🔍 Key Concepts

• Free surface effect and how it reduces a vessel’s GM (metacentric height) • What a moment is (force × distance) and how we turn total moments into an average value • The difference between displacement, deadweight, and lightweight

💭 Think About

• When you have a total ‘free-surface moment’ in ton-meters or foot-tons, what do you divide by to get a change in GM that applies to the whole ship? • Which of the listed weights represents the entire vessel’s mass in the water at that condition (not just cargo or just liquids)? • Think about the standard formula used in stability books for free surface correction: what is in the numerator and what is in the denominator?

✅ Before You Answer

• Identify which option refers to the ship’s total mass afloat at that loading condition • Check which quantity would give a global effect on stability, not just on one part of the load • Verify from your stability formula sheet what is used to convert free-surface moment into a GM correction: numerator vs. denominator
