Originally a stone ax chopped light wood of the trunk, was purified from its branches. The man fell on the trunk and floated working feet. Certain improvements in this simple craft was to pinpoint the deck. The next step was stesuvannya convexity, because the flat surface swimmer convenient piyaz salatasi lie. Boat deck became after people started to excavate piyaz salatasi or burn it recesses for the paddler. By the way, oar rowing evolved gradually from the board and are in very ancient times became lopatopodibnoho modern look.
