it seems like someone could get a used tiger for a decent price and be competitive right off in the f18 fleet.
Not as competitive as a new F18. The fact that modified Tigers do well in European F18 fleets doesn't mean that (stock ?) second hand Tigers are "right off" competitive in F18 fleets. We all know how serious crews buy a Tiger only to strip it completely to give it full work over before even racing the first race ? With the newer tigers this workover is less then before because Hobie are producing the boats with better sails now, but still the Tiger gets a workover like any other production F18.
