Sorry Russ, but the idea would be to make a class mainsail available to a PHRF racer who doesn't have one in order to sail at the NA's, kind of like the loaner boat. You wouldn't get to take it home after the regatta or put your number on it, except temporarily while using at the NA's. Used only six races a year, it should last a good long while.
Melges 24 never reached critical mass here and probably never will. Meanwhile the J/22, J/24 fleets are both active and stable. Etchells came to these parts relatively recently while J/80s only are just now getting organized. J/105s peaked at 43 boats back in 2007 down to 23 in 2009. Bet you can you guess what all have in common with the J/30?
