Rowing implements are tools used in the sport of rowing, which involves propelling a boat using OARS. OARS are the most common type of rowing implement, consisting of a long shaft with a flat blade at one end. They are used to move the boat through the water by providing a force against the water. Other rowing implements include sculls, which are two OARS held in the hands, and sweep OARS, which are longer OARS held by one person.
