A paddleboat is a type of watercraft that uses a paddle wheel for propulsion. This wheel is typically located at the rear or sides of the boat and is powered by a steam engine or a modern motor. Paddleboats are often used for leisure activities, such as sightseeing on rivers and lakes, and can accommodate passengers for tours. Historically, paddleboats played a significant role in transportation and trade during the 19th century, especially in the United States along the Mississippi River. Today, they are popular for recreational purposes and can be found in various sizes, from small pedal-powered versions to large, luxurious vessels.
