Paddle
A paddle is a handheld tool with an elongated handle and a flat, widened distal end (i.e. the blade), used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). It is different to an oar (which is similar in shape and performs the same function via rowing) in that the latter is attached to the watercraft via a fulcrum.
Rowing
Rowing is the act of propelling a human-powered watercraft using the sweeping motions of oars to displace water and generate reactional propulsion. Rowing is functionally similar to paddling, but rowing requires oars to be mechanically attached to the boat, and the rower drives the oar like a lever, exerting force in the same direction as the boat's travel; while paddles are completely hand-held and have no attachment to the boat, and are driven like a cantilever, exerting force opposite to the intended direction of the boat.
Oar
An oar is an implement used for water-borne propulsion. Oars have a flat blade at one end. Rowers grasp the oar at the other end. The difference between oars and paddles is that oars are used exclusively for rowing. In rowing the oar is connected to the vessel by means of a pivot point for the oar, either an oarlock, or a thole. The oar is placed in the pivot point with a short portion inside the vessel, and a much larger portion outside. The rower pulls on the short end of the oar, while the long end is in the water.
Canoe
A canoe is a lightweight narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using paddles. In British English, the term canoe can also refer to a kayak, while canoes are then called Canadian or open canoes to distinguish them from kayaks. However, for official competition purposes, the American distinction between a kayak and a canoe is almost always adopted.
Watercraft
Any vehicle used in or on water as well as underwater, including boats, ships, yachts, hovercraft and submarines, is a watercraft (: watercraft), also known as a water vessel or waterborne vessel. A watercraft usually has a propulsive capability (whether by sail, oar, paddle, or engine) and hence is distinct from a stationary device, such as a pontoon, that merely floats. Most watercraft may be described as either a ship or a boat. However, numerous items, including surfboards, underwater robots, seaplanes and torpedoes, may be considered neither ships nor boats.
Galley
A galley was a type of ship which relied mostly on oars for propulsion that was used for warfare, trade, and piracy mostly in the seas surrounding Europe. It developed in the Mediterranean Sea region during antiquity and continued to exist in various forms until the early 19th century. It typically had a long, slender hull, shallow draft, and often a low freeboard. Most types of galleys also had sails that could be used in favorable winds, but they relied primarily on oars to move independently of winds and currents.
