Q

A negative metacentric height __________.

🔍 Key Concepts

• Metacentric height (GM) and what it indicates about a vessel's stability • Difference between positive GM, zero GM (neutral stability), and negative GM (unstable) • Typical causes of negative GM (e.g., free surface, very high center of gravity)

💭 Think About

• Think about what physically happens to a vessel when GM is negative—does it automatically capsize, or can other factors (like hull form or external restraints) temporarily prevent that? • Consider whether negative GM must always be fixed at once in every case, or whether it might be a calculated condition for a very short period (e.g., during loading) with controls in place. • Ask yourself: do off-center weights always have to be present for GM to become negative, or can GM be negative even when all weights are on centerline but too high?

✅ Before You Answer

• Be clear on the definition of GM: distance between center of gravity (G) and metacenter (M), and the sign (positive vs negative). • Verify whether negative GM = immediate capsize is always true under all real-world conditions. • Check if off-center weights are the only mechanism that can create negative GM, or if vertical weight distribution alone can do it.
