shoal keel sailboats

Shoal keel sailboats are boats with less draft compared to the same model with a higher keel. The term shoal keel does not define a certain length of the keel rather than just differentiate one model from another. By reading the term shoal keel on a boat, you are meant to understand that a version with a normal keel is also available and that the particular model you are looking at can be used in shallower waters than the other one.
