What is the Data on the lake say? PHRF can't change the rating of a boat like the J30 with all the data out there based on the one boat. I would question that. On Lake Ontario we all carry the class legal 163% and take the 3 second penalty for it. Our rating is 135 with the class legal #1. Given that if you are using the 2 you should get +3 from the base flying sails rating. I would contact your regional PHRF chairperson and ask why the J 30 is getting another look on your lake. They should not change your rating based on your boat. It should be based on the Data for all the boats.
