🔍 Key Concepts

• Transverse metacentric height (GM) definition and when it applies • Difference between initial stability (small angles) and stability at large angles of heel • Behavior of the metacenter (M) as the ship heels over

💭 Think About

• Think about how the positions of G (center of gravity) and B (center of buoyancy) change as the ship heels: which one is fixed for a given loading condition, and which one moves? • Is the metacenter (M) a single, permanent point for all angles of heel, or is it only defined in a specific range of angles? • What does GM actually measure: stability at all angles, or just the ship’s tendency to return to upright from very small angles?

✅ Before You Answer

• Recall that GM is derived from the slope of the GZ curve near 0–10° of heel (initial stability only). • Verify which point, G or M, is considered constant for a given loading condition at small angles, and what happens to that point at large angles. • Confirm whether the definition of M (metacenter) remains valid at large angles of inclination or only for small angles.
