Four revised reduced depths over wrecks, six reduced depths and on new wreck and one new obstruction in the Wallet and on the Gunfleet Sands.  There is a general trend of reduced depths on the NE tail of the Gunfleet Sands, indeed earlier this year a UK block was issued vide NtM 3694/24 in week 32.  The block is slightly amended by this notice.  There have been several notices of other reductions of depths so the image incorporates all the changes reported.  Two images.

This is a preliminary notice following the recent Civil Hydrology survey reporting reduced depths around the Gunfleet Sands, Sunk Sand and in the Kings Channel.  These comprise 1. 4 reductions of depth, 3 adjacent to the Gunfleet Spit cardinal buoy and a fourth with ample water for use north of the cardinal buoy: 2.  2 reductions at the Sunk Head and a third close to the Middle Sunk: 3. A single reduction in the Kings Channel (or West Swin) with ample water for us.  There had been a Notice earlier this year (NtM 1026) which advised four reduced depths on the Little Sunk following our survey so those are included in the image.  UKHO plan to issue a new edition of SN chart 1975 early next year incorporating all the changes that have been reported this year.  That SNC is the leading chart for electronic chartmakers to follow.

This notice provides a warning of ‘Less water reported 2024’ at the Knoll.  This was caused by us when we were down there on a rough day – hence no precise depths but our view was that south of the NW Knoll PHB had almost no water at chart datum.  On Saturday we conducted a very full survey in ideal conditions but regretfully (and frustratingly) we (I) suffered a major computer crash just after the survey where we lost the majority of the data.  We are endeavouring to reinstate the data but it is unlikely.  However, it was clear to us that a large area of sand is barely awash so stay clear.  The Knoll swatchway does still exist.

This Notice is catching up with the changes of buoyage at the Ray Sand which occurred in 2023 as a result of surveys.  The previous two Safe Water Buoys – the Raysand North and Raysand Middle are removed completely.  A new unlit yellow buoy – The Raysand North is placed quite well to the East and the unlit round yellow Ray Sand buoy is moved to match the same longitude meridian.  There is a CTTE download at  on the Download page which provides the detailed chartlet with has had the correct buoyage since July last year.  By all means use the free download.  Use the 1° meridian to find the best water north of the Ray Sand between the River Blackwater and the Ray Sand.  There are plans for a new edition of UKHO Chart 1975 Thames Estuary – Northern Part in the summer this year which should bring the contours up to date.  As of today Navionics have placed the Ray Sand in the right place, have deleted the Raysand Middle, kept the Safe Water coloured Raysand North in the (wrong) old position and the Buxey Beacon in the wrong position.   It tends to be handy to know where you are if you use Navionics.  C-Map is up-to-date as regards the buoys.  The northern contour of the Ray Sand is as my chartlet.

There is a new UKHO block covering the west tail of the Swallowtail and the Whitaker Channel of the Crouch around the Sunken Buxey.  The new depths are courtesy of a Port of London Authority survey last year.  The block is for the full SNC UKHO chart and there are a series of 6 depth changes and a new obstn for the SCC charts (which doesn’t get a new block).  In case you want to plot the individual changes I have marked up the changes using the jpg image.  If you click on the jpg you can download it.  Also, of course, you can download the UKHO block as a pdf via the button.  Note that out of view of the UKHO block there is a new depth close west of the Crouch NCB.  

Note also the UKHO block incorporates the removal of that yellow special mark just north of the Sunken Buxey and the re-positioning of the Swallowtail W cardinal.
