Tangaroa Expedition

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.

The raft also included a set of modern navigation and communication equipment, including solar panels, portable computers, and desalination equipment.

[3] Tangaroa's six-man crew was led by Norwegian Torgeir Higraff and included Olav Heyerdahl, grandson of Thor Heyerdahl, Bjarne Krekvik (captain), Øyvin Lauten (executive officer), Swedish Anders Berg (photographer) and Peruvian Roberto Sala.

Tangaroa's speed was credited to the proper use of the quara centerboards in navigation.
