Here we provide any downloads or links that may be needed to keep your current edition of ECP up to date, and to assist pilotage in our area.

Downloads can be printed using Adobe Reader or direct from your browser, and will either be replacement chartlets or diagrams for pasting into your book over the

originals, or in some cases they are extra features such as the Stone Point chartlet. Any replacements are exactly the same physical size as those in your book, so take care with any re-scaling options that your printer may offer you.     

Don’t forget that home PC printer inks are often not waterproof! ECP reader Peter Jones suggests that you can “…… spray printouts with Winsor & Newton Artists’ Fixative (intended for pastel, charcoal and pencil).  While a drop of water makes the print very slightly fuzzy, it is still legible.”  Or you can of course encapsulate your printouts if you have access to a laminator.

Our current 2020 Deben and Ore entrance chartlets are drawn from the 2019 surveys because new Trinity House survey work has been on hold during the lockdown. However the chartlets do show the current buoy positions, which are based on local knowledge, and include recent aerial photographs.

Please be sure to read the note that is included in each download.
