1. River Thames, LONG REACH – ESSO No.1 JETTY – FENDER REFURBISHMENT WORKS – On or about 9th November 2020 works will commence to refurbish the fender panels at Esso No.1 Jetty, which are anticipated to take approximately six weeks. The chartlet below depicts the location and marine footprint of the works: The works, which will involve heavy lifting operations, will be undertaken from the crane barge RAVESTEIN between the hours of 0600 and 1800.
Safety boat DIVECO V will also be in attendance during the works. London VTS will broadcast requests for vessels to “proceed with caution” or “proceed at slow speed”, as described in Permanent Notices to Mariners 4 of 2014 as required by the works. International Code Flags “Romeo Yankee” will be displayed when this is in effect. Further details will be broadcast by London VTS on VHF Channel 68 as required.
2. Harwich – Ha’penny Pier Pontoons – We advise visiting sailors using the Ha’penny Pier pontoons that the facility is now unmanned for the winter season. Our Pier Masters will be back on duty during the last week of March 2021. The gate accessing the pontoons from Ha’penny Pier is currently under repair and will remain open for the next few days. However, for security reasons and following incidences of vandalism and unsocial behaviour the gate will remain shut throughout the winter. Harwich Haven Authority gives priority usage of the Ha’penny Pier pontoons to local fishermen during the off season. Sailors should note that if the bridges connecting the pontoons are raised… it is unsafe to enter the mooring facilities.
Ha’penny Pier and the pontoons are under 24 hour CCTV surveillance. The Pier Masters’ telephone will be manned between 0900 -1600 during the winter season – 07748-154039. Alternatively, email Please see our 2020 Yachting Guide, which contains safety of navigation information and all emergency contact details –…/HHA-YACHTING-GUIDE-COMPOSITE-2020_FINAL…
