Some canoes are called kayaks. When exactly a canoe can be called a kayak is difficult to determine though, and often arbitrary. Internationally, the term canoeing is used as a generic term for both forms though the terms “paddle sports” or “canoe/kayak” are also used. In North America, however, ‘canoeing’ usually refers only to canoes, as opposed to both canoes and kayaks. Paddling a kayak is also referred to as kayaking.
