But to answer your question, the P number is the same, so it should make -no difference- in an "Open Class" regatta, if the boat is raced Sloop one day and Uni the next, right?
Your arguement simply does not hold water. That's like me saying I'll sail heavy when it blows and then change crew to sail light when the breeze softens. Same DPN, but CLEARLY UNFAIR! So Tim if you change your conifiguration once the regatta has started and don't clear it with EVERY sailor in the fleet then yes you run a good chance of getting flicked!
