Performance Handicap Racing Fleet San Diego
2017 Class Breaks

If a boat is within 6 seconds of a Class Break it may request to change to the next lower or higher class. This can be done only once in a calendar year or once for the upcoming or current Yearly Class Championship Series. The Board will agree or not.
The method of calculating Sail Area was changed starting in 2017 which affected the Performance Factor calculation. PF for PHRF San Diego is now different from PHRF SoCal.
PF Formula = ((0.67*LWL)+(0.34*LOA))*(SA/DISP)
OLD Formula: SA = (((J*I)/2)*1.55)+((P*E)/2)
NEW Formula: SA = ((I*(LP*0.01))*0.52)+((ISP*SPL)*0.66)+(P*E)/2
LP = 155% J or 105% J for boats only able to fly non overlapping headsail.
