Totally agree Jeff.

While I am a little ways off building one of these yet (kids are 2 and 6 months). I can certainly see one sitting on top of the blade in a few years time. I think a 70kg F12 will struggle against the 50kg arafura's in australia too.

The reason I am so interested in the project is because it is what I wanted when I was sailing the AC. Modern hull shape (back then it was the A Class/Taipan/Nacra/AO), high aspect mainsail, daggerboards, two on trapeze. I designed lots of these as a kid and even made a model one. My design also had an asymmetric spinnaker which I copied from the 18 foot skiffs. Everybody laughed at me at the thought of a spinnaker on catamaran.
