2. ENGLAND - East Coast - Depths. - Three new reduced depths for SNC 2692 at the Long Sand Head. A new edition of SNC 2692 was only issued on 28th March! The reduced depths indicate that the Long Sand Head continues the common trend to extend to the NE. I understand it is likely the Long Sand Head North Cardinal which is critical marking the tight corner in the two-way TSS will be moved in due course. The image includes 3 other reduced depths in that area that were reported earlier in NtM 1378 in Week 13.
3. ENGLAND - East Coast - Depths. - An unusual event here; a NtM reporting an increase of depth. One very slight increase of depth in the River Thames in the south end of the Lower Hope Reach just south of the Ovens SHB. Unlikely to hinder leisure craft.

The scientific instrument will stand approximately 2m in height above the sea bed and will be marked with two special mark buoys, flashing a yellow light every 2.5 seconds, positioned NE / SW either side of the instrument. Mariners are advised to navigate with additional caution in this area and pass well clear of the temporary buoys.
3. Harwich Haven - Dredging Operations – Update 3 - dredging operations are taking place as follows:
➢ C-Force (IMO: 9850305) – currently carrying out plough dredging operations in the main channel near the Cross buoy, around the Beach End area, in Harwich Harbour, the River Stour and Mistley. Expected to continue until approx. 8 April 2024.
➢ Shoalway (IMO: 9556337) - will commence trailing suction hopper dredging around 4 April 2024 for approx. 3 - 6 days. Weather permitting, the dredging operations will predominantly take place in the Harwich Deep Water Channel, however some dredging may also take place in Harwich Harbour and around the Port of Felixstowe as required.
➢ Sospan Dau (IMO: 7711062) – will commence trailing suction hopper dredging on approx. 15 April 2024 for around 3 - 4 days. Maintenance dredging will be taking place in the Harwich Haven and around the Port of Felixstowe, with material disposed to the beneficial sites in the River Stour and Orwell (see diagram in the Local List). This dredging notice is cumulative and replaces notice No. 17 of 2024 (update 2), which is now withdrawn.

Turbine M20 - 51° 41.902'N 001° 30.042'E - FL. Y 5s 5NM - Light Extinguished. Fog Signal Inoperative/Incorrect
Turbine G20 - 51° 39.458'N 001° 26.619'E - FL. Y 5s 5NM - Light Extinguished.
Further updates to be provided as rectification takes place.
I have attached an image in the Local list showing the localion of the affected turbines. Messrs H04 and J06 ar on the flank of the Kentish Knock whilst Messrs M20 and G20 are along the Back Deep (I assumed turbines have identified their gender as male. )
That is it.
