A river vessel is a type of boat that is used to travel on rivers. The most common types of river vessels are barges, rafts, and canoes. Barges are large, flat-bottomed boats that are typically used for commercial purposes such as transporting goods and materials. Rafts are simple boats made from logs or other materials that are tied together and used for transportation or recreation. Canoes are small, lightweight boats that are propelled by paddles and are often used for recreational activities.
