Malihini

035DESIGN
John Shuttleworth designed catamaran with round bilges, plumb bows and dagger board in each hull. Flush decks and open cockpit aft; companionway with hatches steps down to cabin areas in each hull.

Video of Shuttle 31 Atlantic Crossing
Students at a high school in Switzerland built two Shuttle 31s. 4 feet shorter than Malihini. Two other groups of students from the same school sailed them across the Atlantic and back. The video they made is in German with English subtitles. Well worth the watch.
