Rowing, sometimes called crew in the United States, is the sport of racing boats using oars. It differs from paddling sports in that rowing oars are attached to the boat using oarlocks, while paddles are not connected to the boat. Rowing is divided into two disciplines: sculling and sweep rowing. In sculling, each rower holds two oars, one in each hand, while in sweep rowing each rower holds one oar with both hands. There are several boat classes in which athletes may compete, ranging from single sculls, occupied by one person, to shells with eight rowers and a coxswain, called eights. There are a wide variety of course types and formats of racing, but most elite and championship level racing is conducted on calm water courses 2 kilometres (1.2 mi) long with several lanes marked using buoys.
A dinghy is a type of small boat, often carried or towed by a larger vessel for use as a tender. Utility dinghies are usually rowboats or have an outboard motor. Some are rigged for sailing but they differ from sailing dinghies, which are designed first and foremost for sailing. A dinghy's main use is for transfers from larger boats, especially when the larger boat cannot dock at a suitably-sized port or marina.
A paddle is a handheld tool with an elongated handle and a flat, widened distal end, 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. It is different to an oar in that the latter is attached to the watercraft via a fulcrum.
Rafting and whitewater rafting are recreational outdoor activities which use an inflatable raft to navigate a river or other body of water. This is often done on whitewater or different degrees of rough water. Dealing with risk is often a part of the experience.
A cutter is a name for various types of watercraft. It can apply to the rig of a sailing vessel, to a governmental enforcement agency vessel, to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships.
Sculling is the use of oars to propel a boat by moving them through the water on both sides of the craft, or moving one oar over the stern. A long, narrow boat with sliding seats, rigged with two oars per rower may be referred to as a scull, its oars may be referred to as sculls and a person rowing it referred to as sculler.
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 watercraft, a racing shell is an extremely narrow, and often comparatively long, rowing boat specifically designed for racing or exercise. It is equipped with long oars, outriggers to hold the oarlocks away from the boat, and sliding seats. The boat's long length and semicircular cross-section reduce drag to a minimum. This makes the boat both fast and unstable. It must be balanced by the rowers to avoid tipping. Being able to balance – or "set" – the boat while putting maximum effort into the oars is therefore an essential skill of sport rowing.
In competitive rowing, the following specialized terms are important in the corresponding aspects of the sport:
A rowlock, sometimes spur, oarlock or gate, is a brace that attaches an oar to a boat. When a boat is rowed, the rowlock acts as a fulcrum for the oar.
The York boat was a type of inland boat used by the Hudson's Bay Company to carry furs and trade goods along inland waterways in Rupert's Land, the watershed stretching from Hudson Bay to the eastern slopes of the Rocky Mountains. It was named after York Factory, the headquarters of the HBC, and by some accounts was supposedly modeled after the Orkney yole. Two variations to the York Boat were scows and "Sturgeon Heads."
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.
In rowing, the stroke is the action of moving the oar through the water in order to propel the boat forward. The two fundamental reference points in the stroke are the catch where the oar blade is placed in the water, and the extraction where the oar blade is removed from the water. After the blade is placed in the water at the catch, the rower applies pressure to the oar levering the boat forward which is called the drive phase of the stroke. Once the rower extracts the oar from the water, the recovery phase begins, setting up the rower's body for the next stroke.
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.
Boats used in the sport of rowing may be adjusted in many different ways according to the needs of the crew, the type of racing, and anticipated rowing conditions. The primary objective of rigging a boat is to accommodate the different physiques and styles of rowing of the crew in such a way that the oars move in similar arcs through the water, thus improving the crew's efficiency and cohesiveness.
A coxless four, abbreviated as a 4- and also called a straight four, is a racing shell used in the sport of competitive rowing. It is designed for four persons who propel the boat with sweep oars, without a coxswain.
Sweep rowing is one of two disciplines of the sport of rowing. In sweep rowing each rower has one oar, usually held with both hands. As each rower has only one oar, the rowers have to be paired so that there are equal numbers of oars on each side of the boat. In the United Kingdom, rowing generally refers to sweep rowing only. The term pulling was also used historically. In the other rowing discipline, sculling, each rower holds two oars, one in each hand.
A remèr is a craftsman specialised in the making of traditional rowlocks – called fórcolas – and oars for Venetian boats.
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.
