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.

I caused this five reductions of depth in the Mersea Quarters and entrance to Tollesbury Creek following a survey in the autumn last year.  Local buoyage has been lifted and will be changed shortly.

Mersea Spit has changed shape and local fishermen reporting touching bottom at the bottom of LW springs.  It is now NOT possible to expect 2m CD throughout the Quarters.

The image is based upon the current Imray chart and can be downloaded.  But I would recommending that my CTTE images are used.  Again the current (as at Week 4) shows the old local buoyage but this will be altered (and announced) as soon as it is laid.

UKHO Chart: 1183

UKHO Leisure Folio: 5607.3

This is a late ‘catch-up’ on the buoyage changes in the Whitaker and Swallowtail channels from July, 2011.  (yes, I did mean July, 2011).  Chart 1183 is not one probably used by Leisure Craft being the whole Thames Estuary and it deals with the changes by deletion of the old marks and insertion of a legend saying the channel is ‘buoyed’.

I am aware that the Imray chart (2000.8, included in Imray/Meridian ID10) was correctly printed and republished in August, 2011 – DO NOT TRY TO APPLY THIS CORRECTION TO THAT CHART – although it would apply to earlier versions.

The UKHO Leisure Folio 5607.3 was republished in December, 2011 (9th Edition) and similarly will not need emendation although the 8th Edition will.

CTTE ‘diagram’ of the revised buoyage is available below.
