Treenailed boats were use used by viking in which centuries?
Treenailed boat The treenailed boat is a boat model used in Northern Europe, usually associated with Vikings but should perhaps be ascribed to Pomeranian groups. The shape and construction coincides with the sewn boats, but instead of ropes, it is assembled with wooden treenails.
Aleutian kayak The Baidarka or Aleutian kayak was the watercraft created by the native Aleut (or Unangan) people of the Aleutian Islands. The Aleut people were surrounded by treacherous waters and required water transportation and a hunting vessel. Due to the geography and climate of the Aleutian Islands, trees and wood were in scarce supply and the people relied primarily on driftwood to create the framework of the kayak, which was covered with the skins of sea mammals. Two types of boats were created, one with a covered deck that was used as a hunting kayak, and another that was open and capable of carrying goods and people from one island to another.
