As to a priority, this post is respective to a I-17 normal in a open class situation.
1. Clean air start
2. Clean air up-the-course
I had many instances, where I started with-the-crowd, and the Uni did not have clean air. She could not beat a H16 as for speed or point!
I learned that CLEAN AIR for the I 17 is #1.
I have even given the 'first line' 5-6 boatlenghts at the start, just to get them out of the way, then I just get my boat dialed in, the I-17 beats then at the 1st crossing, they pull their hair, I just keep singing.
Also, I find that upwind, to stay away from the other boats, for the reason of clean air, is a powerful key to success. Even to the point of choosing this aspect over favored tack.
It is definately the 'anti-crowd' aspect. It works.
