The Americas cup trim tabs are often designed according to Gabriel Heymans Patent. See http://www.heymanyachtdesign.com/in3a.html for an...
I just felt I had to make a comment here. I have sailed this boat, and I have to agree with Alex, he is quite clear in stating that the design is...
Wrong place to ask :) This is the place for designer dreams! For sailing dreams go http://www.cruisersforum.com/forums/ [[ just kidding :) ]]
Talking about prior art... (And Bertil, since you're Swedish): Actually this product was propably invented by Arvid Laurin, silver medalist...

I sailed 18 months with one of their 60l/min units. It was very reliable, and as the OP says produces more water per Amp hour than any others I...

Same reasoning why I got mine ! But it also made me become an alloy fan these days... Maybe this one :cool: ?
Hull # 100, got it new in 2000. I have no clue about later hulls, but I honestly suspect they don't care. They can't afford to. It's cheaper to...
I am not referring to performance. It is quite nice. I'm talking about the boat staying in one piece, not after a single race but after many...
