ARE YOU FOR REAL!!!! Lets see you managed to list off two classes of multihulls, you forgot the G class. Now lets look at the monohull fleet, IRC mixed bag fleet, Open 40, Farr 40, GP42, TP52, TP62, Open 50, Open 60, Volvo 60, Volvo 70, mini-Maxi, IACC, Wally Fleet maxi's, Maxi, Maxz86, Super Maxi, plus a bunch more.
You do nothing but emphasize my point - there are too many classes. Here's a thought; instead of having 20 classes that each have about 12 boats, let's have 4 classes that each have 60 boats.
