A kayak is a small, narrow watercraft which is propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic language, where it is the word qajaq (pronounced [qajaq]). In the UK the term canoe is often used when referring to a kayak. Kayaking is the use of a kayak for moving across water. It is distinguished from canoeing by the sitting position of the paddler and the number of blades on the paddle.
