Is it "the FAD" we see go upwind? <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" /> Nice trapeezing, but look at the mainsheet and mast. Looks like mainsheet is very tight, and that's probably where his windward ability lies.
Like have been said, trapeezing that low is difficult in large waves. You will not fly a hull all the time, and then it is very easy to be washed overboard. Setting skippers trapeze static in that height while leaving the crew free to adjust his trapeze can be an exercise in how to manage your teamwork in strong winds..
Juana's look very nice! Seeing events like that while we have 9degC outside is tough.
