3. Surveyed Depths – Harwich Harbour – Update 7 - the latest hydrographic surveys showing depths in Harwich Harbour. The controlling depth for deep draught vessels navigating within the harbour area should currently be taken as 15.5m below chart datum, plus height of tide. Significant depths below chart datum (not including inside berth boxes) are:
• 15.0m - spot soundings between the Shotley Spit Buoy and Grisle Buoy
• 15.5m - spot soundings between the Grisle Buoy and North West Beach Buoy
See survey chart extracts via the download bujtton on the above quoted web page on the Local List for further information. Please note the grey shaded areas are for internal use purposes only and are not contour lines. Contact Harwich VTS or Haven Pilots for further information regarding tidal windows. This notice replaces local notice to mariners No. 38 of 2025, which is now withdrawn.
4. Dredging Operations – Jean T -tug Jean T (Callsign: MVS06) will be undertaking plough dredging operations from around 22 April 2025 for approx. 5 days, in the following locations:

5. Crouch Harbour Authority - Increase in River Swimmers, Inflatable and Personal Watercrafts - INFORMATION
With the onset of the sailing season, the volume of river swimmers, people using inflatable canoes, paddle boards and personal watercraft is expected to rise within the CHA District and in particular on the upper reaches of the River Crouch.
Regrettably, many taking up these sports for the first time are inexperienced, particularly in tidal waters and are not familiar with robust safety, seamanship, and good manners in not compromising other river users and staying close in toward the riverbanks.
The fact that you can enter the water from any part of an accessible sea wall and does not require more formal launching arrangements makes the policing of those taking part in these activities extremely difficult.
To ensure that the waters are a safe and enjoyable place for all leisure pursuits, we respectfully ask that all river users keep a good look out at all times, report any cases of near misses, poor behaviour and disregard of others to the Harbour Office providing as much detail as possible.
It is further recommended that if Clubs are not already doing so that they include a section within their event risk assessments to cover this matter.
Your cooperation is appreciated, thank you
6. Crouch Harbour Authority - Areas of High Density Small Sailing Vessels - SAFETY/NAVIGATION
Owners and operators of power-driven vessels navigating in areas of high-density small sailing craft, in particular but not restricted to, the Burnham area, the upper reaches of the River Crouch between Brandy Hole and Hayes Farm are requested to do so at a slow speed, in a considerate manner, whilst keeping a sharp lookout at all times.
The Up River Yacht Club, South Woodham Ferrers, and Eyott Sailing Clubs (launching from Hullbridge, South Woodham Ferrers and Fenn Creek) host and run well organised regular sailing events, with marshalling and safety boats in attendance at all times.
However, it should be borne in mind that some club members participating are both young, relatively inexperienced, and undergoing training.
The Crouch Harbour Authority therefore respectfully request that those in charge of power-driven vessels navigating in these waters are especially vigilant and cautious.
Organisers of all events taking place within the CHA District should, when considering their race courses, be mindful of designated fairways and restrictions of commercial and larger power-driven vessels constrained by their draught, and ability to manoeuvre, and ensure that their passage is not impeded.
7. Rowhedge Pontoon - Gladys reports the new pontoon in place.
8. NeuConnect Interconnector - UK Pre-Sweeping - This kindly reported by Brightlinsea Harbour Master and Team. - NeuConnect is a new high voltage direct current (HVDC) electricity transmission interconnector between the Isle of Grain, Kent, mainland UK, and Wilhelmshaven, Germany, routed through UK territorial waters (TW) and exclusive economic zone (EEZ). Prysmian PowerLink (PPL) has been contracted to install the submarine cable. Pre-sweeping activities will be taking place along the NeuConnect cable route. Works will be undertaken by Pre-Sweeping subcontractor Rohde Nielsen.
The planned operations will be conducted by the vessels:
Njord R (TSHD)
Ask R (TSHD)
USS 202 (ROUV survey vessel)
Mobilisation of the Njord R, Ask R and USS 202 is anticipated from 24 April 2025 on site to commence pre-sweeping activities from 28 April 2025 onwards. The full scope of works are anticipated to take 5-6 months (weather dependent). Work is carried out from KP 78.9 (51º 48.2’ N 01º 38.0’ E) to KP 199.1 (52º 23.6’ N 02º 45.9’ E). Pre-sweeping activities between KP 78.9 to KP 145 are anticipated to be completed between 28 of Apr and beginning of June (weather dependent, it can take longer).
Mariners are reminded to navigate with caution and keep a continuous watch on VHF when navigating in and around the operational areas. Port of London VHF working channel is Ch. 69. Port of Medway VHF working channel is Ch.74. All vessels involved in operational activities will exhibit appropriate lights and day-time shapes prescribed by the International Regulations for Preventing Collisions at Sea, relative to operations. The vessel will also transmit an Automatic Identification System (AIS) message. Safety Zones - During cable installation a 'rolling' 500m safety zone will be applied around all installation vessels and activities. NOTE: the route is from the Isle of Grain, along the south side of the Knock John and Black Deep Channel, through the Sunk Precautionary zone onto international waters. Note we need permission from the PLA (VHF Ch 69) to cross or use the Black Deep Channel so be aware of those vessels working there at a time that coincides with you. The Notice is long so you can download it from the Local List of the above quoted web page. Images, route, time (not the easiest). One vessel is one of those automated vessels, small and very LOW! But it will be squawking AIS (one hopes).
9. and 10. London Array Wind Farm - Two jack up vessels coming to work from 15/05/2025 for a 4 week period. and 01/06/2025 for a 10 day period. Equipment will be periodically deployed and suspended from the vessel crane during jack up operations.
A 500m radius restricted zone will be in place, centred on the Ziton Wind Server whilst pinned on location. If access is required to this zone for non-project vessel traffic, authorisation must be requested from the vessel master.
That is it.
