This category is generally for large, steel, working barges. Sites for yards which construct or repair narrowboats, wooden barges, and small canal barges are generally listed under Business/Consumer_Goods_and_Services/Watercraft/Boats/Canal_Boats.
A barge is a flat-bottomed boat, built mainly for river and canal transport of heavy goods. They may also be used as service platforms for marine construction and other activities. Most barges are not self-propelled and need to be moved by tugboats or towboats.
