2. Harwich Harbour – New position for obstruction on seabed- reduction in charted depth – new location for the previously reported object on the seabed. The object is now located 100m on a bearing of 347° from the Grisle Buoy’s charted position, with coordinates 51° 56.942556’ N, 001° 18.258423’ E (WGS 84). The minimum available depth above this object is 13.4m below chart datum (1.1m reduction in charted depth).

4. East Coast of England – The Wash – Approaches to Kings Lynn – Establishment of new Special Mark Buoy – on or about 22nd November 2018, 1 new Special Mark danger buoy will be established to indicate a newly designated Foul Ground* area on the seabed at the following locations: • Yellow Special mark buoy “Z2” – Pillar Y, Cross Y ‘X’ topmark, Fl (4) Y 10s in position Lat 52° 54.050’N., Long 000° 16.115’E. The area of foul Ground extends approx. 1000m to NNE and 1000m to SSW from the above position. *Foul Ground is defined as “as an area of foul ground, not dangerous to surface navigation, but to be avoided by vessels anchoring, trawling etc”. The chart symbol for foul ground is a pecked line surrounding a # symbol. The attached chart extract details the location of the foul ground and associated Isolated Danger buoy. I have added their chartlet to the usual page on the Temporary List;
