A canoe is a lightweight narrow boat, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel using a single-bladed paddle. In International Canoe Federation nomenclature used in some European countries such as the United Kingdom the term canoe refers to kayaks, while canoes are called Canadian canoes. Canoes are used for racing, whitewater canoeing, touring and camping, freestyle, and general recreation. The intended use of the canoe dictates its hull shape and length and construction material.
