The HEOL 7.4, design by Martin Defline is a current example of the ocean-going evolution of the racing dingy that uses twin keels; it is similar in size and characteristics to the Classe Mini. The twin keels are lifting; the windward (or upwind), keel (or fin), hinges aft (or backwards) and lays against the side of the hull.
