project goals

build live aboard skin boat launch: fall 2004

description

cruising multihull sailboat– 50’ flexible skin on frame– construction by one skilled worker with a part time assistant

– can be built anywhere– building time: 1 year

why a skin boat?– superior strength/weight ratio– test theory that flexible hull shows better flow characteristics than rigid one

– no corrosion or delamination– low cost– lashings = cheap labor

wish list1. has to withstand offshore

environs2. cost under $40,000.3. top speed 20kts4. beachable5. comfortable live-aboard:
