Question 1 of 27070

Stability is determined principally by the location of two points in a vessel. These points are the center of buoyancy and the __________.

🔍 Key Concepts

• center of buoyancy (B) is the center of the underwater volume of the vessel • center of gravity (G) is where the vessel’s total weight is considered to act • Initial stability and metacentric height (GM) depend on the relationship between B and G

💭 Think About

• Which point represents the ship’s WEIGHT, not the water it displaces? • When a ship heels, which two points shift relative to each other to create a righting or capsizing moment? • Think of the classic stability diagram: which two labeled points are always shown when discussing GM (metacentric height)?

✅ Before You Answer

• Verify which option describes where the ship’s weight acts vertically. • Eliminate any point that refers only to the water surface or waterplane, not the whole ship. • Ask: in basic stability curves and righting arm (GZ) diagrams, which point is always paired with the center of buoyancy?
