- 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.
Finally, don't let the one-design nazis get to you.

kinda funny --sounds more like the P rating Gustopo
YOU must know your assigned D-Pn 5 additional numbers and have your PAPERS and answer the questions or you vill be exterminated-

Maybe more like the Stallinists ,-agree with our methods or you will be called a Nazi and sent to Syberia .

just jokin with you a little -
Many people enjoy the pure simple fair aspects and truer test of sailing skill class racing and new Formula Class and development type class racing offers .
