UKHO and Trinity House Permanent/Temporary/Preliminary Notices:
1. ENGLAND - East Coast - Depths. Tidal streams. -
A survey around the Winterton Shoal (off Winterton Ness) has prompted 8 reductions of depth and two new areas of overfalls. All of the depths have ample water for leisure craft but the overfalls will be relevant to us, one of which is west of the Cockle east cardinal buoy for the inshore route, the other to the east of the Cockle leading into the Barley Picle.
2. ENGLAND - East Coast - Depths. - One reduction of depth in the River Thames, Northfield Hope, southeast of the White Hart SHB. Unlikely to hinder leisure craft.
3. ENGLAND - East Coast - Harbour limit. Legend.- Harbour limits for Sizewell C have been defined. The limits extend due east from the bank for two nautical miles! Image of course.
4. EAST COAST OF ENGLAND - APPROACHES TO THAMES ESTUARY - In Week 18, Trinity House provided us notice of intended move of the Longsand Head lighted buoy and the new station of the East Longsand lighted east cardinal buoy. Today they have announced that the changes have now be actioned. The image on Week 18 remains correct. Navionics has made the change already, C-Map has not yet.
