Kon-Tiki II
An inspiring way of building. without nails, binding together exotic wood with sisal ropes. I've been a raftbuilder on this historical and scientific expedition project in Peru. The kon-tiki 2 was an attempt to build 2 rafts that would sail across the Pacific Ocean and back again. During this expedition they focused on testing the steering with guara boards and scientific research. One raft was specially equipped with scientific gear to take samples from the ocean.
