One might consider the F 16. They race the boat singlehanded - main and spinnaker.
There should be plenty of used ones in Europe.
It has a lively feel ... like driving a sports car.
You mean catamarans from the F16 catamaran class, or a specific one. I have read about the Blade and Razor from Phill Brander. I have also read about the Paper Tiger Catamaran.
