Description
DUO 800
The DUO 800 is the biggest of my a-symmetrical catamarans which can be built on any flat surface, a floor or big table. This means that you safe a lot of time and material from the beginning. See the video how it works
Long journeys have been made with this boat. For instance from the Netherlands to Norway. Or quick trips from the Netherlands to the UK.
The boat can be built with a parallel (biplane) (picture shows the boat built in India) rig, or as a normal sloop. The room in the nacelle speaks for it self.
