Treenailed boats were use used by viking in which centuries?
Vikings Vikings (Old English: "wicing"—"pirate", Danish and Bokmål: "vikinger" ; Swedish and Nynorsk: "vikingar" ; Icelandic: "víkingar" , from Old Norse "víkingar "), were Norse seafarers, mainly speaking the Old Norse language, who raided and traded from their Northern European homelands across wide areas of northern, central and eastern Europe, during the late 8th to late 11th centuries. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Viking home communities during what has become known as the Viking Age. This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily.
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.
