In theory, what Sailon is saying is correct. But in practice, it doesn't seem to work quite that way. As long as we can certify we are in full one design configuration, our PHRF rating is pretty much bulletproof because there is such a long history and the boats are all alike (this works against sailors who are underperforming, as they don't have much ability to appeal for a favorable rating). When the class has made adjustments to the one design rule (carbon pole,aramid headsail cloth, self tacking traveler, power assisted vangs for example) which add some performance, PHRF has never seen fit to adjust the rating for the entire class. My guess is that the same would be true for the addition of a .5 chute to the inventory-IF it is permitted by the one design rule.
