RIVER THAMES - To ensure safe navigation, mariners are kindly reminded of the importance of practicing good seamanship and exercising utmost caution when executing turns in the river. It is essential that vessels in the proximity of those performing turning manoeuvres also exhibit equal levels of caution and vigilance. A Vessel Turning Any vessel turning is required by Thames Byelaw 25.2 to ensure that the fairway is sufficiently clear for the manoeuvre so as not to endanger or impede any other vessel. Before commencing a turn, or instructing assisting tugs to manoeuvre, the mariner should ensure, by all available means, that there are no vessels which may be adversely affected by their movement. The sound signals prescribed in Thames Byelaw 42 should be used to indicate the vessel’s intentions. A Vessel Passing a Vessel Turning Notwithstanding the above, vessels intending to pass a vessel which is turning or about to turn should navigate with particular caution. They should be aware of the possible space required by a vessel turning, considering wind and tidal conditions. Assisting tugs may be using long tow lines resulting in a far larger swept path. Passing should be carried out at a safe distance and safe speed considering the effects of hydrodynamic interaction, wash and draw off. Traffic Management by London VTS When a reporting vessel is turning off a berth, London VTS may manage traffic. If any vessel wishes to overtake or pass a vessel once its turn has commenced, London VTS may agree that passing can take place in one of the following circumstances: The turn is complete to such an extent that the pilot or PEC holder informs VTS that they permit through traffic under VTS traffic management. The turn is taking place clear of the navigational channel.The passing/overtaking vessel has sufficient room to pass the opposite side of the channel, or in the secondary channel, with permission from London VTS. Any vessel intending to pass a reporting vessel which is turning, or about to turn, should make early contact with London VTS for instructions. |

RIVER THAMES - Following recent incidents involving vessels not taking appropriate action when passing speed reductions, specifically at King Edward Memorial Park, the PLA has identified a requirement to publish further guidance on adherence to speed reductions. Mariners are reminded of their obligations to reduce speed and wash, such as to be appropriate for the activities taking place, when a speed reduction is in force. While this guidance is framed for King Edward Memorial Park, it applies to all speed reductions on the tidal Thames. What is a speed reduction? “Speed Reduction” means a notification from London VTS that vessels must proceed at reduced speed through areas where activities sensitive to the effects of wash or draw- As a guide, speed reductions are used for hazardous activities such as diving, salvage, heavy lifting, working on the waterline from scaffolding or pontoon/small boat, and bunkering operations. Signals for Speed Reduction Notification Mariners will be notified of speed reductions by: 1. Romeo Yankee flags. The site, vessel or installation will display the international code flags “Romeo Yankee” by day and illuminated rigid replica by night. 2. VTS broadcasts. The speed reduction details, including location and activity requiring the speed reduction, will be identified in the half hourly navigational broadcast. Masters considerations in a Speed Reduction The Master must judge the speed appropriate to the circumstances, based upon the activity identified in the broadcast. Reduce speed in good time. Fully consider the vessels wash and draw off, especially when accelerating/decelerating. Remember the exact location of works within the site may not be visible, such as in the case of diving. Remain at appropriate speed until finally past and clear. King Edward Memorial Park King Edward Memorial Park is a Thames Tideway Tunnel works, where a number of hazardous activities have been and continue to take place; these predominantly include diving and heavy lifting. These activities may be taking place in any location across the works site when a speed reduction is broadcast. For this reason, regular speed reductions have and continue to be broadcast. Following an increase of substantiated complaints against vessels transiting this area, when a speed reduction is broadcast by London VTS and Romeo Yankee flags flown, Masters must reduce speed to such that they will not endanger the works through dangerous wash. As works may be taking place in any one or multiple locations across the site Masters should consider speed reductions in this area to apply across the area , and maintain a steady speed, as shown in the chartlet. Masters of high- Failure to comply with a speed reduction As speed reductions are granted to ensure the safe execution of hazardous activities any failure to comply may result in property damage, pollution, or even serious injury or death. For this reason, failure to reduce to an appropriate speed in good time and remain at such speed until finally past and clear will be taken seriously by the PLA. All incidents will be investigated and where noncompliance with the speed reduction is found, enforcement action will be taken. |

Please also consider and keep to a minimum your wake and wash when passing: • Through Burnham Fairway. • Essex Marina. • North Fambridge swing moorings. • All areas upriver of Brandy Hole. • Paglesham swing moorings – River Roach. Ministry of Defence (MOD) Shoeburyness: Range Sea Danger Area SAFETY We have been asked to publish the following safety information from QinetiQ for mariners to be aware of: With the summer months just around the corner, it’s timely to remind local sailing and watersports clubs of the restrictions in the vicinity of the Foulness and Maplin Sands. QinetiQ operates the live weapons test and evaluation Range in Shoeburyness and on Foulness Island in Essex, known as MOD Shoeburyness. The Range is active Monday to Friday (occasionally at weekends), all year round, conducting activities that involve firing and detonating live ammunition, often over long distances, out to sea. To enable the Range to work safely and ensure that hazardous activities do not present a risk to members of the public, it operates under the jurisdiction of the Artillery Ranges Byelaws 1936 and the Shoeburyness and District Military Lands Byelaws 1935 (under the Military Lands Acts 1892 to 1903). The byelaws govern the use of the land and rights of access and passage through the byelaw area. The byelaws cover an area of the Thames Estuary and the North Sea and the inner waterway that runs from Havengore Creek across to the River Roach and the River Crouch. These areas are known collectively as the Range Sea Danger Area (RSDA), unauthorised entry to the RSDA is both illegal and dangerous. QinetiQ manages access to the RSDA ensuring that boats, yachts and personal watercraft (PWC) do not enter the area illegally, putting themselves and their vessels at risk. In order to monitor the RSDA whilst the Range is active, QinetiQ uses marine surveillance radar and has a Range Safety Boat which patrols and advises any unauthorised vessels to leave in accordance with the byelaws and in the interests of health and safety. In recent years, there’s been an increase in vessels sailing close to the Range coastline overnight or on weekends, then becoming stranded within the RSDA, effectively leaving the vessel in an active weapons danger area when the Range resumes explosive operations. This is not only dangerous for anyone on board, but also puts the vessel at risk and can delay important Range operations. Recovery of stranded vessels can be costly and difficult with owners having to wait for the Range to authorise access, and for the right tidal conditions etc. This is one of the reasons that the Inner Sea Area is closed to all marine vessels, at all times irrespective of the status of the Range. Skippers can find guidance on the location of the Inner and Outer Sea Areas that comprise the RSDA on the MOD Shoeburyness website where there is a section dedicated to safety information for mariners. There is also information about how to contact Range Control for advice, and the meaning of the Red Flags that are used to indicate the status of the RSDA. If you or your members sail in the vicinity of the Range, we strongly recommend that you familiarise yourself with the restrictions. Our website also has a guide for anyone wishing to access the inner waterways via Havengore Bridge and we post status alerts on X (formerly Twitter), to notify when either Havengore Bridge or Potton Bridge is non- In addition to the restrictions and prohibitions imposed by the MOD byelaws, the MOD foreshore is included in the ‘Restricted Area’ of a PWC PSPO introduced by Southend- |

Prohibition to Navigation Temporary installation of frame assembly at Colne Barrier Storm Surge Barrier Colne Estuary, Essex Bam Nuttall who are working on behalf of the Environment Agency are scheduled to lift our mitre floodgate of our storm surge barrier this year and to do so, we need to assemble our frame structure at the Colne Barrier. Installation of the frame will be completed on the Southern side of the barrier on the 11th of March and shall remain in place until Summer 2024. The frame would only slightly protrude into the watercourse past the floodgate meaning this would be the item that needs to be considered and the risk of this can be managed by adding sufficient lighting and beacons to the frame to aid river users in avoiding the structure while navigating through the flood barrier.

Essex Police Headquarters, PO Box 2, Springfield, Chelmsford, Essex. CM2 6DN Tel.101 23rd November 2021 Organised Crime Groups – Drugs Importation via Boats & Planes. The purpose of this letter is to raise awareness of an issue relating to Organised Crime Groups and the importation of controlled substances. Essex Police are aware that criminals around the Tendring coastline are using boats and small planes to drop off drugs on the mud banks. These packages are then collected by the criminal gangs and brought ashore and thus avoiding the chances of being stopped by Customs at a port and losing their shipments. These controlled drugs are then distributed and sold within the community of Essex and beyond. As part of our commitment to tackling organised crime, we are writing to the local Marinas and boating community to ask for your support in identifying potential suspicious behaviour so that we can work together to protect our Community. You will undoubtedly be aware of the detrimental effects, misery and harm that drugs bring, not only to our wider communities but, in particular, to those vulnerable individuals within society. How can you help There are a number of signs to look for which may be indicators that these criminal activities are taking place. Signs to look for ➢ Light aircraft making several slow passes over the same strip of coastline ➢ Packages being seen thrown or dropped out of these planes ➢ Mid- ➢ Suspects are seen with binoculars looking out in the same areas where the planes or boats have been visiting ➢ Small boats are launched near to these locations from the back of a trailer or small boats leave local marinas about the same time as the small planes and boats are seen as above. ➢ Suspicious night- ➢ General suspicious behaviour Police will always look to work with the boating community, and we are grateful for your support. Should you have any suspicions or concerns please report them to Essex Police via “101”. You can also report anonymously to CrimeStoppers at crimestoppers- Regards Steve Davey Prevent & Protect OCG Officer Essex Police steven.davey@essex.police.uk |

REQUESTS FOR VESSELS TO PROCEED WITH CAUTION OR AT SLOW SPEED This replaces Portwide Notice 1 of 2021, which is hereby cancelled When a reduction on vessel traffic speed is required, the term “Proceed with Caution” or “Proceed at Slow Speed” is used by London VTS in appropriate broadcasts. The following should be noted by Masters, Berth Operators and other river users when requiring speed reductions requests be broadcast: 1. As a guide, requests for reduction in speed are appropriate for activities such as diving, salvage, heavy lifting, working on the waterline from scaffolding or pontoon/small boat, and bunkering operations. They may also be appropriate where the mooring facilities are limited e.g. when the vessel overhangs the berth or when a vessel is about to take the ground at a Not always Afloat but Safely Aground (NAABSA) berth. 2. A request for a reduction in speed of passing traffic should not be sought as an alternative to good seamanship such as the proper tending of lines and moorings in a tideway. When London VTS has agreed to broadcast a reduction in speed: 1. The activity requiring the speed reduction will be identified in the broadcast, from which Mariners should judge the speed appropriate to the circumstances. 2. The person responsible for the request must ensure that the vessel or installation concerned is displaying the international code flags “Romeo Yankee” by day, and illuminated rigid replica by night. Failure to do so will result in the termination of the broadcast. 3. London VTS should be informed as soon as there is no longer the requirement for a speed reduction and the Romeo Yankee signal removed. The speed reduction broadcast by London VTS will also be terminated. |

RIVER MEDWAY - NOTICE IS HEREBY GIVEN THAT: a recent near miss incident involving a small fishing boat and an LNG Vessel has highlighted an issue surrounding the movement of such ships and the proximity of small boats. LNG vessel movements are extremely sensitive for a number of reasons; the size of the vessel, the level of tug assistance required, the complexity of the berthing/unberthing manoeuvre and the very nature of the cargo they carry. When an LNG ship is transiting the River Medway or in the process of manoeuvring on/off the berth at Isle of Grain all vessels are required to keep well clear and maintain a safe distance. The chart above shows the potential turning circle of an LNG ship and indicates the amount of sea room that needs to be kept clear for the turning manoeuvre. The area highlighted may alter depending on the size of the vessel and if the adjacent LNG berth is occupied by another ship, however, the zone marked is based on the largest LNG vessels expected (345m). When the ship is fast alongside the established LNG berth exclusion zone and associated rules apply to all craft as per Medway NtoM 02 of 2020. UKHO Chart 1834 refers Further information may be obtained from Medway VTS on VHF Channel 74, call sign “Medway VTS’ or telephone 0151 949 6148 or 0151 949 6650. |

IRIVER MEDWAY -
NOTICE IS HEREBY GIVEN THAT : Peel Ports London Medway is committed to providing a safe environment for all river users and reported incidents that demonstrate dangerous behaviour and serious breach of port byelaws will be investigated leading to potential prosecution. We would like to bring to your attention the following statement issued as a result of an inquiry subsequent to an accident earlier this year. “On the 26th of April 2020 a water craft collided with another vessel causing it to sink and causing serious injury to one of the occupants. Police attended the scene and the defendant was breathalysed and found to have a levels of alcohol in his system exceeding the amount permissible for driving a vehicle on the road, resulting in his arrest. The injured party maintained that the defendant had been performing ‘doughnut’ turns around her vessel but had lost control of his vessel causing it to collide with hers. The Port of Sheerness Ltd brought prosecution proceedings against the defendant pursuant to the Port Byelaws alleging that the defendant had failed to navigate his vessel with the requisite level of care and that he had been in charge of his vessel whilst unfit by reason of drink, contrary to byelaw’s 22 and 33 respectively. The defendant was summoned to appear before Magistrates sitting at Medway on the 10th of December 2020. At this hearing the defendant pleaded guilty to both allegations and was ordered to pay fines, compensation and costs totalling £3,950.” |

Lowestoft Harbour and Approaches –Management of Vessel Speed and Wash Lowestoft port has in recent months experienced incidents involving excessive speeds,and/or close passing distances, within the Harbour and its approaches. These have resulted in vessel wash and/or hydrodynamic forces effecting other port users and operations. Mariners and Port Users are reminded that the maximum speed limit within the harbour is 4 knots. However, this should not be regarded as a target speed. Also, at sea the wash from a vessel can be detrimental to other users when it strikes their craft or the shoreline. Passage planning in confined waters should consider safe speed and be compliant with regulatory speed limits. During a passage the speed of the vessel should be closely monitored and adjusted as required. The effects of vessel wash, and/or the magnitude of hydrodynamic forces between vessels, will depend on a complex array of factors, including, but not limited to the following: • The speed of the passing vessel(s). • The passing distance, (with reduced distance leading to greater hydrodynamic forces). • The underkeel clearance and variations in depth, (the smaller the underkeel clearance the greater the hydrodynamic force). • The design of the vessel hull. • The relative displacement of both vessels. • The orientation of the berth to the passing vessel. Due care should be taken when passing vessels, whether in the approaches or in Harbour limits. Speed should be such to minimise the propagation of wash,whilst maintaining full control over the manoeuvrability of the vessel. Necessary reductions in speed should be made gradually and in good time as circumstances allow.

Ministry of Defence (MOD) Shoeburyness: Range Sea Danger Area In anticipation of the lifting of the Government’s COVID- To enable the Range to work safely and ensure that hazardous activities do not present a risk to members of the public, it operates under the jurisdiction of the Artillery Ranges Byelaws 1936 and the Shoeburyness and District Military Lands Byelaws 1935 (under the Military Lands Acts 1892 to 1903). The byelaws govern the use of the land and rights of access and passage through the byelaw area. The byelaws cover an area of the Thames Estuary and the North Sea and the inner waterway that runs from Havengore Creek across to the River Roach and the River Crouch. This area comprises the Range Sea Danger Area (RSDA), unauthorised entry to this area is both prohibited and dangerous. QinetiQ is responsible for managing access to the RSDA and ensuring that boats, yachts and personal watercraft do not stray into the area, putting themselves and their vessels at risk. In order to help monitor the RSDA whilst the Range is active, QinetiQ uses marine surveillance radar and has a Range Safety Boat which patrols the in area and advises any unauthorised vessels to leave in accordance with the byelaws and in the interests of health and safety. To raise awareness of the location of the RSDA and help avoid incursions by unauthorised vessels, there is a section on the MOD Shoeburyness website which is dedicated to safety information for mariners. Here, mariners can find guidance on how to safely navigate in the vicinity of the Range, how to contact Range Control for advice and the meaning of the Red Flags that the Range uses to indicate the status of the Inner and Outer Sea Areas. If you or your members sail in the vicinity of the Range, we strongly recommend that you familiarise yourself with the restrictions. Our website also has a guide for anyone wishing to access the inner waterways via Havengore Bridge (currently closed to marine traffic), and we post status alerts on Twitter to notify when either Havengore Bridge or Potton Bridge is non- We would be most grateful if you could circulate this information amongst your members and other contacts in the sailing and watersports community and where possible, create a link from your website to our Information for Mariners page (see link below). If you have any questions or suggestions for improving the information, please let me know. You may also find the information in the attached leaflet of interest which you can print and circulate amongst your members if you wish. https://www.qinetiq.com/shoeburyness/Public- Nicki Uden – Community Liaison Officer, SHOEBURYNESS RANGE |

INFORMATION Mariners are courteously reminded of Rule 9 [Narrow Channels] of the International Regulations for Preventing Collisions at Sea 1972 [COLREGS] Rule 9 – Narrow Channels (b) A vessel of less than 20m in length or a sailing vessel shall not impede the passage of a vessel which can safely navigate only within a narrow channel or fairway. (d) A vessel shall not cross a narrow channel or fairway if such crossing impedes the passage of a vessel which can safely navigate only within such channel or fairway. The latter may use the sound signal prescribed in Rule 34(d) [At least five short and rapid blasts on the ship’s whistle] if in doubt as to the intention of the crossing vessel. (g) Any vessel shall if circumstances of the case admit avoid anchoring in a narrow channel. All commercial ships navigating in the Burnham Fairway will have a Crouch Harbour Authority [CHA] licensed pilot onboard. They will be monitoring VHF Channel 11 whilst within the CHA district. Do not impede these vessels as they can only navigate safely within the Fairway due to amongst other factors constraint of draught. A ship that is slowing down may not steer very well; it needs propeller action on the rudder to respond, it takes time and considerable distance to stop a ship particularly if it is in a loaded condition. Ships in narrow channels cannot easily avoid small craft, it is best that you stay clear. Be especially cautious and vigilant at night or in times of poor visibility, above all keep a good lookout both ahead and astern. If you cannot see the ships wheelhouse, the ship cannot see you. |

Dangerous Wreck on the Buxey Sand edge of the Swallowtail channel This is an 'unofficial' notice to Mariners. I have been told by Mr Alan Bird, a local oyster dredger and yachtsman who has seen detail of the 'Obstruction' in the channel between the Swallowtail and the Buxey Sand. Charts currently show there is an 'Obstn' drying 2m at 51.40'951N, 001.03'541E. However, Mr Bird records the position as 51°40’924N 001°03’660E - Mr Bird has submitted an H102 to the UKHO but kindly given me details of the wreck and a copy of the images. I have selected the best two images of the overview. Note that the tail end of the Swallowtail can be seen on the left of the image showing how narrow the channel is. The waypoint symbol on the chart image shows the position recorded by Mr Bird. |
