Am not sure, but ...
Am not sure, because I cruise more than race, but the few "fun" races I participate in, even on the same water [Chesapeake Bay], come up with different PHRFs, i.e., I believe there is a sort of "universal" rating, and then "local" ratings ... I am in the Chesapeake, which has different racing conditions than perhaps, say SFO Bay ... And, yes, I am happy when I get the higher number ... My '89 Hunter 30' fractional rig has been rated between 186 and 205. And the races I have participated in, LOWER the PHRF for foresails 150% or greater, including gennakers, drifters, and genoas ... I have had the production 110% Yankee cut jib, and then used my gennaker, so, in the end, that combination hurt me, even tho I placed in the race!
