Great Yarmouth's economy has long been influenced by activity at the river port, initially by the fishing industry when herring provided Great Yarmouth's main source of income in the late 1800's and early 1900's and for the past forty years as a base for the offshore support industry.
Norfolk's premier port, Eastport UK, is a modern, multipurpose facility with 24/7 unrestricted operations, integrating a well established river facility with a fully operational deepwater outer harbour with more than 1km of quayside, accepting vessels up to 220metres in length and up to 10.5metres draught at all states of tide.
The river port on the River Yare runs through the centre of Great Yarmouth. It has commercial berths along both banks for 2 miles from the river entrance and accepts vessels of up to 120 metres in length or up to 6.2 metres draught at high water springs.
For commercial shipping traffic there is ready access to all areas of port at all times of day or night, with no locks, bridges or tidal restrictions.
One of the largest groups of energy-related companies in England surrounds the port area in Great Yarmouth and inland. Businesses in the town provide an all encompassing service and support centre for the oil and gas industry, and also for wind farm developments.
