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.
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 bowloader or bow-coxed shell is a racing shell in which the coxswain lies semi-supine in the bow, as opposed to the normal seated position at the stern.
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 a rowing crew, the coxswain is the member who does not row but steers the boat and faces forward, towards the bow. The coxswain is responsible for steering the boat and coordinating the power and rhythm of the rowers. In some capacities, the coxswain is responsible for implementing the training regimen or race plan. Most coaches cannot communicate to boat/coxswain, so the coxswain is the "coach" in the boat. A coxswain is necessary in the first place because the rowers sit with their backs to the direction of travel.
A coxless pair, abbreviated as a 2- and also known as a straight pair, is a racing shell used in the sport of competitive rowing. It is designed for two rowers, who propel the boat with sweep oars.
In the sport of rowing, each rower is numbered by boat position in ascending order from the bow to the stern. The person who is seated on the first seat is always the 'bow', the closest to the stern is commonly referred to as the 'stroke'. There are some exceptions to this: Rowers in continental Europe number from stern up to bow. Certain crew members have other informal titles and roles. Stroke seat in most cases is responsible for keeping pace for the boat, while the coxswain is responsible for the steering of the boat.
A single scull, abbreviated as a 1x, is a racing shell designed for a single person who propels the boat with two oars, one in each hand.
The men's coxed four event was part of the rowing programme at the 1920 Summer Olympics. The competition was held on 28 and 29 August 1920. It was the third appearance of the event, which had previously been held inaugural rowing competitions in 1900 as well as in 1912. Eight boats, each from a different nation, competed. The medals all went to nations that had not won a medal in the men's coxed four previously: Switzerland and the United States took gold and silver, respectively, in their debuts in the event; Norway took bronze.
A double scull, also abbreviated as a 2x, is a rowing boat used in the sport of competitive rowing. It is designed for two persons who propel the boat by sculling with two oars each, one in each hand.
A quadruple sculling boat, often simply called a quad and abbreviated as a 4x, is a racing shell used in the sport of competitive rowing. It is designed for four people who propel the boat by sculling with two oars, or "sculls", one in each hand.
A coxed four, abbreviated as a 4+, is a racing shell used in the sport of competitive rowing. It is designed for four persons who propel the boat with sweep oars and is steered by a coxswain.
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.
A coxed pair, abbreviated as a 2+, is a racing shell used in the sport of competitive rowing. It is designed for two persons who propel the boat with sweep oars and is steered by a coxswain (cox).
An eight, abbreviated as an 8+, is a racing shell used in competitive rowing (crew). It is designed for eight rowers, who propel the boat with sweep oars, and is steered by a coxswain, or "cox".
An octuple sculling shell, often simply called an oct and abbreviated as an 8x or 8x+, is a racing shell used in the sport of rowing.
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.
