Canoeing is the activity of paddling a canoe for the purpose of recreation (also called a float trip), sport, or transportation. It usually refers exclusively to using a paddle to propel a canoe with only human muscle power. A kayak is propelled using a paddle with two blades where the paddler sits with their legs in front of them, whereas canoes are propelled using single- or double-bladed paddles where the paddler is kneeling or sitting. Kayaks are usually closed-decked boats with a spraydeck, while canoes are usually open boats. There are also open kayaks and closed canoes. Technically, a kayak can be seen as a special kind of canoe. 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.
Open canoes may be 'poled' (punted), sailed, 'lined and tracked' (using ropes) or even 'gunnel-bobbed'.

(a) top view, (b) axial viewKayak paddles in which the blades are in-line when viewed from an axial standpoint are called "un-feathered" and ones such as in the image are called "feathered". Feathered paddles are measured by the degree of feather, such as 30, 45, or even 90 degrees. The paddle in the image to the right is feathered around 15 degrees. Many modern paddles can be adjusted by the user for feathered or unfeathered settings. The shaft is normally straight but in some cases a 'crank' is added with the aim of making the paddle more comfortable and reduce the strain on the wrist. Because the kayak paddle is not supported by the boat, paddles made of lighter materials are desired, it is not uncommon for a kayak paddle to be two pounds (32 ounces) or less in weight.
