🔍 Key Concepts

• Center of gravity (G) vs center of buoyancy (B) and how they move when a vessel heels • Difference between righting arm (GZ), righting moment, and metacentric height (GM) • What "line of force" means in the context of weight vs buoyant force on a heeled vessel

💭 Think About

• When a vessel heels and still has positive stability, what force acts through G and what force acts through B? Visualize these as vertical lines on a cross-section. • Ask yourself: which term describes a distance between two vertical lines of action of forces, and which terms describe either a distance to M or a turning effect (moment)? • Consider a typical stability diagram: where is G, where is B, where is M, and what is the name of the horizontal distance that creates the tendency to right the ship?

✅ Before You Answer

• Verify which choice specifically refers to the horizontal distance between the verticals through B and G when the ship is heeled. • Check which terms are distances (measured in meters/feet) versus which are moments (force × distance). • Confirm which term is drawn on a GZ (stability) curve as the lever arm responsible for the righting moment.
