It ?s a beautiful boat (and a beautiful arrangement > with your foundation, too :-), but bilge keels would be easier in shallow > waters, no? This is what they came up with a few centuries ago. Bilge keels are diffucult to construct in wood. With the lee boards yoou don't need to cut a hole in the hull for the bilge keel. In principle the lee boards are more effective than a keel because they are curved like a sail and are under an angle to produce pressure into the wind direction and reduce drift in that manner. A keel however is symmetrical and therefore does not generate any extra pressure as the lee boards do. Cheers, Michiel Fokkema
