This notice provides five UKHO blocks for different SN and SC charts.  The images effectively deal with three areas.  First, the coast just east of Calais, second, the approaches to the West port of Dunkerque and finally a detailed block of the Haut-Fond de Gravelines bank off Dunkerque.  

The notice includes several isolated changes:

2. Emendation of the light characteristics of the Harbour Entrance light on the east side of the Dunkerque east entrance.  The change is to add ‘12m’.

3. Adding a Obstn of 7m in the Riden de la Rade east of the Calais entrance.  Some charts already show it.

4. A reduction of depth to 8m from 11.5m east of Calais and a ‘Less water reported 2021) solely for UNHO SNC 1892.  All other charts already have those corrections.

In the area of items 3 and 4, recent NtM 4769 had published 5 reductions of depth. This is now included in the images.  The download of images now total 7 (5 displayed).
