Rowing boats are small watercraft designed for human-powered propulsion using oars. They are typically made from materials like wood, fiberglass, or aluminum and can vary in size and shape. Rowing boats are commonly used for recreation, sport, and transportation on rivers, lakes, and coastal waters. There are different types of rowing boats, including sculls and sweep boats. Sculls have two oars, one for each rower, while sweep boats have one oar per rower. Rowing is a popular activity that promotes fitness and teamwork, often seen in competitive events like the Olympics.
