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. 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 construction material. Historically, canoes were dugouts or made of bark on a wood frame, but construction materials evolved to canvas on a wood frame, then to aluminum. Most modern canoes are made of molded plastic or composites such as Fiberglass. Until the mid-1800s the canoe was an important means of transport for exploration and trade, but then transitioned to recreational or sporting use. Canoeing has been part of the Olympics since 1936. In places where the canoe played a key role in history, such as the northern United States, Canada, and New Zealand, the canoe remains an important theme in popular culture. Canoes can be adapted to many purposes, for example with the addition of sails, outboard motors, and outriggers.
