This is our 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 hulls have the proven trapezoid cross section as the PELICAN. For wind ward performance the boat has anti-vortex panels. These work a lot better as low aspect ratio keels and are not as prone to damage as boards. Besides, why spoil one of the best advantages of a multi hull, low draft, to enter coves etc a keel boat never can enter? For an explanation how these work go to this article.
The boat is, like all our boats, a (ply)wood/glass/epoxy composite construction. Any handy amateur can build this boat without difficulties and surprises. Construction time will be around 1200 hours.
