Understand the boredom issue well, Rick. As a H16 racer, B marks are boring (follow the leader), unless it's blowing like stink.

As for constrained resources, your best bet is Plan B above. Your diagram already shows all the marks you need (just make the yellow finish pin yellow). You just need one set of eyes watching each side of the signal boat.

I misread your orange course, and now that I see it again, it should be:

S-A-B-C-B-C-B-C-F

Yes, that will be a screaming reach finish for orange, but it will help you a ton because everyone will want to finish at the orange pin, giving LOTS more separation from the barn doors coming down to the yellow finish line.

It's also strategically better for the sailors because it keeps the passing lanes open longer (B-C leg then short reach rather than B-F follow-the-leader down the whole course).

Hope this helps.
