🔍 Key Concepts

• Effect of lowering a weight on a ship’s center of gravity (G) • Relationship between center of gravity and metacentric height (GM) • How GM affects whether a vessel is stiff or tender, and its rolling period

💭 Think About

• When you move a weight downward inside the vessel, what happens to the ship’s overall center of gravity (does it go up or down)? • If the center of gravity moves that way, does GM become larger or smaller? How does that change the ship’s initial stability? • A vessel that returns very quickly and sharply from small angles of heel is called what? How does that relate to rolling period (long vs short)?

✅ Before You Answer

• Be clear on whether moving weight down increases or decreases GM • Connect large GM with stiff behavior and short rolling period, and small GM with tender behavior and long rolling period • Eliminate any choice that conflicts with the known effect of lowering G on stability and rolling
