Keel
Keel the part of a boat that extends along the bottom from stem to stern, serving as a 'backbone' upon which the hull is built (sailing) (chambers. Sports factf.,2005, 504P.) Keel the structure of the bottom of the boat running along the centre from bow to stern (rowing) (chambers. Sports factf.,2005, 470P.) Keel on a boat the lower longitudinal bond running amidship. In a rowing boat the lowest longitudinal edge of the boat, which is located outside the boat in a gig, inside in a racing boat. In a sailboat the beam forming the lowest part of the boat. Such sailboats are called keel boats or yachts (in contrast to sailing dinghies which are equipped with a centerboard) and have a low-lying keel with an additional ballast keel added on at its bottom. Since the center of gravity of the boat is low, the drift is smaller, the sail carrying capacity greater, and the boat cannot capsize. In a keel-centerboard boat the ballast keel is higher than in a keel boat and a centerboard can be lowered which prevents a sideways drift. (H.Haag &g. Haag, dictionary, 2003, 271p.)
