🔍 Key Concepts

• initial stability (GM) and what makes it larger or smaller • Effect of free surface in tanks on stability • How adding or removing weight at different vertical positions changes the center of gravity (G)

💭 Think About

• For each option, ask: does this change the free surface effect, or the vertical position of the center of gravity (G), or both? • Which actions tend to raise G (reducing stability) and which tend to lower G (improving stability)? • Think about what happens when a tank is partly filled versus pressed full or kept empty — how does that affect the vessel’s ability to return upright after heeling?

✅ Before You Answer

• For each choice, decide whether it would reduce free surface effect or lower the center of gravity. Those are the only ways it can improve initial stability. • Check whether closing crossover valves in partly filled double bottoms changes how the liquid moves from side to side. • Consider if removing loose water from decks or spaces changes free surface or weight location in a way that would increase GM.
