Polynesian double-hulled canoe

Timeline

1. c. -1000–-500Melanesia–Polynesia border waters · PolynesiaEarly islanders overcame the instability of single-hulled canoes by lashing floats and using double-hull structures, forming a basic load-carrying, long-range vessel type that laid the technical foundation for later transoceanic expansion.
2. c. 800–1200Samoa–Tonga cultural sphere · Polynesian TriangleLarge double-hulled sailing canoes could carry dozens of people plus grain and livestock, completing long-range migrations to Hawaii, New Zealand, and Easter Island with celestial navigation; hull proportions, sail shapes, and steering techniques became standardized.
3. c. 1291–1300Pacific islands · Pacific OceanBy the late 13th century, double-hulled canoes remained the main vessels for island chiefdoms to maintain fishing, tribute transport, and political marriage ties, with fleet sizes and sailing-season rules highly institutionalized.
4. c. 1800Hawaii and Polynesian islands · PolynesiaTraditional oceangoing voyaging declined under European colonization and motorized vessels; since the 20th century, Hawaii and other places have carried out cultural revival and experimental archaeology, rebuilding double-hulled canoes to recreate ancient transoceanic voyaging capability.
