Sounds like PHRF-MA is unique in allowing +3 benefit for a ODR, i.e., 138, versus the more common 141-3-3 ala carte PHRF rating. I don't know what inspired the ODR versus standard rating, but it creates the technicality that any non-OD change, even if not normally a penalized change (like sail material, chute weight), prohibitss the boat from carrying the ODR - instant cut to 135. The loophole at the margin is what the class defines as OD, not what PHRF penalizes. I would sail 135 with non OD sails, except I can't afford the double inventory and would like to sail a few OD events per year. Would also like to know along with Steve the rating of S2-9.1s in other districts.
