What it is

A vessel of two hulls joined by crossbeams and a platform, with a crab-claw sail, able to carry families, plants and animals across thousands of kilometres. It was the vehicle of the settlement of eastern Polynesia.

No ancient hulls survive; date and form are inferred from the settlement record, linguistics and the accounts of early Europeans (17th-18th centuries). The double-hulled type has no direct dating.

What it led to

  • settlement of Hawaii, Rapa Nui and Aotearoa
  • exchange among archipelagos for centuries
  • present-day revival with replicas such as the Hōkūleʻa
