Buoy changes at the Long Sand Head

NEW April 2024

PDF  Download

Trinity House have issued a Notice to Mariners on 17th April, 2024 providing us advance notice of changes at the Long Sand Head.  The changes are planned to be actioned “on or around 17th May, 2024”.  In the past 12 months, the Long Sand Head has continued gently, but persistently, to creep more to the northeast.  For us there is no crisis but heed the warning not to ‘cut the corner’.  For shipping using the Two-Way Route in and out of the Black Deep two changes have been necessary.

The changes are:

The creation of a new east cardinal buoy.  This will be positioned very close to current position of the Longsand Head north cardinal buoy.  The new buoy will be designated ‘East Longsand Head’.  Characteristics are shown in the chartlet.  Note it will have AIS.

The Longsand Head north cardinal buoy will be moved west and a little north.  As you will see in the chartlet the effect is to make the corner clear for shipping. Characteristics for this buoy will remain as at present.

The South-West Sunk swatchway


Revised 26th November, 2023


PDF  Download

See the 2021 video showing the tide rip.  Note, if you follow the recommended wpts, you will be well clear and probably would be not be there at that state of the tide anyway.

Initially this year the SW Sunk was surveyed on  21st June, 2023.   That found part of a wreck on the north side of the swatchway.  The Port of London Authority re-surveyed the swatch at the end of August  and they kindly forwarded all the data to us.

The results are that the 'new' wreck has 2.6m CD over it, the part exposed is 1.8m above the level of the seabed and there is a scour of 8.9m to the south of it.  It is clearly marked.

More generally, the SW knoll is stable - that is it has not moved significantly - but the SW side of the Middle Sand has retreated thus providing us a wider swatchway - which is good news.

The existing waypoints remain fine.

The chartlet is created courtesy of the full Port of London Authority data.

The revised Outer Crouch buoyage July 2022


Revised 15th June, 2021 and then18th July, 2022

NEW 2022

PDF  Download

Following the annual maintenance round, the Crouch Harbour Authority has altered the buoyage in the Swallowtail and Whitaker channels in June, 2021.  Effectively the overall arrangement for the buoyage remains as before except that three buoys have been withdrawn and some positions, light characteristics and names have been amended.

Subsequently, following a survey by the Port of London Authority, the CHA has moved the Swallowtail W to the west.

All moves incorporated in the chartlet

Extended chartlet (east side)

We completed two surveys in August and September and the new chartlet has available. However, 0n 13th July, the Crouch Harbour Authority notified changes to the Ray Sand buoyage.

The Ray Sand buoy is re-located at 51.39'.84N, 001.00'.57E and the Ray Sand North (the Ray North) buoy is changed to an unlighted Yellow  Special Mark Pillar Buoy at 51.40'.81N, 001.00'.57E.

The chartlet has been changed to reflect the buoyage.

The Little Sunk

NEW 2023

Surveyed on 10th July, 2023

PDF  Download

This is a CTTE chartlet based upon a survey conducted on 10th July, 2023.  The Little Sunk (discussed on Page 24, 3rd Edition) is is usually a stable  crossing place and  it remains so in 2023.  Arguably it has lost 0.2m of depth but it has a controlling depth of 3.2m in the centre.

The crossing area is bounded by two wrecks to the south-west and the wreckage of the old 'Little Sunk' Beacon to the north-east.  All hazards are physically unmarked but there is ample room assuming a valid GPS signal over sand.

While we were ‘criss-crossing’ over the Little Sunk I took the image of Foulger’s Gat.  Images of Foulger’s Gat at water level is quite difficult.  Close-to the Gat cannot be fully included, if it can be included, the camera is too far away.

For this image (and the technical), the camera is on the Little Sunk and was 3.067nM from the Long Sand Inner Safe Water Buoy, bearing 175°(T), Turbines A12 is 6.742nM from the camera.  Obvious the Long Sand Middle could not be visible.  The camera was pointed at 174°(T).

Quarters Drawing 2019 Buoyage revision Mersea and Tollesbury Routes V2.jpg

Mersea Quarters

Buoyage as August, 2019

(Tollesbury No 4 now placed back)

PDF  Download

This is a CTTE chartlet based upon a survey completed during October, 2016.

Changes to depth across the Quarters has required a change to the buoyage which was re-laid in April, 2017.

Deep draught yachts (i.e. @2m draught) is recommended to follow the suggested route at LWS. Note this has been amended this month (May) to show the 'Obstn' SW of the Nass Beacon is not now annotated as ED.  It DOES exist and should be regarded as dangerous to leisure craft.

Bradwell 2020 all data compromise V3.jpg

Bradwell Creek

New chart 2020

PDF  Download

Re-surveyed on 21st July, 2020 and redrawn.

The chartlet is drawn to Chart Datum.

I have  just added a table of Tidal Height predictions at Bradwell Creek which I hope will assist new visitors.

When printed the chartlet is best in A3  size.  It is difficult to include all the detail in A4.  None is omitted so it will be quite small.  Of course as a PDF or JPG it can be enlarged as you wish.
