Model. Vesels of this type were formerly in common use on the rivers Humber, Trent and Ouse and on the canals connecting them. They were carvel-built vesels of great strength, being mainly of oak and having unusually heavy timbers. They usually carried coal, bricks, and sand as cargo. They were handled by a man and a boy. Usually they were about 60 ft long with a beam of 15 ft and were capable of carrying 90-100 tons.
