Just curious? Not all that concerned about fitting the rules. I don't have the money to keep an F18 for racing and my 18 as a recreational playtoy, one boat must do it all. The talk of F18's racing the Tybee is what started my thinking. Could I show up with my 18mod and be allowed to race in the Tybee? I would assume no. Thanks for the comment on EMSA allowing the boat to run as a F18, I didn't think anyone would care. I'm soo not a threat to anyone but myself.
