I think what you are saying does make sence, but taking your argument from a logical starting point: When the person first tied two tree tunks together and put branches across it he invented the 1st catamaran, therefore every step since then has been a development and not an invention. Development is the key word here. The designer has never claimed to be reinventing the wheel, and yes we may have seen all the bits before on different boats.... but have we seen all the bits on the same boat?

The main point is yes it looks nice (to the majority) yes there is some development to do on the rig and the foils, but I don't think you can blame anyone for using marstrom rudders as a starting point...... THEY WORK!!!! And lets see what happens in the market place and in the sailing world when production starts.

Being sceptical is one thing but let it not stop development. Remember nothing ventured nothing gained.
