So we know that the PHRF rating does not apply here- this is just for fun. If we are just talking about UPWIND, what do you think the rating would be for a Tiger or Wildcat? For instance, a J109 rates in the 66-72 range, should an an F18 beat them upwind? How much slower or faster? I have sailed on many PHRF boats but never been on the water at the same time on a cat.
