How to choose this product
A traditional keel is a structural element running the length of the craft. It constitutes the backbone of the vessel to which the frames are attached. In modern sailboats, the keel is a longitudinal structure hanging vertically below the vessel's hull to resist drift. The different keels offered on NauticExpo include retractable, swing and pivoting models.
The keel of modern boats has two functions. It counters drift and serves as ballast, acting as a counterweight to limit heeling and avoid capsize.
The keel is a flat, elongated piece, sometimes with a bulbous counterweight. The keel may be fixed or equipped with a variety of mechanisms to adjust its position. Retractable keels allow for the reduction of keel surface. Swing or cant keels can swing from side to side to alter the center of resistance. Pivoting keels can be swung up or down along the centerline to change the center of resistance.
How to choose
Vessel type, dimensions and displacement will determine choice of keel. Fixed, retractable and swing models should be considered.
