Seafaring was never a European monopoly. The Caribbean was settled in deliberate migration waves, the Taino crossed it in ocean-going dugouts that gave English the word canoe, and the north had its own blue-water traditions in Pacific Northwest cedar whaling canoes and the Chumash tomol. Colonial figures for canoe size are flagged as likely inflated.
The number, timing, and staging of Caribbean migration waves are actively debated, as is what happened to Archaic islanders. Genetic data point toward large-scale replacement in the Greater Antilles. Largest-canoe capacities rest on colonial chroniclers.
