🔍 Key Concepts

• How the center of gravity (G) moves when weight is added high vs. low in the ship • Relationship between KG, KM, and GM (i.e., $GM = KM - KG$ ) • What happens to center of buoyancy (B) when draft increases slightly from added weight

💭 Think About

• If you add weight right at the keel (K), is that weight higher, lower, or at the same level as the current G, and therefore will G move up or down? • When G moves, how does that affect GM using the formula $GM = KM - KG$ ? Think about whether KG gets bigger or smaller. • Does simply adding weight at K directly push B up or down, or does B mainly depend on the underwater shape and draft?

✅ Before You Answer

• Be clear about which points are fixed to the hull (K, M) and which can move (G, B). • Verify whether adding weight low in the ship makes her more or less stable (i.e., does GM get larger or smaller?). • Confirm whether the option you choose matches both the motion of G and the expected change in stability (GM) when weight is added at the keel.
