Its kind of an apples and oranges comparison as Todd noted, a team vs one up, and yes Wouter got off track, the original question was "how does the sailing talent at the Acat NA's stack up against the Tybee500."
If you look at the total list of sailors at both events the Acat Na's has more medals, and championships and a deeper bench.
Not to take anything away from the Tybee sailors, the Tybee is an amazing race, and its way tougher than sailing a cuple of bouy races on an acat. Its on my list.
