Mark, I agree with the decision under your example, a sane jury would probably let that go under rendering assistance per 62.1(c).
Very educational stuff in the cases mentioned. If you can deal with the negativity, SA has a thread going with pics of the redress decisions posted at the regatta. Also very educational.
I was fortunate enough to only be on a start boat on the practice day, and we couldn't get that to anchor out there at all (swapped it out to be the gate boat). The rest of the week I was on the weather mark (with tons of rode). I got some grief from some of the BIMBOs, but none of those marks moved.
