Difference between keelhaul-keel and keel

Definitions

noun

1. the median ridge on the breastbone of birds that fly
2. one of the main longitudinal beams (or plates) of the hull of a vessel; can extend vertically into the water to provide lateral stability
3. a projection or ridge that suggests a keel

verb

1. walk as if unable to control one's movements

Examples

Ribs are straight or slightly biconcave and fade on the ventral surface where they merge into the lateral keel.

The single engine, semi-displacement hull form with deep forefoot and a long deep keel actually more closely resembles Down East-style workboats and cruisers.

The keel is a centreboard but not weighted; the ballast is in the hull itself (which sounds inefficient but actually works surprisingly well).
