Stewart,

The F18 class is a wonderful way to race head to head without a corrected (portsmouth rated) time handicap. Yes, there are boats available on the used market. It depends on what you want to do. Sure, you can pick up an older NACRA for a fire sale price. This is due to the fact that NACRA totally changed their F18 hull design at least three times (Inter to F18 to Infusion) basically making the older boats obsolete. The Tiger is not without changes too. But the hull design remains the same as originally designed. Maybe thats why the Tiger might be higher priced on the used market. It's the preverbial arms race <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" /> CRAM is a great organization if you want to race. But be warned...the F18 class within CRAM is basically dead after the vast majority of their F18 membership jumped ship to the Inter 17. Of course you could always race on corrected time in the open fleet but that's not what F18 is all about.

There is a very active Hobie Tiger circuit in western NY (just up the road from you) and Ontario (Hobie Division 16) that we partake in. About a dozen Tiger F18's in attendance on average. Anyway just a few more data points to consider in your quest.
Cleveland has some great waves this time of year. Ever try surfing? <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />
