Three new reduced depths for SNC 2692 at the Long Sand Head.  A new edition of SNC 2692 was only issued on 28th March!  The reduced depths indicate that the Long Sand Head continues the common trend to extend to the NE.  I understand it is likely the Long Sand Head North Cardinal which is critical marking the tight corner in the two-way TSS will be moved in due course.  The image includes 3 other reduced depths in that area that were reported earlier in NtM 1378 in Week 13.

Nine reductions of depth at the Mouse channel side of the SW Barrow knoll.  If you are a ‘corner cutter’ round the knoll (e.g. to or from the Princes Channel into the West Swin) it is worth seeing the image.  Note the edge of that sand is pretty ‘steep-too’ and the tail has shallowed.  Also if you saw NtM 638 earlier this year you will see that the depth almost exactly there has reduced from 4m to 2.7m in a matter of months.

Four reductions of depth on the Little Sunk, two of which are on the usual crossing point and two indicating a slight growth of the Little Sunk knoll.  This change is caused by our 2023 survey and the crossing point is NOT significantly affected.  At the moment the growth of the Little Sunk appears to be quite slow, indeed the worse depth of 0.7m looked like the ‘crest’ of a sand wave.

This notice is including two new drying heights and a deletion of a wreck that were reported in NtM 1798 in Week 22.  These new drying heights are both on the Long Sand and are included to update two UKHO small craft charts.  I am repeating what I said in week 22:  “Three new drying areas around the Black Deep: one on Long Sand at the edge of the Black Deep No 6 port hand buoy, a second, a drying area, on the Long Sand near the Black Deep No 4 close to the old Beacon, the third, again on the Long Sand where a wreck was once marked at 3.2m.

On the Little Sunk a depth is reduced to 0.9m which formerly was marked close by as 1.8m.  That does not affect the Little Sunk ‘crossing’ but suggests it is worth a re-survey which we will do at the second opportunity.”

Three new drying areas around the Black Deep: one on Long Sand at the edge of the Black Deep No 6 port hand buoy, a second, a drying area, on the Long Sand near the Black Deep No 4 close to the old Beacon, the third, again on the Long Sand where a wreck was once marked at 3.2m.

On the Little Sunk a depth is reduced to 0.9m which formerly was marked close by as 1.8m.  That does not affect the Little Sunk ‘crossing’ but suggests it is worth a re-survey.

Finally there is a tiny reduction of 0.1m in the centre of the Black Deep deep water channel.

The secondary channels have a minimum depth of 9m and vessels which can safely navigate outside of the main Knock John Channel should us it rather than the established Channel.  Note that the northern side of the Knock John are for inbound vessels and the southern side for outbound vessels.

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.

This Notice is to amend two UKHO Small Craft Charts in the middle of the Thames Estuary.  The Standard Nautical Charts have been amended vide Notices 4891/2021 (regarding Foulger’s Gat) and 5173/2021 (regarding the Middle Sunk).  Note that I am currently  recommending that crossing at the Middle Sunk is only used with great caution as there has only been partially surveyed by the Port of London Authority and us (CTTE).  Navionics and C-Map have adopted these changes (earlier this year) but would be only brought up to date if you have a current subscription.  Old versions would be still be optimistic!  The second image is using the UKHO block that was issued by NtM 5173/2021 which incorporates all the changes on the Middle Sunk.  Note that the block is intended for the SNC not the SCC but for practical purposes it would serve.

This notice listed five new drying heights and two reduced soundings at the Middle Sunk (between the Barrow and Black Deeps).  Chart 1183 needs individual annotation; Chart 1975 has a UKHO block (illustrated).  This notice is the consequence of a 2015 Port of London Authority and an exploratory survey by CTTE.  The result significantly updates the Middle Sunk crossing which shows a series of drying ‘knuckles’ on the ‘finger’ that extends north-east from the Middle Sunk knoll.  With the SW Sunk and Little Sunk crossings both viable, I would suggest that the Middle Sunk crossing ought not be used without some careful consideration.

The UKHO block also includes part of the SW Sunk swatchway.  Current paper and electronic charts have not been updated since 2019 and they are therefore 600m out of position.  You will see from the image taken of the UKHO block placed on Chart 1975, you will that it appears that the SW Sunk swatch is now recorded in the right place in the primary database.  I am checking that the record has been updated and I will report back.
