Langstone Harbour is the centre of three linked harbours on Hampshire’s southeast coast, with Portsmouth Harbour to the west and Chichester Harbour to the east. The Harbour is important for its environmental designations. Commercial shipping, fishing and recreational boating have been supported in the Harbour for many years.
The Harbour is a haven for charter fishing boats and commercial fishermen. Recreational activities such as yachting, dinghy sailing, motor cruising, wind-surfing, water skiing (under license), jet skiing (with a permit) and canoeing are all well established. Please remember the Harbour speed limit is 10 knots.
Together with Chichester Harbour, which lies to the east of Hayling Island it is designated as a Special Protection Area for wildlife. West of Portsea Island is Portsmouth Harbour and the three linked harbours are important recreational and conservation areas as well as supporting commercial fishing and shipping. The statutory Harbour authority for Langstone Harbour is the Langstone Harbour Board.
The eastern boundary with Chichester Harbour is defined by the old Hayling Island railway bridge (now in ruins). Just east of this runs the modern Hayling Island road bridge, and just east of that runs an historic causeway known as the wade way, which was originally the only crossing between Hayling Island and the mainland. The wade way is now impassible, having been cut in two by a deep channel for the Portsmouth and Arundel Canal in the 1820s
The western limit of the Harbour coincides with the railway bridge over Hilsea Creek. The Naval Dockyard Port of Portsmouth has jurisdiction to the west of the railway bridge.
