Affects: UKHO Charts: 1183 and 1975 Imray Charts: C1 UKHO Small Craft Charts: 5607.3 Imray Leisure Folios: 2100.1. 2000.1 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- 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.

The second depth is identical as the earlier notice but I made a typo on the Longitude in Fisherman’s Gat. All corrected in the image!
