We do a couple of regattas on Hartwell too - Spring Fever (one of the largest catamaran regattas in the US) takes place only about 4 miles up the lake from where you are. The Western Carolina Yacht club does not have a very active catamaran fleet. The Keowee Sailing Club does have some very active catamaran sailors and you are welcome to join us. Even if you don't bring your boat, someone is always looking for crew. I'll send you some contact information if you guys are ever interested.
