🔍 Key Concepts

• Transverse stability and how it is measured by metacentric height (GM) • The meaning of free surface effect in slack tanks • How trim (by the bow or stern) differs from overall stability

💭 Think About

• Which option directly reduces a vessel’s ability to resist heeling, regardless of heading or trim? • Does changing trim by the bow or stern always make a ship less stable, or can it sometimes improve stability? • What happens inside a slack tank when the vessel heels—how does that affect the center of gravity and righting ability?

✅ Before You Answer

• Identify which choice involves liquid moving inside the vessel rather than just changing draft or trim • Ask whether the effect described acts whenever the ship heels, not just in one loading condition • Consider which option is usually treated as a hazard in stability textbooks and regulations, requiring calculation and correction
