In Lake Ontario PHRF, the 186 is without a spinnaker. Otherwise 168 is the standard rating.

We have two-three well sailed J's and they are hard to beat at that rating. I can not imagine a 186 with a spinnaker :)

:: Thanks for the comment, Bob. I was mistaken, the J24

:: J-Boats site that they say the rating is 171. We'll be
:: looking into this before next year. I'm not sure where
:: the 186 came from. The J at our club is dry sailed which
