Keel source
Trish, I refer you to SAIL Magazine August 1998 p52-55, but just in case you don't have the mag, the article is about cutting off a keel and casting two wings. Jay and Linda Knoll speak highly of Mars Metal (tel 800-381-5335) of Burlington, Ontario that cast the lead wings for their keel. They obtained the info from the manufacturer, made profiles and Mars cast up what they needed.There must be profiles or section drawing available for the 23. Knoll's were in Florida, and had to ship their wings. Mars does a lot of keels, maybe they have such a design available. Hope this helps.
