| 释义 | keel (once / 1069 pages) 1n 2v The keel of a boat is the beam that runs the length of the hull — the body of the boat — and can extend vertically into the water to provide stability. A keel doesn't just refer to the stabilization of boats. When you're on "an even keel," you're stable and steady. On a bird, the keel (or breastbone) enables a bird to fly. On the other hand, if you keel over, you're quite the opposite, since you've just gone crashing to the floor.
