I checked with the Gulf Coast PHRF committee and received this answer:
"Currently, the J-30 is not rated to ODR specs. The J-30 is rated as a standard PHRF boat, with a J pole, 155 gennoa, and no limits on spinnaker weight. We then give adjustments for 10% increase in spin pole (including larger spinnaker), and over 155% gennoa. We have the Net rating of 138, which is where we want it for the ODR version, except we allow .5 oz spinnakers."
So it doesn't look like there would be a change in the PHRF rating anytime soon. I appreciate the feedback and the discussion.
