So I understand that this thread needs some clarification on some points.

DennisMe, stating that I did not want weight to be a parameter that can be discussed here is not the same as all hell brakes loose. It certainly was not ment as it... So let's both take a chill pill.

Of course weight is a MAJOR issue in terms of performance. The thing is that weight already has been discussed over and over again in the past on this and other forums. I wanted people to come with new design aspects that would increase performance without lowering the weight, like the designers at Hobie now are trying to do. I know it would be hard, but that's what make it interesting.

I myself sail a Taipan 5.7 which indeed is 50 kilos lighter than the F18, something that still would convince me to choose the T5.7 over a F18 if I was to buy a cat today.
