Winged keel of Australia II. The Winged Keel is a sailboat keel originally designed by Ben Lexcen and made its first appearance on the 12-metre class yacht Australia II in the 1983 America's Cup.Along with Australia II's efficient sail design, this keel was one of the factors contributing to Australia II's success.inged keels are generally found on high performance sailboats, if they are not prohibited by class rules. They are only of benefit for yachts sailing upwind where stability and the ability to produce side force are important and if the draft is limited by the class rule.
The forward (leading) edge of the sail is called the luff, which, in a mainsail, is parallel to the mast. The aft (back) edge of a sail is called the leech (also spelled leach), which is opposite the luff, and forms the hypotenuse of the triangle.
