TEH- You are one anal-retentive dude, but I mean that in a good way though.

You must take alot of notes.
The actual trapezing with the spinnaker up is pretty easy. Getting in and out is a royal pain in the pooper. I'm getting more confident about it, but its tough. I think the important thing is to add a cleat for the spinnaker sheet, which I still need to add. That way all you have to worry about is the tiller when getting out, you can also cleat it for a bit and adjust mainsail trim more easily. I'm about positive that one can go faster on the wire, where I fall short is the few seconds that I've gained, I piss away getting in and out. I can't keep the spin sheeted, concentrate on steering, and get back in gracefully all at once yet.
I did manage to capsize this past weekend trapezing downwind. A wind shift not in my favor forced me to head up right before the finish line. I wasn't going to let the boat right on my heels go by so I turned up and headed at the pin end, then it shifted back with a nice gust and over I went, but I made it across the line ahead of the other boat.
Are you going to Racine?
