🔍 Key Concepts

• Center of gravity (G) versus metacenter (M) and what their separation represents • Meaning of metacentric height (GM) and how it relates to stiffness or tenderness of a vessel or MODU • Difference between initial stability (small angles) and stability at large angles of heel

💭 Think About

• Ask yourself: GM is defined using the position of G and M at very small angles of heel. Does that relate more to initial behavior or to behavior at large angles? • Think about what part of the righting arm curve is influenced mainly by GM: is it the very beginning near zero heel, or the entire curve up to the maximum angle? • Consider how naval architects use GM in practice: when they say a vessel is "stiff" or "tender," are they talking about its behavior at small or large angles of heel?

✅ Before You Answer

• Be clear on the definition: GM = metacentric height = vertical distance between G and M • Recall that "initial" stability refers to stability at very small angles of heel (usually up to about 7–10°) • Check whether any option incorrectly suggests that GM alone describes stability over the full range of heel angles rather than only near upright.
