Week 31

UKHO Permanent/Preliminary/Temporary

1. New Editions of ADMIRALTY Charts published 2 August 2018 - Chart 1835 England - East Coast, River Medway, Folly Point to Maidstone, A Continuation of the River Medway, B Continuation of the River Medway to Maidstone. Includes changes to depths from the latest Medway Port Authority Surveys;
2. ENGLAND - East Coast - Wrecks. - Three revised depths over already known wrecks to the east of the Sheringham Wind Farm. All at a depth that they are unlikely to hinder leisure craft;
3. ENGLAND - East Coast - Works. Buoy. Depths. - A restricted area off the Bawdsey beach for drilling for the East Anglia One Wind Farm. The instructions opposite are explicit. No mooring, no fishing. The area limits the inshore route from the Deben to the Ore. Not strictly an exclusion zone but going outside the Waverider buoy would make sense! Depths may be more shoal than charted in the vicinity due to the drilling works; - See the image for the area at: http://www.crossingthethamesestuary.com/page9.html
