Notices to Mariners Week 32

Sorry late again, busy sailing!

UKHO Permanent/Temporary/Preliminary

1. Admiralty Charts to be published 20 August 2020 – Chart 2052 – England – East Coast, Orford Ness to The Naze. 1:50,000 – Includes changes to depths from the latest British Government surveys.
2. ENGLAND – East Coast – Legend. – New warning of obstructions off Mersea Island. This is an area direct in line with the Quarters and is often sailed. Note that in week 27 of 2019 an oyster laying further closer to the shore was established and was and is clearly marked. At present I do not know if this ‘warning’ is just associated with the marked area or whether new obstructions have been found. – Image on the usual page: Notices to Mariners
3. ENGLAND – East Coast – Obstruction. – 
A new obstruction in the Southern Secondary Yantlet Channel just west of the Sea Reach No 2. At 10.7m unlikely to hinder leisure craft and not where we ought to be! The additional sounding in the image is from NtM No 1505 earlier this year.
4. NETHERLANDS – Light. Fog signal. – Changes of the light and sound characteristics at the Goeree Light which is on the approaches to the Hook of Holland.
5. ENGLAND – East Coast – Marine farms. Buoyage. – The creation of two Oyster Spat Trays in Brightlingsea were notified in Week 29 and was included in the Temporary List in Week 29. UKHO are now adding this Temporary list. I cannot make sense for the first position as this marks the ‘buoy’ (a huge exaggeration of a description) close to but ‘outside’ the Tide Gauge at Brightlingsea and just in the channel. However, having actually seen the ‘buoy’, it is ‘inside’ in both the sense that it is on Brightlingsea side of the Gauge and outside of the entrance channel so out of the way. I could make no sense of the positions quoted in the Temporary notice so probably UKHO have been supplied with slightly incorrect lat/long.


1. LIMEHOUSE REACH – DUKE SHORE WHARF – TEMPORARY WORKS REMOVAL – This Notice replaces M13 of 2020 – On 18th May 2020 contractors commenced works on behalf of the Environment Agency to undertake the removal of the temporary structures at Duke Shore Wharf. The crane barge NEPTUNE will continue to be moored on spud legs and positioned outside the Authorised Channel. The chartlet (shown on the above quoted page in the Temporary List) depicts the location of the works and the limits of the navigation exclusion zone defined by the red boxed area. Only vessels engaged in the works may enter the exclusion zone. It is expected the works will take approximately another six weeks. Workboat DIVECO5 will be in attendance to support the marine operations, maintaining a listening watch to London VTS. London VTS will broadcast requests for vessels to “proceed with caution” or “proceed at slow speed”, as described in Permanent Notices to Mariners 4 of 2014 as required by the works. International Code Flags “Romeo Yankee” will be displayed when this is in effect. Further details will be broadcast by London VTS on VHF Channel 14.
2. Flagged Buoys Off Black Point, River Crouch – The Fishermen have now completed their operation at Black Point and the Buoys have been removed. – This Notice cancels local NTM No 29 of 2020.
3. Crouch – Update COVID 19 Restrictions – Recreational and Leisure Activities – As of 4th July 2020, there are now no UK Government restrictions SPECIFIC to boating. However, the UK Government COVID-19 Guidance on social distancing should still be observed. Mariners should be aware of their berth operator’s latest policies and stay alert and take all measures and precautions to prevent and minimise the potential spread of infection. At present the Harbour Office in Burnham remains closed to the public but open for business as usual by telephone and email. This Notice cancels local NTM No10 of 2020.
4. RIVER MEDWAY – SALTPAN REACH – LONDON THAMESPORT DIVING OPERATIONS – Diving operations are due to commence at London Thamesport Terminal in Saltpan Reach on the 27th & 28th July 2020.

Mariners are advised to slow down, pass with caution, make minimum wash and maintain a listening watch on VHF Channel 74. Dive Ops will be focussed around the following approximate position : 51°25.95 N – 000°41.28 E – Admiralty Chart No. 1834 refers.
