I'm going to quote someone that we all know, who is on this forum. I like this guy, he's a good dude. He's won a LOT of singlehanded races. He builds stuff. He knows more about Ocean Planet's guts than anybody but Bruce Schwab and I have never beaten him, not ONE time on the race course. Yet he's got no "attitude" and he said something to me once that I have never forgotten. Here's a quote, or close enough.
It's not how fast you can go, it's how long you can go fast.
Philippe, you'll do what you want, but if I were you, I would say "Screw the 0.3 knots, I want a boat that will GET ME AROUND". Because a really fast boat that goes fast for a week or two or three or ten, isn't going to get you what you want. A really fast boat that takes ten people to make go fast, isn't gonna do it.
There. I've said it. I'll go back to lurk mode, again.
