Indeed the H20 is a beautiful boat with a good following in some areas. I dont think there are any new ones being sold(correct me if Im wrong), so the class may want to invigorate itself. I think you should start with a new main and jib, leave everything else alone. See how the class rsponds to these changes. Put out a poll, or sail the boat DPN with the new sail package. If you are not sailing with a fleet of 20's, then do what you want. Make the boat more exciting and attractive for you. If you start kicking booty, then maybe it will catch on.
Have fun!
