A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle. The word kayak originates from the Inuktitut word qajaq. In British English, the kayak is also considered to be a kind of canoe.
Whitewater forms in the context of rapids, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that froths, making the water appear opaque and white.
A dragon boat is a human-powered watercraft originating from the Pearl River Delta region of China's southern Guangdong Province. These were made of teak, but in other parts of China different kinds of wood are used. It is one of a family of traditional paddled long boats found throughout Asia, Africa, the Pacific islands, and Puerto Rico. The sport of dragon boat racing has its roots in an ancient folk ritual of contending villagers, which dates back 2000 years throughout southern China, and even further to the original games of Olympia in ancient Greece. Both dragon boat racing and the ancient Olympiad included aspects of religious observances and community celebrations, along with competitions.
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.
Whitewater kayaking is an adventure sport where a river is navigated in a decked kayak. Whitewater kayaking includes several styles. River running; where the paddler follows a river and paddles rapids as they travel. Creeking usually involving smaller, steeper, and more technical waterways. Creek boats tend to be short but high volume to allow for manoeuvrability while maintaining buoyancy. Slalom requires paddlers to navigate through "gates". Slalom was originally the only whitewater event to be in the Olympics but Kayak Cross - a new subcategory of slalom involving gates and more natural whitewater elements - featured in the 2024 Paris Olympics. Play boating involves staying on one feature of the river and is more artistic than the others. Squirt boating uses low-volume boats to perform special moves in whitewater features.
Outrigger boats are various watercraft featuring one or more lateral support floats known as outriggers, which are fastened to one or both sides of the main hull. They can range from small dugout canoes to large plank-built vessels. Outrigger boats can also vary in their configuration, from the ancestral double-hull configuration (catamarans), to single-outrigger vessels prevalent in the Pacific Islands and Madagascar, to the double-outrigger vessels (trimarans) prevalent in Island Southeast Asia. They are traditionally fitted with Austronesian sails, like the crab claw sails and tanja sails, but in modern times are often fitted with petrol engines.
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing.
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.
In competitive rowing, the following specialized terms are important in the corresponding aspects of the sport:
Canoe sprint is a water sport in which athletes race in specially designed sprint canoes or sprint kayaks on calm water over a short distance. Prior to November 2008, canoe sprint was known as flatwater racing. The term is still in use today but is often used as a hypernym for both canoe marathon and canoe sprint. Similarly, the term 'canoeing' is used to describe both kayaking and canoeing.
A surf ski is a type of kayak in the kayaking family of paddling craft. It is generally the longest of all kayaks and is a performance oriented kayak designed for speed on open water, most commonly the ocean, although it is well suited to all bodies of water and recreational paddling.
In rowing, oars are used to propel the boat. Oars differ from paddles in that they use a fixed or sliding fulcrum, an oarlock or rowlock attached to the side of the boat, to transfer power from the handle to the blade, rather than using the athlete's shoulders or hands as the pivot-point as in canoeing and kayaking.
Canoe diving and Kayak diving are recreational diving where the divers paddle to a diving site in a canoe or kayak carrying all their gear in or on the boat to the place they want to dive. Canoe or kayak diving gives the diver independence from dive boat operators, while allowing dives at sites which are too far to comfortably swim, but are sufficiently sheltered.
A war canoe is a watercraft of the canoe type designed and outfitted for warfare, and which is found in various forms in many world cultures. In modern times, such designs have become adapted as a sport, and "war canoe" can mean a type of flatwater racing canoe.
Paddling, in regard to waterborne transport, is the act of propelling a human-powered watercraft using at least one hand-held paddle. The paddle, which consists of one or two blades joined to a shaft, is also used to steer the vessel via generating a difference in propulsion between the two sides of the watercraft. The paddle is not connected to the boat, unlike in rowing where the oar is attached to the boat.
Sprint kayak is a type of canoe sprint held on calm water. The paddler is seated, facing forward, and uses a double-bladed paddle pulling the blade through the water on alternate sides to propel the boat forward. Kayak sprint has been in every summer Olympics since it debuted at the 1936 Summer Olympics. The sport is governed by the International Canoe Federation.
Canoeing – recreational boating activity or paddle sport in which you kneel or sit facing forward in an open or closed-decked canoe, and propel yourself with a single-bladed paddle, under your own power.
Human-powered watercraft are watercraft propelled only by human power, instead of being propelled by wind power or an engine.
Stern sculling is the use of a single oar over the stern of a boat to propel it with side-to-side motions that create forward lift in the water. The strict terminology of propulsion by oar is complex and contradictory, and varies by context. Stern sculling may also simply be referred to as "sculling", most commonly so in a maritime situation. In fresh water, and particularly in sport rowing, sculling is use of two oars on either side of the boat by each person, in contrast to sweep rowing, whereby each boat crew member employs a single oar, complemented by another crew member working on the opposite side with their oar.
