I'm just say'n, if you really want to get an F20 class up and running, and you already have all these great boats, why not use them? Yeah, it might take a little time, effort and creativity but the Tornado guys are pretty good at that already.

Add in the P 19's and the Hobie 20's (with a "F20 class size" spinny) and you have a F20 class ready to go.
