DUO 800 fast coastal trailer sailer
The DUO 800 can be build with a sloop rig or a parallel rig.
Both are very fast coastal cruiser catamarans for the whole family. The parallel rig version will be faster because the sail area is bigger and the center of effort is lower.
It is the only eight-meter cat with a central nacelle on the market today. The nacelle sleeps four for a weekend outing or three for a holiday trip.
With a purpose-built trailer the boat can be set up in about a one hour
Construction is in the (ply)wood/glass/epoxy system. The boat has easy-to-build a-symmetrical hulls and daggerboard rudders. No lofting is required. The beams are made from standard Aluminum tubes for ease of construction.
Even amateurs new to boat building will have no difficulties building this boat. The drawings are CAD drawings.
The plans show two different hulls. The 2022 edition hulls have more volume. The nacelle now has also forward windows.
The construction description is clear to understand. The plans also include the construction of the carbon masts. With the parallel rig, the boat will be more stable.
Drawings and descriptions are included when ordering the DUO 800 plan. The masts can be built without using the vacuum technique!
