Well it is important that you get the 6.0's rules officially changed. At a Nationals the rules state that the boats will be sailed according to their class One-Design Rules. So any boats with these chutes would not be class legal and not qualify to be sailed.
It sounds like you have a good proposal put together that needs a few more specifics and just need to mail it to Performance to either ratify or send out to the class members for ratification.
We went through this process with the changes to the P19 and the changes went through.
When you install the rule I wonder what PN number we will be using for the 6.0 in distance racing. Will it change to be like the I20 and get it's own number with the chute or will we continue with the modification factors. If you go with a new set of numbers for the new configuration what do race committee's do with 6.0's that show up with a 450^2ft chute? My thought is that we add a new row with 6.0 and class chute with it's own number. If a boat shows at a race with the bigger chute they would take a bigger hit by adding the chute modification factor to the regular 6.0NA.
