The South-West Sunk swatchway


Revised 8th May, 2019

PDF  Download

The SW Sunk was re-surveyed on 6th May, 2019..  The swatchway has migrated again a little to the north-east and consequently any previous chartlet is no longer accurate and should NOT be used.  Chartlet 'SW Sunk Swatchway 2019, V1' is the current chartlet.  

The preparation of the chartlet was kindly provided tide data from the Port of London Authority which assisted in reduction  to Chart Datum.

Note: As in 2016, I am recommending three waypoints and in consequence of the slight migration to the north-east, the  waypoints are revised for 2019.  Details are provided on the chartlet.  To the north-east, the Middle Sunk knoll is a quite gentle slope up.  However, the knoll to the south-west has a very steep edge and should be avoided.  Holding the rhumbline between the West and Mid waypoints is important.

I have now added the computer generated image on the left in the pdf download

The Little Sunk

Adjacent to the Barrow No 2 PHB

New September 2019

PDF  Download

This is a CTTE chartlet based upon a survey completed on 24th August, 2019.  This is usually a stable  crossing place and  it remains so.  The survey was more comprehensive  than previously and consequently there is a significantly greater amount of detail.

The image can be downloaded by itself or, by using, the PDF download you will received some general notes about observations and for those with copies of the book some observations about the waypoints and routes..

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.

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 2019.jpg

Bradwell Creek

Revised 2019

PDF  Download

Data on depths in Bradwell Creek.  This chart is from soundings taken in September and October, 2010 and  a re-surveyed 19.07.2011.  On 22.07.2011 six new withies were put into place on the eastern edge of Pewit Island and the red cans adjusted and these are now included in this latest version.  NOTE:  I have not had the opportunity to resurvey Bradwell but in frequent visits I check and it seems to me that the creek has largely remained as in 2011 with the exception that the shallow ‘bar’ now extends from half way between the first and second red cans as far as the third red can.  This ‘shallowing’ does, however, appear to be soft mud - TG was able to power through it.

In 2019, small lighting has been added: to the first red can, one the first existing withy , the green cone and on the posts at the entrance of the marina.  Apparently more lighting will be added.
