Abstract: Construction of the world’s largest existing double hulled voyaging canoe, the 108 foot Tongan Kalia Mileniume, was completed in August 2000. The kalia was documented on three research trips. Tuione Pulotu, master chainsaw artist and canoe builder designed the canoe and proposed the project to the Tongan government as a celebration for the New Millennium. This ethnobotanical study documented canoe architecture and plant species used for the Kalia Mileniume, as well as for voyaging canoes of the past.
