In the 18th and 19th centuries North Carolina settlers built log canoes (or "kunners") that were larger and more sophisticated than Native American canoes. Kunners were typically made from cypress trees. Sometimes two (or even three) logs were split down the middle and joined together with planks. The North Carolina Maritime Museum in Beaufort has a twenty foot kunner built in Hyde County in the 1870s.
