Notices to Mariners Week 35

UKHO Permanent/Temporary/Preliminary

1. ENGLAND – South East Coast - Drying height. - Ramsgate Harbour: There are two identical NtMs: first NtM 4406(P) which is for the new drying height in relation to Chart 1827 and the second NtM 4441 which is for the same change but in relation to the new block published last week for Chart 1828. The practical consequence is an extension of the drying mud between the West Pier and the RoRo berth. Usually none of us go near there!
2. ENGLAND - South East Coast - Depths. - Three reductions of depth at the SW Goodwin. Earlier this year in the same area, NtM notified of two reductions so they have been included in the image. None likely to hinder leisure craft. (Comparing back to the pre-2013 depths, the SW end of the Goodwin has shallowed significantly – but not an issue for leisure craft).
3. ENGLAND - East Coast - Wreck. - New dangerous wreck in the River Medway in Chatham Reach/Upnor Reach close to the Boat Slip Wharf.
4. ENGLAND - East Coast - Depths. - Three reduced depths in the Sunk Precautionary Area but at over 19m will not hinder leisure craft.
5. ENGLAND - South East Coast - Drying contour. Drying height. Depths. Wreck. - 8 reductions of depth on the Brake and Downs Banks.
6. ENGLAND - East Coast - Obstruction. - This is the new obstruction on the point of St Peter’s Flats on the south side of the Blackwater that was reported last week in the Temporary List.

7. Havengore Bridge Update (19.08.19) "Our contractors will be on site from 2-4 September to repair the current hydraulic fault. Assuming the works go ahead as scheduled and no additional issues are encountered, we expect the bridge to re-open to marine traffic by 5 September. We will issue a further update if there are any changes to this information." I feel tempted to have a ceremonial attempt on 5th September!

That is it.
