Rowing vessels are boats designed for propulsion through water using oars. These vessels can vary in size and shape, ranging from small skiffs to larger galleys. Rowing is an ancient method of transportation and recreation, often used in competitive sports, such as crew or rowing competitions. Typically made from materials like wood, fiberglass, or aluminum, rowing vessels are lightweight to enhance speed and maneuverability. They can be powered by one or more rowers, each using oars to push against the water. Common types include sculls, which have one or two oars per rower, and sweep boats, where each rower has one oar.
