The DUO 425
was the first parallel rig cat designed for amateur construction. The prototype
was shown on the boat show in Duesseldorf 1984. We have the most experience with
this sort of rigs. Many very fast and record breaking catamarans used and use
this configuration.
I lost count how many DUO 425 are sailing worldwide, but it has to be more as 1000.
This is the easiest to build cat imaginable.
For example, a hull is build from only 16 main parts.
The boat can handle a lot of wind. We sailed the boat till wind force 9 without any problem. And belief me, the boat was faaaast !
The hulls are wood/epoxy constructions. Made from 4 sheets of 4 mm and one sheet of 8 mm plywood + 6 kg of epoxy. The rigs are two wind surfing rigs. Vertical kick-up rudder automatic. Sort of "matched hole technique" used to line up i.e.built the hulls. The construction time is about 120 hours
