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?
Assume a glass-smooth finish. The problem as I see it is that, according to boundary layer theory, that very first layer of water next to the hull is going at hull speed
no matter what the surface is. So unless that magic coating can allow that first layer of water slip by in violation of the theory, what's to improve on?
