The Eastern Docks grew from a small beginning, in the eastern corner of the Admiralty Harbour. In the right angle made by the junction of the Eastern Arm with the shore a, roughly square, area of the harbour, known as the Camber, was enclosed by the West Jetty, jutting out from the shore, and the South Jetty, built out from the Eastern Arm. During World War I the Camber was used to accommodate the Dover submarine flotilla and their depot ship, HMS Arrogant. After the war the Admiralty broke-up obsolete naval vessels at their dockyard and in the Camber, before withdrawing completely by 1925. After the Admiralty's withdrawal a private ship-breaking business started up in the Camber. From the late 1920s Captain Townsend started to operate his car ferry service from the Camber, thus starting the trade which was to build the Eastern Docks into what it is today. During World War II the Camber became home to motor torpedo and motor gunboats of the Royal Navy.After the war the ship-breaking business returned to the Camber. The old Admiralty oil depot was taken over in two parts, one by Esso and one by Shell-Mex and cargo ships docked at the Eastern Arm. Townsend car ferries resumed operation and in 1951 designed their own linkspan at Calais, which allowed cars to drive off the ferry in France even though they were loaded by crane in England. In 1953, when 117,000 vehicles a year were using the port, a new car ferry terminal was opened allowing roll-on, roll-off traffic to start. The ever-increasing demand soon rendered the two berths inadequate and extra capacity and new terminal building opened in 1970. The first Hoverport opened here in 1968 before moving to its new location at the Western Docks in 1978. There are now six roll-on roll-off berths and one catamaran berth, and the Cargo Terminal on the Eastern Arm can accommodate ships of up to 300 metres in length.
