Affects UKHO Charts: 3741 Imray Charts: C1 UKHO Leisure Folios: 5607.9 Imray Leisure Folios: 2000.6, 2000.7. 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 Leisure Folio: 5607.3 This is a late ‘catch- 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.
