The South- Download Created 27th May, 2024 NEW - |
On 25th May, 2024 we conducted a survey of the SW Sunk swatchway. Conditions were good with light 5 to 8 kts winds and good visibility. We collected data for just short of 4 hours and the chartlet is created using Surfer software and 13507 soundings. There is a little change with the SW Sunk knoll continuing to advance to the North. The advance over the past winter has been about 100 metres so I have adjusted the west and central waypoints. The central waypoint has been moved north to distance it from the knoll and any tide effect. On a flood tide a tide rip runs in front of the north and north- Depths remain very good and with a comfortable width. |

The Spitway NEW - Re- |
This is a CTTE chartlet based upon resurvey on 25th June 2024. Compared to 2022 there has been a little loss of depth especially on a line between the Safe Water Buoys. Best water remains to the east of the Safe Water Buoys. Note that NtM 3316/2024 has added a second wreck at the Spitway and that is included in the download. |

The Knoll NEW - Surveyed September, 2024 following NtM 4208 in week 37 (wc 02- For Readers: a replacement image for Page 44 can be downloaded below here: For Readers: NtM 4414(P)/24 referenced in the Consolidated Update of 21st September, 2024 can be downloaded here: |
This is a CTTE chartlet following a survey on 7th September, 2024. Ideal conditions with 70787 soundings. The Knoll is on the south side of the entrance to the River Blackwater and is marked by the NW Knoll PHB. The Knoll has always been there but over the years the drying part has moved. There has been no survey in that area since 1985 so UKHO charts (and all that following it) are out of date. If heading to and from between the Spitway and the Blackwater care should be taken to follow the buoyage unless you are confident about the height of tide. On a windy day, especially on a spring tide, there can be some agitation there. |

Times of opening of Havengore Bridge Downloads Created 27th May, 2024 NEW - Click on each Image to Download PDFs Jeff Peters, who sails out of the Orwell, has completed quite a lot of work to produce tables which show the times the Havengore Bridge and he is keen to share his work. Jeff has been sailing the east coast for 10 years on his classic cruiser Blue Shoal out of Orwell Yacht Club in Ipswich. He started sailing at 11 with the first Rainham Sea Scouts before moving to Whitstable and joining the Yacht Club where he learned to race dinghies. He stopped sailing when he went to University due to lack of funds but restarted in 1989 racing a Merlin Rocket and since 1997, Scorpions at Nottinghamshire County Sailing Club. Notes on the spreadsheet showing opening times for Havengore bridge
These sheets are the output from an Excel spreadsheet that Jeff produced partly out of interest, partly to be useful and partly as an intellectual exercise during some of the wetter days this winter whilst recovering from shoulder surgery. The Havengore bridge is generally open for 2 hours either side of high water Southend, during daylight hours (sunrise to sunset) and when the range is not active (the range is active Monday to Thursday 06:00 to 16:30, Fridays 06:00 to 12:30 and at other times that the range operators may choose). The bridge has also been known to break down frequently. The sheets should be treated merely as a quick check to see when the bridge may be open so that you can make your own assessment. Of course, you will also need to determine whether there is sufficient depth of water for your craft in the prevailing sea state and that there is sufficient time for you to leave the restricted area before the range becomes live. Generally, Jeff suggests you follow the guidance in the excellent East Coast Pilot. The sheets are based on a minimum predicted high water at Southend of at least 5m (this anecdotally being when there is 5 feet ( 1.5m ) of water over the Broomway and may be enough for shoal draft boats) so if the tide height is less that 5m the sheets indicate the bridge is closed even though it may be open. The sheets are also based on the latest sunrise and earliest sunset in the month. The sheets do show that there are occasions when the bridge is technically open for a very short period, perhaps just a minute or two, and it would seem unlikely that the bridge will be operational. Jeff suggests if the sheet does not show the bridge being open at high water for at least an hour it would be better to contact Quintiq for confirmation. The tables I have highlighted in red when the bridge is operational but not at high water. The data used for the sheets are: The operational criteria from Quintec who operate the bridge The tide tables produced by Port of London Authority for Southend The sunrise and sunset times for Southend from time and date.com |

Buoy changes at the Long Sand Head NEW May 2024 |
On 20th May, 2024 Trinity House have issued a Notice to Mariners confirming the completion of the changes at the Long Sand Head.. In the past 12 months, the Long Sand Head has continued gently, but persistently, to creep more to the northeast. For us there is no crisis but heed the warning not to ‘cut the corner’. For shipping using the Two- The changes are: The creation of a new east cardinal buoy. This will be positioned very close to current position of the Longsand Head north cardinal buoy. The new buoy will be designated ‘East Longsand Head’. Characteristics are shown in the chartlet. Note it will have AIS. The Longsand Head north cardinal buoy will be moved west and a little north. As you will see in the chartlet the effect is to make the corner clear for shipping. Characteristics for this buoy will remain as at present. |

The Little Sunk Adjacent to the Barrow No 2 PHB NEW 2023 Surveyed on 10th July, 2023 |
This is a CTTE chartlet based upon a survey conducted on 10th July, 2023. The Little Sunk (discussed on Page 24, 3rd Edition) is is usually a stable crossing place and it remains so in 2023. Arguably it has lost 0.2m of depth but it has a controlling depth of 3.2m in the centre. The crossing area is bounded by two wrecks to the south- |

Mersea Quarters Buoyage as August, 2019 (Tollesbury No 4 now placed back) |
This is a CTTE chartlet based upon a survey completed during October, 2016. Changes to depth across the Quarters has required a change to the buoyage which was re- Deep draught yachts (i.e. @2m draught) is recommended to follow the suggested route at LWS. Note this has been amended this month (May) to show the 'Obstn' SW of the Nass Beacon is not now annotated as ED. It DOES exist and should be regarded as dangerous to leisure craft. |

Bradwell Creek New chart 2020 |
Re- The chartlet is drawn to Chart Datum. I have just added a table of Tidal Height predictions at Bradwell Creek which I hope will assist new visitors. When printed the chartlet is best in A3 size. It is difficult to include all the detail in A4. None is omitted so it will be quite small. Of course as a PDF or JPG it can be enlarged as you wish. |

Lawling Creek Revised September, 2014 |
