UKHO Permanent/Temporary/Preliminary Notices
1. ENGLAND - East Coast - Depths. Wreck. Drying heights. - Two new drying heights either side of the Barrow swatchway on the Barrow Sands (not a lot of water there) and a new wreck identified on the north side of the Barrow Deep. At 13.8m over the wreck unlikely to hinder leisure craft.
2. ENGLAND - East Coast - Depths. - One reductions of depth on the Sunk DW line to and from the Black Deep. This is a regularly check and has, for us, ample water and not where we ought to be.
3. ENGLAND - East Coast - Depths. - Six reductions on and around the Newarp Banks (off Winterton Ness). Unlikely to hinder leisure craft.

1. River Thames - Royal Naval College UAV Operations & Traffic Freezes - Commencing on Monday 8th July 2024 across 3 nights, a series of Unmanned Aerial Vehicle (UAV) - operations will be conducted outside the Royal Naval College Greenwich. To support these operations a
series of Traffic Freezes will be established and during these times, vessels will not be permitted to navigate in the area between the blue ‘traffic freeze’ lines on the chartlet, this will be managed by Local Traffic Control. Traffic Freezes will last no more than 15-minutes. Local Traffic Control will be undertaken from a PLA Harbour Service Launch exhibiting a blue flashing light, as detailed in the table which you can download at: Notices to Mariners Local List. Freezes are taking place tonight at 2345, tomorrow at 0400 and 2345, Wednesday at 0100 and 2245 and 2330. All vessels intending to navigate Greenwich Reach are to call the PLA Harbour Service Launch callsign ‘THAMES PATROL’ on VHF Channel 14 as follows:
Inbound at Lovells Wharf.
Outbound at Greenwich Ship Tier.
Prior to leaving a berth or mooring between Lovells Wharf and Greenwich Ship Tier.
Mariners may experience delays to their passage of no more than 15-minutes and the PLA will endeavour to ensure disruption to port operations are kept to a minimum. Owners and operators are reminded that no vessels other than emergency service vessels responding to an
incident are permitted to pass through the traffic freeze. All vessels are to maintain a continuous watch on VHF Channel 14, following instructions from the attending Harbour Service Launches. Further information will be broadcast by London VTS on VHF Channel 14
2. Approaches to Sheerness – Grain Spit - Diving Operations and Cable Laying Works - as part of the ongoing Neuconnect Interconnector project, diving operations and associated cable laying activities will be taking place on Grain Spit. Work to connect a subsea power cable to a pre-installed HDD entry point on Grain Spit is expected to commence on or around 9th July 2024 with completion expected by 4th August 2024. The dive team will primarily be working from a “Linkflote” pontoon which will be positioned at numerous points along the cable route which runs out in a NE’ly direction from Grain Spit and across the Swatchway. Divers may also need to utilise the craft “Celtic Guardian” if diving is not possible from the pontoon, further safety and survey craft will also be in attendance whilst work is underway. All craft will maintain a listening watch on VHF Channel 74 whilst at the worksite, all vessels transiting the Swatchway to and from the Thames are requested to keep well clear, pass with extreme caution and reduce speed/wash appropriately. Chartlet available as above.
3. Blakeney Harbour Association have made SEVERAL changes to the Aids to Navigation in Blakeney Harbour.
**** SOUTH CARDINAL **** A South Cardinal Marker has been installed at the southern tip of Blakeney Point. It is imperative that all vessels keep south of the Cardinal marker because the submerged section of the point is incredibly shallow.
The coordinates for the South Cardinal Marker are: 52°58.091'N 0°57.477’E. The light sequence for the South Cardinal Marker is: Q(6) + LFL 15s.
**** CHANNEL AROUND POINT **** The main channel has moved south of the point around the old mussel beds. This table lists the lateral marker positions that have changed. This Google Maps image of the tip of Blakeney Point demonstrates the new channel location and the South Cardinal Marker position.
**** OUTER HARBOUR LATERAL MARKERS**** The Lateral Markers have been relocated according to changes to the channel. This work is still under way and a further update will be sent as soon as there is suitable weather to continue to relocate the lateral markers.
No. 9 Starboard Green spar mark. Light sequence Fl.G(2.5s) has moved North west to: 52°58.822'N 0°57.538'E
No. 11 Starboard small cone mark. No light has moved North to: 52°58.732'N 0°57.419'E KEEP TO THE STARBOARD SIDE OF THE CHANNEL BETWEEN MARKERS 9 AND 11 UNITIL FURTHER NOTICE
No 10 still needs to be moved north west away from the west end of the point, this will be carried out ASAP weather permitting.
No.10 Port spar marker. Light sequence QFL.R Creates a gate with no. 9. Current lat and long: 52° 58.732’ N 000° 57.552’ E DO NOT PASS CLOSE TO NO.10 UNTIL FURTHER NOTICE
No. 3 Starboard needs to be moves south due to a sand bank forming between no. 1 and no. 3. This will be carried out ASAP weather permitting. DO NOT PASS CLOSE TO NO.3 UNTIL FURTHER NOTICE
No.3 Starboard spar mark. Light sequence Fl.G(2.5s) Current Lat and Long: 52° 58.841’ N 000° 58.106’ E
That's it tonight.
