2. DOVER STRAIT - Depths. - One reduction of depth in the SW bound TSS in the Dover Straits south of the Varne lightship. Very unlikely to hinder leisure craft.
3. ENGLAND - East Coast - Depths. - New reduction of depth at the north entrance of the Fisherman’s Gat. Whilst still ample water for us (8.3m) the reduction is over a metre so is significant. Earlier this year there are been two NtM close to the same location which are included in the image provided.

5. BELGIUM - Buoy. - In week 20 this year we had a preliminary notice (2082(P)) advising us of a ring of cardinal and special buoys marking the works area for the development of the new Princess Elisabeth Island. This is in Belgium waters east of the Twin special buoy marking the east side of the Noord Hinder TSS. This notice is advising us that the southerly yellow special buoy is deleted. Note that the area within the ring of remaining buoys is a prohibited area.
