I beleive it was not PHRF but the IOR rules that had the ton classes. it is a measurement rule formula. instead of having a handicap rating and winning on corrected time like PHRF. the boats would be built to fit into a ton class set of measurments so all the boat in a class would be equal in performance and be racing for first place with no handicap time penaties. it was more exciting then PHRF because you always knew where you were in the race like one design racing. but you needed a new design every couple of years to stay compeditive so it was very expensive to race not like PHRF isn't expensive.
