A kayak is a small human-powered boat. It typically has a covered deck, and a cockpit covered by a spraydeck also known as a skirt. The kayak was used by the native Ainu, Aleut and Eskimo hunters in sub-Arctic regions of northeastern Asia, North America and Greenland.
It historically was, and often still is, propelled by a double-bladed paddle in the hands of a sitting paddler. Modern kayaks come in a wide variety of designs and materials for specialized purposes. Kayaks are in some parts of the world referred to as canoes.
Traditional kayaks typically accommodate one, two or occasionally three paddlers who sit facing forward in one or more cockpits below the deck of the boat. If used, the spraydeck or similar waterproof garment attaches securely to the edges of the cockpit, preventing the entry of water from waves or spray, and making it possible, in some styles of boat, to roll the kayak upright again without it filling with water or ejecting the passenger. Inuit/ Eskimo Kayaks are a type of a generic class of boat of Canoe Shape.
European Canoeing clubs and associations of the 19th Century used similar craft to what are now called Kayaks, but referred to these as types of Canoe. This explains the naming of the International and National Governing bodies of the sport of Canoeing. John MacGregor (sportsman)
