Frenchie, I am a skeptic, too. Who are you? You are an anonymous poster on this forum. You have not given your name or your e-mail or your location or anything about you. Have you ever sailed a catamaran -- or any kind of sailboat? I have read all your posts and seen no indication that you sail at all. Oh, yes, I finally found one post where you said something about experiencing speed and getting wet on a Formula 40 and some other boats, but you did not elaborate on that at all. If you expect people to take you seriously, you have to at least exist and at least sound like you are a sailor instead of just a mathematician, or whatever it is that you are.
I don't know why people are being so polite to you and not arguing, because EVERYBODY knows you are wrong. Maybe I can get away with it because I am a woman. When numbers are put in the picture, men tend to get intimidated and say, "Wow, this guy must know what he is talking about. I don't dare contradict him." I don't know why Jake said he did not doubt you ( just being polite, I guess), because so far you have not given us any reason to believe you.
But I have been sailing cats a long time, and I know that what you are espousing is pure bunk.
