🔍 Key Concepts

• Center of gravity (G) and how moving weight affects it • Relationship between center of gravity and metacentric height (GM) for stability • Difference between stability, trim, and list

💭 Think About

• When you move weight from a higher deck to a lower deck, what happens to the ship’s overall center of gravity? Up, down, forward, or aft? • How does a lower or higher center of gravity affect a vessel’s tendency to return to upright after being heeled? Stronger or weaker? • Which options describe permanent fore‑and‑aft change, side‑to‑side tilt, or overall resistance to heeling?

✅ Before You Answer

• Be clear on the definition of stability (ability to return to upright after heeling). • Distinguish trim (bow vs stern) from list (port vs starboard). • Ask: Does the question say anything about moving weight forward/aft or side-to-side, or only higher vs lower? This will help eliminate some choices.
