Deck General · Centers (G, B, M, K)
The center of buoyancy (B) is located at:
- AThe geometric center of the entire hull
- BThe centroid of the underwater volume of the vessel✓ Correct
- CThe point where the vertical through B intersects the vessel's centerline
- DThe midpoint between the keel and the waterline
Explanation
B is the centroid of the submerged volume. The buoyant force acts vertically upward through B. When the vessel heels, B shifts toward the low side as the shape of the submerged volume changes.
