An original design, refined and ergonomic, dedicated to confort and performance. A L-shaped swivelling keel of 80 Kg (176 pounds) fully retractable guarantees an important righting couple and confers the inerty and confort in navigation of sports keel-sailboat. Carefully prepared fittings and sharpened sails set for pure sailing pleasure. A stable and swift boat for boating or racing. In rambling, lift and totally hidden in bottom, the keel permits to jump sandbanks or beach at any time on shore. Transport and launching can be done with same ease than a classical sailing dinghy.
