Designers data and info pack:

KD 860 - offshore catamaran

This is K-Design's or Bernd Kohler's smallest offshore cruiser. A sea worthy fast cruiser catamaran for a family of four. The performance of this boat is exceptional on all courses to the wind. To make sure of this, the boat is light and has a low streamlined profile for windward performance. The study plans include diagrams for speed prediction and dynamic stability, so you can see for your self.

The boat is a plywood/glass/epoxy composite construction. Any handy amateur can build this boat without difficulties and surprises. Quoted in it Study plans "Every person who has repaired a chair can build this boat"
