🔍 Key Concepts

• Longitudinal moments in stability/trim calculations • How the center of gravity (G) location is found using moments • Difference between a moment and the position of a point (like G)

💭 Think About

• When you add up all the individual weights times their distances forward/aft, what type of quantity is that? • If you then divide that total by the total vessel weight, what kind of value do you get: another moment, or a distance/location? • Which answer choice describes a position along the length of the vessel rather than a type of force or moment?

✅ Before You Answer

• Be clear on the definition of a moment = weight × distance • Ask yourself which options are types of moments versus a geometric location • Verify which choice specifically refers to a longitudinal location of G along the vessel’s length
