Bob,I don't think there ever was a Scheel builder. But Henry Scheel worked at S&S fore years before going out on his own. He was a very talented designer with a good eye. I was never crazy about the Scheel keel but it did do the job of lowering the VCG on a shoal draft keel. Morgan built a series of Scheel boats called the Morgan 452. It's a nice looking center cockpit boat.
I'd have to see a photo to tell what your keel was. I don't think Mark used the Scheel keel but he could have designed a "Scheelish" keel. Mark isn't the type to steal another designer's idea.
Publish a pic of your keel if you have one. Could be the term "Scheel keel"was just a convenient, generic way of saying the keel was Sheeelish.
I'm afraid you're mistaken, Hudson..Here is some info on Henry Scheel, the Scheel Boatworks, and the Scheel keel:From Whence We Came - Issue 102 | Maine Boats Homes & Harbors
Jiminri: Your keel does not look like Scheel keel, which had winglets to create an endplate effect. As I recall, Steve Killing and Douglas Hunter cover this well in the book, Yacht Design Explained
The Schell keel created a huge stir when Austrailia won the 1983 America's Cup with a boat with a Scheel keel. Dr. Stuart Walker Stuart H. Walker - Wikipedia, the free encyclopedia, who covered the America's Cup for ESPN, told me that from above in a helicopter it was clear that when going to windward the Aussie boat didn't pitch and roll as much as its American counterpart. Dr. Walker said that the elipse described by the tip of Aussie boat's mast was much small than that of the American boat, therefore, the trim of sails more frequently accurate.
... but I'd suggest even that's a bit of a stretch...Scheel Keel was a precursor to the famed winged keel used by the Australians to win the America's Cup.
