Steveh,
He may not have the credentials your looking for but Jack Sammons wrote on this subject in his book Welcome to A-Fleet. I think he's in the sailing hall of fame on this site. He discusses the various drag layers and does not recommend wax for racing. Though the book is written for the Hobie 16 it has a lot of good info and is well worth reading. It's also fun to read. Problem is I don't know if it's still in print. Someone has to have a copy.

Rick, did you use regular RainX or the concentrate that you add to the water in the washer fluid tank?
