The Tangaroa Expedition of 2006 closely resembled the Kon-Tiki expedition sailing a balsa raft from Peru to Polynesia. Tangaroa outperformed Kon-Tiki by having an improved sail rig and by actively using guaras (centerboards). As such, the expedition represents a scientific continuation of Thor Heyerdahl's experiments in recreated maritime technology. A documentary, The Tangaroa Expedition (Ekspedisionen Tangaroa), was produced by Videomaker (Norwegian), 2007, shot by photographers Anders Berg and Jenssen.
