When a vessel is floating upright, which term is used to define the distance from the keel to the metacenter of a vessel?

🔍 Key Concepts

• Keel – the lowest structural part of the ship from which vertical measurements are often taken • Metacenter (M) – the point about which a small-angled heeling vessel oscillates • Difference between metacentric radius and metacentric height

💭 Think About

• Ask yourself: from which reference point is this distance being measured—keel, center of gravity (G), or center of buoyancy (B)? • Which term specifically uses the word 'radius' in relation to B and M, and which uses 'height' in relation to K and M or G and M? • Think about which quantity naval architects use as a direct vertical measure from the keel up to the metacenter.

✅ Before You Answer

• Verify which option describes a distance measured from the keel to M (the metacenter) • Eliminate any term that normally involves G (center of gravity) instead of the keel • Eliminate any option that refers to a moment arm when the vessel is heeled, rather than a basic vertical stability dimension
