Barge[]
A barge is a flat-bottomed boat, built mainly for river and canal transport of heavy goods. Most barges are not self-propelled and need to be towed by tugboats or pushed by towboats. Canal barges, towed by draft animals on an adjacent towpath, contended with the railway in the early industrial revolution, but were out competed in the carriage of high-value items due to the higher speed, falling costs, and route flexibility of rail transport.
