🔍 Key Concepts

• List vs. trim – understand the difference between a vessel leaning to one side and being down by the bow or stern • Transverse stability – how weight moved sideways (port/starboard) affects list • Effect of shifting liquids (like fuel) on a vessel’s center of gravity

💭 Think About

• If the vessel is listing to starboard, which side is lower in the water? How could moving weight change that? • Does moving fuel forward or aft correct a side-to-side tilt, or mainly affect bow-stern trim? • When you move fuel from one tank to another, what happens to the vessel’s center of gravity in the transverse (side-to-side) direction?

✅ Before You Answer

• Identify clearly which way the vessel is leaning when you have a starboard list • Decide whether you need to correct a side-to-side problem or a bow-stern problem • Confirm which tank transfer will move the vessel’s center of gravity toward the higher side to level the vessel
