So let's say you go with newly developed sails...over time this improves the racing results...leading to a lowered DPN...bingo you're back with the same corrected out time issue.

I agree the N20 should get new sails and open up to other makers...just not for the reason of trying to beat F18's in specific course situations. Never liked strict single manufacturer one-designs in principle for many of the reasons being expressed on this thread.
