UKHO Permanent/Temporary/Preliminary Notices:
1. ENGLAND - South East Coast - Depths. Drying height. - Two reductions of depth in the Outer Harbour of Ramsgate, one reduction east side within the harbour and a ‘worsening’ drying height at the entrance to the Royal Harbour. There is also a warning in the Local List below.
2. FRANCE - North Coast - NM Block. - A UKHO block for the approaches to Boulogne.
3. ENGLAND - East Coast - Pilot boarding places. - Port of Great Yarmouth (ABP Ports) have changed the designation of their three Pilot Boarding Places and have added a fourth Pilot Boarding Place designated ‘Cockle’ (off-shore from Winterton). The change of names are: ‘Great Yarmouth Inner’ to ‘Outer Harbour’, ‘Great Yarmouth River Port’ to ‘River’ and ‘Great Yarmouth and Lowestoft Outer’ are changed to ‘Hom (Great Yarmouth and Lowestoft’.
4. ENGLAND - East Coast - Depths. - One reduction of depth on the Sunk DW channel east of the Sunk Inner mark. This is part of the constant monitoring of depths by the PLA and in consequence unlikely to hinder leisure craft as regards to the depth.
5. ENGLAND - East Coast - Depths. - Five reductions of depth, two on the north side of the Outer Harbour entrance of Great Yarmouth and three inside the Outer Harbour (south side). Not that where we are supposed to be!
Local - the usual NY flood of NtMs!

9. River Orwell - Oceanographic buoy (!) deployments - between Wednesday 14th and Thursday 15th January 2026, an Oceanographic buoy will be deployed in position 52° 00.23856' N 01° 12.77078' E in 4.4m CD (adjacent to Grog SHB (I have added an image showing the location) This will be clear of the main channel and will be marked by a yellow marker buoy.

12. Ramsgate Outer Harbour - Port Turning Circle Entrance Soundings - following recent strong Northerly storms, the accuracy and reliability of soundings at the Port Entrance are considered unreliable. These soundings were previously derived from the Hydrographic Survey of October 25. Vessels with a deep draught, specifically those drawing over 3.0 meters, should navigate the Port Entrance with particular caution, especially during periods of Low Water. To address this, the Port Authority is arranging an updated hydrographic survey for the affected area. Furthermore, dredging operations are being scheduled for both the Harbour and the Port Entrance to restore and maintain advertised depths. Further Notice will be issued when the new survey data is available and when dredging operations are due to commence.
