Been there, done that. As Matt and I have noted, all of this is great on paper, but tends to fall apart on the water. Once you have 4-6 fleets on the same course, especially with the wide variation in talent within those fleets (leaders at the gate while last place is still going to weather), change marks become useless in a practical sense.

This could work well when you're running 2-3 fleets, so long as the course length and strength of the fleets keeps the fleets separated from one another.

No one is saying not to do it, but they are not comfortable with the idea. While I'm open to try new things, I'm learning to be more conservative to avoid abandoning races because I've gotten "too cute." Haven't had to do it yet, don't want to start now...

BTW, assuming there's wind, there's no bobbing at my regattas. I sometimes need to force myself to slow down so people can have a break between races. smile
