Jeff,

don't be hesitant the bottom has already fallen out of the Tiger and Nacra F18 prices and like your 5.7 its already fully devalued so if you bought either you'd be selling right back into the same market and unless you've all of a sudden become Glenn Ashby's closest rivel the choice of F18 won't effect your results. I wouldn't bother talking to Hobie about sails. When we replaced our Tiger sails I was able to get Main, Jib and Battens from Gashby for the same price Hobie wanted for a main without battens and I'm sure they were superior sails (didn't improve my sailing though). The only reason to buy Hobie sails is the to go to the Hobie nationals and I'm sure if you hunted around you could find some reasonable 2nd hand ones.

A new Capricorn / Viper F18 would introduce a new viable second hand class to the entry level market as everyone sold off their old boats. So in my book bring on the new Cap, it can only be good for the F18 class.
