The correction to KG for longitudinal free surface effects for a vessel can be found by dividing the vessel's displacement into the __________.

🔍 Key Concepts

• Free surface effect (FSE) and how it affects vessel stability • Difference between moment (force × distance) and correction to KG (a length) • How longitudinal and transverse free surface corrections are calculated conceptually

💭 Think About

• Ask yourself: to turn a free surface effect into a correction to KG, do you need something that has units of moment or something that is just a distance? • Which quantity, when divided by the vessel's displacement, will give you a value with units of length (meters or feet) that can be applied as a correction to KG? • Among the choices, which option clearly represents a sum of moments associated with free surfaces in the longitudinal direction?

✅ Before You Answer

• Verify which choice refers specifically to longitudinal free surface moments, not transverse effects or centerlines • Check the units: displacement usually has units of weight (tons, long tons, etc.); what must the numerator’s units be so that the result is a distance? • Confirm that the correct numerator must describe a total moment due to free surfaces, not a geometric feature like a centerline or generic vertical moments
