Sculls are long, narrow boats used in the sport of rowing. They are designed for one or more rowers, who use oars to propel the boat forward. Each rower in a scull typically has two oars, one in each hand, allowing for a smooth and efficient stroke. Sculls are often made from lightweight materials like carbon fiber or fiberglass to enhance speed and performance. In competitive rowing, sculls can be classified into different categories based on the number of rowers and the type of oars used. For example, a single scull is designed for one rower, while a quad scull accommodates four rowers. The sport of rowing is popular worldwide, with events held in various formats, including the Olympics.
