J/30 Class Association Forums J/30 Forum One Design Class Rules Handicap rating

In PHRF BC They base rate the yacht at 145 and then punish it for all oversize sails meaning the OD rating of the boat is 139. I sail with a Code 6 main and a smaller 153 #1 at 139. I plan to up my spinnaker size by 3 feet on the hoist to be 136 and get more downwind power.

When I bump across the ditch and race PHRF NW, I lose 1 second to 138. I can confirm that is the OD rating for NW.
