Note: Former Notice 1319(T)/23 is cancelled.


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.

Three reductions of depth on the eastern edge of the Whitaker Spit and four around the ‘finger’ extending north-east from the East Barrow Sand.  Cutting across Whitaker Spit to and from the Middle Deep perhaps needs a little more care.  These changes were prompted by a Port of London Authority survey earlier this year commissioned by the Crouch Harbour Authority.   It seems to me the PLA survey on the north-east corner of the East Barrow Sands was deliberately to help leisure users who like to 'cut the corner' round the edge of the sands dropping down to the SW Sunk.

Eleven reductions of depth on the Colne: two in Brightlingsea (both ‘edge’ issues), three on the way up to Rowhedge (one of which is a shallow patch between No 26 and No 28 [0.1m CD} on the way to the Barrier), and 5 at Rowhedge and above.  Of the latter, one on the way up to the Colchester Quays is a new drying height of 3.5m!  At that spot was 0.1/0.2 previously so one wonders what caused an eleven foot ‘hump’!

A ‘Less water reported (2021)’ notice for the Ray Sand following the local NtM from the Crouch Harbour Authority last week.  The notice is more about correcting the chart than changes this year.  As I reported last year, the worst water was in line with the Ray Sand buoys and best water is about on a north – south line between 000°59’600E and 001°00’00E.  This year’s survey in September confirmed that idea (see at the Download page).

The creation of two Oyster Spat Trays in Brightlingsea were notified in Week 29 and was included in the Temporary List in Week 29.  UKHO are now adding this Temporary list.  I cannot make sense for the first position as this marks the ‘buoy’ (a huge exaggeration of a description) close to but ‘outside’ the Tide Gauge at Brightlingsea and just in the channel.  However, having actually seen the ‘buoy’, it is ‘out of the way’ in both the sense that it is Brightlingsea side of the Gauge and outside of the entrance channel.


I could make no sense of the positions quoted in the Temporary notice so probably UKHO have been supplied with slightly incorrect lat/long.

Five unmarked seabed and six marked measuring instruments in and around the Blackwater.  This is in connection with the research for the new Nuclear Power Station.  I would suggest any user of the Blackwater should take note or the unmarked seabed instruments.  Tacking across the Blackwater mid-tide is running the risk of hitting one such instrument, another when going through Thirstlet Creek and the stumble.  The three on Dengie are, perhaps, safely closer to the shore for people using the Ray Sand (the 1 degree meridian is the best option).  But don’t tack down towards the edge of Sales Point (but there has also been warning of an obstn off Sales Point).

This is correcting the chart position of the Ray Sand Middle at the Ray Sand.  The buoy has never been moved (apart when it goes walkies) but the annotation had never caught up with the ‘official’ position.  Now I may be a little mystified and may have confused myself!  When I did three surveys in July last year (2019), the position of the Ray Sand Middle was (in my view) 51° 40´·00N., 0° 59´·50E.  But when the Crouch Harbour Authority reported that the Middle SWM went off station on October they quoted the position FROM which it moved as 51° 40´·00N., 0° 59´·00E – which in my view where it had been.  I guess an early trip in May?  The relevance I would suggest is that the 0° 59´·00E meridian has the highest drying height on the Ray Sand just south of the now quoted position.  See my download page for the latest chartlet.
