This design was costing me more time as I  thought it  would. But the result is precise what I wanted. An easy to built pocket cruiser with a  lot of possibilities for the weekend sailor to.
With its beam of only 2,30m (7 feet 8 inches) easy to trailer.
Quick to set up on the sailing ground . The windsurf masts with and the extensions are set in minutes  and you are ready to go.
Fast sailor which can handle a lot of wind through the low center of pressure of the biplane rig. The sails are wound around the masts for easy of handling. Furling and un-furling  can be handled from the cockpit. The asymmetrical hulls need no boards or keels to sail very well to windward. 
The cabin is small, but big enough for two persons to even sleep on the boat. The cockpit has a good size for exciting or lacy days on the water.
Best of all, you would be not be broke at launch day.
The boat is not expensive to build.
The boat is easy to build to. An average amateur can built the boat in about 300 hours.
We use the time proven matched hole technique adapted from aluminum aircraft
construction. No strong back is needed to build the boat. The a-symmetrical hulls are self aligning.
Like all my other designs the proven plywood/ glass/Epoxy system is used.
A lot of hardware can be build to safe money, for example gudgeons, sail rollers, booms and boom rotator.
40 drawings and an almost step by step instruction will give the builder the confidence to successful build this boat.
