🔍 Key Concepts

• inclined vessel stability and how the center of gravity (G) moves relative to the hull • relationship between center of gravity (G), center of buoyancy (B), and metacenter (M) when a vessel is heeled with NO external forces • what line or point the center of gravity must lie on for the vessel to be in equilibrium when inclined

💭 Think About

• When a vessel is heeled over but in stable equilibrium, what line passes through the center of buoyancy and metacenter? Where must the center of gravity sit relative to that line? • Which of the options represents a vertical reference that a point (like G) can be ‘aligned’ with, rather than just a fore‑and‑aft reference? • Think about which choice is directly tied to transverse stability and heel, rather than to trim (bow‑to‑stern attitude) or the waterplane shape alone.

✅ Before You Answer

• Identify which option is directly involved in transverse stability and heeling (not trim). • Ask yourself: when the vessel inclines, about which point or line does the buoyancy shift to create a righting or overturning moment? • Eliminate any choices that are only related to longitudinal references (fore‑and‑aft) or to the waterplane area rather than to heeling equilibrium.
