what happens when it is positive, zero, or negative • How the vessel reacts when heeled if G is above or below M

💭 Think About

• Visualize the vertical order of points: keel (K), center of buoyancy (B), center of gravity (G), and metacenter (M). What does it mean physically if G is higher than M? • Think about the sign of GM (M minus G). What kind of righting or upsetting moment is created when GM is positive, zero, or negative? • Ask yourself: in this situation, if the vessel is heeled a small angle, will it tend to return to upright, stay where it is, or continue to heel more?

✅ Before You Answer

• Be clear that GM = KG subtracted from KM (GM = KM − KG) and what a negative value represents • Distinguish between stability condition (positive/neutral/negative) and a general word like "stable" • Confirm which term is used when a small heel produces a capsizing (overturning) moment instead of a righting moment
