About

Heybridge Basin's famous sea lock links the Chelmer & Blackwater Navigation to the Blackwater Estuary and would once have enabled smaller boats to enter and exit the canal and travel around the coastline. Today it is can still be used by suitable vessels (when the tide is right), but only if the skipper has been trained by Essex Waterways and has a special key! Is a scenic spot to have a picnic or enjoy lunch in one of the nearby pubs.

Heybridge Basin Sea Lock was built as the eastern terminus for the Chelmer & Blackwater Navigation, and the village of Heybridge Basin grew up around it, as there was plenty of work unloading the ships into the barges that took supplies to Chelmsford. The Basin was built in 1796 and the canal opened on 3 June 1797 on land bought from the Dean & Chapter of St Paul’s.The bridges & locks were designed by the engineer, John Rennie FRSE (1761-1821) who was responsible for the design of many maritime buildings including lighthouses.

By the end of the 19th century the canal trade was in decline due to competition from the railways. Although the sea lock was enlarged to take European timber ships shortly after the World War 2, it could not halt the decline and finally commercial activity ceased in 1972. However, today the area is thriving with houseboats, pleasure boats and cruises along the navigation.
