This design was costing me more time than I thought it would. But the result is precisely what I wanted. It is an easy-built micro cruiser with many possibilities for the weekend sailor.
Its beam of only 2,30m (7 feet 8 inches) makes it easy to trailer.
Quick to set up on the sailing ground. The windsurf masts and the extensions are set in minutes, and you are ready to go.
A fast sailor who 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 handling. Furling and unfurling can be handled from the cockpit. The asymmetrical hulls need no boards or keels to sail very well to windward.
Unusually, we use only one rudder with a rudder automatic. When you hit an object, the rudder jumps up. Asymmetrical hulls and a single rudder? Praxis has proven coming about is easy. A biplane rig can only work principally on the wind. The boat is fast enough to do so. To slow before the wind? Cross like ice sailors do before the wind.
The cabin is small but big enough for two people to sleep on the boat. The cockpit is a good size for exciting or lazy days on the water.
The boat is not expensive to build.
The boat is easy to build. An average amateur can build 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. See drawing
The environmentally friendly and proven plywood/ glass/Epoxy system is used like all my other designs. By the way, modern Epoxies are non-toxic. Ask your supplier.
Some hardware can be built to save money, for example, gudgeons, sail rollers, booms, and boom rotator.
Forty drawings and almost step-by-step instructions will give the builder the confidence to build this boat.
