Wikipedia has a page about Thames and Medway Canal
The Thames and Medway Canal is a disused canal in Kent, south east England, also known as the Gravesend and Rochester Canal. It was originally some 11 km (6.8 mi) long and cut across the neck of the Hoo peninsula, linking the River Thames at Gravesend with the River Medway at Strood. The canal was first mooted in 1778 as a shortcut for military craft from Deptford and Woolwich Dockyards on the Thames to Chatham Dockyard on the Medway, avoiding the 74 km (46 mi) journey round the peninsula and through the Thames estuary. The canal was also intended to take commercial traffic between the two rivers.
