River Crouch Survey Findings

The Port of London Authority have on behalf of the CHA recently undertaken Survey Operations on the River Crouch and Approach in areas of particular interest to deeper draught vessel as follows:

• In the vicinity of the Swallowtail West Cardinal Light Buoy
• Between Buxey No 1 Southerly Cardinal Light Buoy and Buxey No 2 Northerly Cardinal Light Buoy
• In the vicinity of the Crouch Northerly Cardinal Light Buoy

This information is available to view on the links below. It will further be incorporated in a new addition of Admiralty Chart 3750 [Rivers Crouch and Roach] scheduled for publication within the next few months by the UK Hydrographic Office [UKHO].

A further survey of the Raysand Channel has been commissioned for later this year.

The CHA will promulgate these findings and any alterations [if necessary] to the buoyage once completed. However, until then we would remind mariners of NTM No 43 of 2021 less water reported and re-emphasis that caution should be taken when using this route.

NTM No 43 of 2021

Raysand Channel

Mariners are advised that there have been reports of less water than charted between the RAYSAND and RAYSAND MIDDLE navigation marks.

We therefore advise that extreme caution be deployed if you intend to cross to or from the river Blackwater using this route and in all circumstances, it is strongly recommended that passage should only be made on a rising (flood) tide.
