Tangaroa Expedition Tangaroa Expedition 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. 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
Frogner century Scandinavian sea vessels - including the fully intact Oseberg ship - which were used as high status tombs. A collection of Viking weapons, utensils and talismans, buried with the ships, is also on display. The Kon-Tiki Museum is named after the raft on which Norwegian adventurer Thor Heyerdahl crossed the Pacific Ocean in 1947. Alongside the raft, the museum houses various artefacts related to Heyerdahl's other expeditions and a changing program of temporary exhibitions explores his life and work. Oslo City Museum is situated at Frogner Manor in the Vigeland park (Frognerparken). It is a museum of cultural history
