River Crouch - 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 River Crouch - Owners and operators of power- 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- 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- |

As a vital tool for maritime safety and operational efficiency, the VHF radio must be used in strict compliance with international and national regulations, including the International Telecommunication Union (ITU) Radio Regulations, the International Maritime Organization (IMO) SOLAS Convention (Chapter IV), and the Merchant Shipping (Radio Installations) Regulations 1998, as applicable under UK law. All river users who regularly operate VHF radio equipment are reminded that VHF radio transmissions must be concise, clear, and strictly relevant to the safety of navigation, operational coordination, or emergency situations. The use of inappropriate language, unnecessary transmission, or non- In accordance with the Maritime and Coastguard Agency (MCA) guidance and the ITU Radio Regulations, priority must always be given to distress, urgency, and safety communications. Channel 16 must be continuously monitored unless actively engaged in a transmission on another channel, and it must only be used for hailing, distress, or emergency communications. Routine operational discussions should be conducted on the designated working channels. Regardless of which channel is used, or the subject being discussed, it is repeated that VHF radio transmissions must be concise, clear, and strictly relevant to the safety of navigation, operational coordination, or emergency situations All communication should be conducted with due respect and without unnecessary chatter or informal exchanges that could compromise the efficiency of maritime operations. Misuse or negligence in VHF communication not only disrupts operational effectiveness but may also endanger lives and maritime safety. |

Thames Estuary - This Notice supersedes and replaces L52- Mariners are advised that the Neuconnect cable lay works have been completed. The attention of mariners is particularly drawn to UKHO Preliminary Notice 4461 (P) / 23 (week 48, publication date 30/11/2023), which indicates the track of the Neuconnect cable; and to any subsequent corrections (whether permanent or temporary / preliminary) in relation to the Neuconnect cable; or new chart editions which may be issued by UKHO. As with any submarine cable, mariners are cautioned against anchoring, trawling or otherwise interacting with the seabed in the vicinity of the cable track. The cable is not considered to pose a hazard to conventional surface navigation. Guard vessels, engaged by the cable contractor, may be on station along the cable track from time to time. Their role is to monitor for vessels posing a risk to the cable by seabed interface and to pass appropriate warnings. They will not intervene in case of routine surface navigation in the area. Various works, including surveys and landfall reinstatement works, are in progress and/or may be undertaken along the track of the cable, including where it passes over the drying areas and is landed ashore. In particular, works in the drying zone may be resumed on a larger scale in April 2025. Various vessels, plant and personnel may be engaged in these works; any vessels are expected to display appropriate lights and shapes in accordance with the International Regulations for Preventing Collisions at Sea (IRPCS) and local regulations. Masters of vessels intending to navigate in the vicinity of the cable track are advised to exercise caution. Information will be broadcast as necessary by London VTS. Further PLA Notices to Mariners may be issued for any of these works as may be deemed necessary. Mariners are also advised to monitor Notices to Mariners which may be issued by Medway Ports Authority relating to Neuconnect- This Notice will remain published until this information is considered adequately promulgated; at that time, |

PLA - In recent years, Spring and Summer has seen an increase in pleasure vessels and narrowboats suffering mechanical breakdown. These incidents vary in type and severity, but are often easily preventable with proper pre- We remind all recreational river users to step up their vigilance and avoid the consequences of neglect to reduce breakdowns. Please check your engines, fuel, electrics, radios, anchors and other essential parts to ensure that they are in good working order and ready in an emergency. Suggested specific questions to have in mind for users Are the air, fuel and oil filters clean and free from biological infection? Are the cooling systems (tanks, hoses and in particular impellors) in good condition, not perished, secure and free from blockages? Are the fuel tanks and hoses clean, free from water and other contaminants and secure? (Significant condensation can occur through the Winter months). Does my vessel have enough fuel for the journey? Are the oil levels correct and has the oil been recently changed? Are the drive and auxiliary belts in good condition and properly tensioned? Are your batteries charged and with good wiring? Is your rudder and it’s fixings in good condition? Is your VHF working correctly? (Perform a radio check with London VTS). Is the anchor suitable for the vessel’s tonnage, the nature of the riverbed, with sufficient chain and warp and the bitter end made fast? (It’s suggested that a minimum of chain and rope should be 5m and 25m respectively for the Tideway. PLA charts should also be assessed for safe anchorages). Mariners are reminded the Tidal Thames is a Category C waterway above Denton Wharf, where wave heights of up to 1.2m and tidal flows of up to 4 knots can be encountered and sometimes exceeded. Vessels should be fully prepared to meet these conditions, which often require engines to work much harder than normal. If engines are underpowered or not maintained for the Tideway, Masters should consider whether the vessel is suitable for navigation. Please note that the calm waters of the UK’s canal system may allow defects such as contaminated fuel or perished cooling systems to go unnoticed. However, once a vessel enters waters that agitate contaminants like dirt in the tanks and demands more from engines; these deficiencies can cause significant failures, blockages and ultimately dangerous situations. If you suffer a mechanical breakdown, ensure your anchor is ready for emergency deployment. If you get into difficulty, with due regard of your location please call London VTS via VHF (Tel: 020 326 07711) to advise them of the situation. In an emergency you can call London Coastguard on Channel 16 (Tel: 999 and ask for coastguard). Recreational mariners are very welcome on the tidal Thames, but it is also a busy commercial waterway, and it is important for everyone’s safety that vessels can complete their journey without putting the crew and passengers on your vessel or others at risk. |

Crouch Harbour Authority - 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. Polite Notice INFORMATION Mariners are reminded that it is not permitted to moor their vessels to navigation buoys or marks. Jetties at Burnham- INFORMATION Please be advised that the jetty moorings in Burnham- See CHA Website for contact details: https://crouchharbour.uk/contacts/other/ The mooring of any vessels alongside Kings Wharf is strictly prohibited. |

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. |

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.

RIVER CROUCH - COURTEOUS NAVIGATION Mariners are reminded of their duty to not only abide by the 8- • Moored craft. • Vessels with tenders alongside. • Small vulnerable craft. 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- |

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. Mariners are advised that it is an offence to proceed at excessive speed where damage or risk of damage may be caused by wash or displacement. Caution should be exercised when passing piers, berth/moorings, beaches, recreational activities and any other areas involving property or persons. All vessels and craft should be operated in a courteous manner with consideration being given to other mariners.

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.

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. |
