The DUO 900
was designed for a French client. He wanted a trailer catamaran
which is suitable for channel and coastal cruising. This is the reason
why the original design has a beam of only 4.00 m over all. The boat
have had to be a trailer catamaran. So there where many restriction.
One of these is the beam on the trailer. In Europe in general the
maximum trailer beam is restricted to 2.53 m. This restricts the hull
beam to 1,25m. As you can see on the lay out, the boat has sufficient
accommodation for three persons. The figure in the left drawing is 1,82
The hulls have a-symmetrical cross section. This means no boards or keels are necessary.
Construction is the proven (ply)wood/glass/epoxy system. The boat is easy to build. Also beginners will need not more as 900 hours construction time.
The boat is mainly build from 8 mm plywood on stringers. In the end this is the simplest way to build.
If you are interested on this boat send me an email. The boat can be
alterd to meed your personal requirements as far as this is possible in
the basic design. Example, an other customer has opted for a more beamy
boat, so we altered the beam to 4,2m. The basic costs for the plan is € 300,- by the way.
After many requests, here the study plan for the DUO 900 (costs: Euro 10,-)
These consists of 12 pages including drawings, drawing list and list of materials
Plan costs Euro 300,00
