UKHO Permanent/Preliminary/Temporary Notices
1. FRANCE - North Coast - Depths. - Two reductions of depth on the southern side of the Binnen Ratel bank whch is one of the off-shore banks of Zeebruggee.
2. ENGLAND - East Coast - Legends. - Five new legends displaying dredged depths in the Ipswich Marina and Docks. All ample water for us of course.
3. ENGLAND - East Coast - Obstruction. Buoy. - A new ‘obstn’ in the Mouse Channel east of the SW Barrow west cardinal buoy and west of the ‘Alice’ danger buoy. Adjacent to the new ‘obstn’ are three unlit Orange buoys; all these close to an existing lit yellow special buoy.
4. ENGLAND - East Coast - Dolphin. Pontoon. Legend. - New dolphin installed instead of a former pontoon on the south bank of the River Thames in Long Reach east of the QEII bridge. Solely a commercial dolphin.
5. FRANCE - North Coast - Depths. Wreck. Drying contour. - Two reduction of depth in the English Channel, neither of which will hinder leisure craft, four reductions of depth on the Banc a la Ligne and La Barriere off Wissant west of Calais and a change of wreck designation east of the Colbart SW south cardinal buoy. Of two reductions in the Channel, one is in the NE running TSS, the other on the tail of the Ruytingen bank. Of the four reductions of depth ‘off Wissant’, two are shown as soundings, the third is a "circular limit of low water line". I admit needing to turn to ‘Symbols and Abbreviations’ for the ‘low water line level’ for the exact definition; that being the line of 0. Probably suggests trying to find a lee east of Gris Nez is not the best idea. The wreck east of the Colbart SW just in the TSS separation zone is now defined as an unsurveyed wreck over which the exact depth is unknown but is considered to have a safe clearance of 20m – so unlikely to hinder leisure craft. Note it is marked ‘PA’ i.e. positon approximate. Three images. (Note the images can be found at Notices to Mariners)

RIVER THAMES - LOWER HOPE REACH TO SEA REACH - RESEARCH EQUIPMENT DEPLOYMENTS - previously issued as L56-23 and has been reinstated. - on or about 11th December 2023, contractors instructed by the Environment Agency will undertake works to deploy 2 hydrodynamic monitoring devices, known as Acoustic Doppler Current Profilers (ADCPs), to the bed of the Thames in 2 separate locations. The deployment of the ADCP instruments will be undertaken from the vessel JENNY D and once deployed in their respective positions, will each be marked on the surface by a lit Special Mark with character Q Fl Y (5) 20s 0.3. The locations of the ADCP deployments can be seen in the chartlets on the above quoted webpage. Sites at Mucking Flats and vicinity of Shoeburyness.

The equipment and/or buoys may be serviced from time to time while deployed. During deployment and recovery, and any periodic servicing while deployed. Requirements to proceed with caution or at slow speed will be made in accordance with the procedure set out in the Port of London Authority’s Port Information Guide, under ‘London VTS’, ‘Section 4’.
