I''m new to racing and have been trying to figure quite a few things out. Is there a formula to convert a Portsmouth rating to PHRF? I''ve looked a little on the net, but haven''t found anything yet.
No there isn''t a formula to convert one to the other. PHRF ratings are somewhat more subjective based on a historical performance record of a class or an interpolation of similar boat ratings. I belive that Portmouth uses a formula to rough out a rating.
