Scoring is up to the Primary Race Officer (PRO). Some of them, especially those at Hobie Regattas, are not too familiar with the Portsmouth system. So you should know what your Portsmouth Numbers are (Wind HC, not just D-PN), and be prepared to explain why in case there are any questions.

Your base D-PN should be 71.5. If your new main sail is larger than 105% of stock, than you take a modification of 0.980 (ML). The modification for a larger jib is 0.995 (JU)

71.5 * 0.980 * 0.995 = 69.7

Your wind HCs are then 73.4, 71.0, 68.0, 65.8

I recommend that you know how to calculate them yourself, and be able to explain it to the race committee. Also be sure to write down your mods (ML and JU) on the entry form.

Finally, don't let the one-design nazis get to you. Different people sail for different reasons, but overall its about having fun, and it sounds like you're having lots of fun with your new sails.
