Early inland waterway transport used the rivers, and while barges could use sails to assist their passage when winds were favourable or the river was wide enough to allow tacking, in many cases this was not possible, and gangs of men were used to bow-haul the boats. As river banks were often privately owned, such teams worked their way along the river banks as best they could, but this was far from satisfactory. On British rivers such as the River Severn, the situation was improved by the creation of towing path companies in the late 1700s.
