Paul, if I understand your question the issue is between the J/30 _PHRF Base Rating_ and the J/30 _One-Design Rating_. As I understand PHRF, in most places the basis for a rating is a genoa no larger than 155% LP and a spinnaker/pole no longer than the "J" dimension. Whenever a boat is raced in any other configuration, the rating is adjusted. Some PHRF regions have begun rating one-design boats in the one-design configuration -- What a concept!! Of course for the J/30, that means a 163% genoa and a "J + 1 ft" pole with matching spinnaker. It sounds like your area gives you the one-design (i.e. class legal) option.
Dyk, I'm not a PHRF expert by any means, but your post is the first time I heard of PHRF assessing a 3 second penalty for the pole and another 3 seconds for the matching spinnaker. I thought most places just assessed 3 for the genoa and another 3 for the pole/spinnaker combination.
