Thanks Simon. Must have been more tired than I tought last night, after a 14 hours working day, it is very clear now.
I remember we tried about 90degrees rotation and a tight sheet three years ago going upwind in what you describe as light conditions. It felt slow and bound up, but I dont remember if we had a large separation bubble on the windward side or what. This was before we had a GPS, so we will definately put it in the "go fast" book and test it again as soon as possible.
Mike, I noticed what you wrote in your excellent report from MORC and the NAs about how to run downhaul. It makes a lot of sense, and Charlie is an autorithy.
In our prevailent conditions we have quite strong gusts when on the trapeze. We need to run the downhaul, or dump armloads of sheet combined with luffing up. Of the two, we choose the latter.
