Aren't you even a little embarrassed to have a 144 rating for a class legal J/30?
Did the rating change when the class allowed string head sails?
I'd bet that the year the sail material is changed (if it happens) you could go out, buy your new sails, sign the ODR compliance document and smile all the way out to the race course. You shouldn't even have to announce it
Still, where's the 6 second penalty when not ODR Compliant Normal PHRF penalties = 9 seconds
3 seconds for the head sail
3 seconds for the pole
3 seconds for the kite
