All Inuit groups used some form of kayak, except for the most northerly polar Inuit. Essentially a one-person closed-deck hunting craft, it was employed sometimes for transport of goods. Fast and seaworthy and ranging from 4 m to 7 m in length, it was built to hold from one to 3 persons. Covered with dehaired seal or caribou skins, the frame was often made of driftwood, with ribs of willow branches. Both single and double-bladed wooden paddles were used. To make the entire craft watertight, even when tipped, the hunter wore a parka which was tied around the hatch-hole rim.
