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 was named after the Māori sea-god Tangaroa. Based on records of ancient vessels, the raft used a relatively sophisticated square sail that allowed sailing into the wind, or tacking. It was high by wide. The raft also included a set of modern navigation and communication equipment, including

No metal was used in the construction. "Kon-Tiki" carried of drinking water in 56 water cans, as well as a number of sealed bamboo rods. The purpose stated by Heyerdahl for carrying modern and ancient containers was to test the effectiveness of ancient water storage.
