摘要

A keel guide device (3,4) fits on the lower boat wall (1a) and extends crossways to the boat longitudinal direction in a circular arc formation. The keel (2) is movably located in the guide device and can travel (5) along the boat underside and partly fitted inside the boat and partly outboard on the keel is a keel drive (10,11,12,7,8). The guide device comprises at least two parallel rails (3) with running tracks (4) which hold up the guide body (5) of the keel. The keel comprises a keel part (20) forming the keel body which is exchangeable and has a frame (6) curved dependent on the boat underside with guide bodies (5) running in the guide device. ADVANTAGE - Improves the stability, travel and glide properties of a sail boat.
