A rowlock on a rowing boat A rowlock used for rowing. A rowlock [1] (UK: / ˈ r ɒ l ə k /), sometimes spur (due to the similarity in shape and size), oarlock (American English) [2] 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. [3]
The form is a long shaft (or loom) with a flat blade on the end. Where the oar connects to the boat there is a "collar" (or button), often made of leather, which stops the oar slipping past the rowlock. Oars usually have a handle about 150mm long, which may be a material sleeve or alternatively an ovoid shape carved to fit the hands.
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 .
(The term rowlock is often applied to an oar crutch.) A rowlock may be closed when, for instance, a boat is being used under sail. Strictly speaking, this is done with a piece called a shutter, which is habitually mistermed a "poppett". An oarport is a hole cut through the side of the hull. The oar has to be passed through this hole when it is ...
The oar normally pivots in a simple notch cut into—or rowlock mounted on— the stern of the boat, and the sculler must angle the blade, by twisting the inboard end of the oar, to generate the thrust that not only pushes the boat forward but also holds the oar in its pivot.

Rowing, often 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 rowlocks, while paddles are not connected to the boat.
Man rowing in slow pace typical for long distances. In rowing (sport), 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, [1] and the extraction (also known as the 'finish', 'release' or 'tapping down') where the oar blade is removed from ...
