Announcing several new charts from Belgium is because the UKHO versions will cease on 6th March. Previously Belgium issued chart new editions and the UKHO would then adopt them as ADMIRALTY charts a few months later. Now the UKHO will publish the Belgian Charts in their own series as BE charts, but both the UKHO version and Belgium’s will be the same and updated at the same time. NMs for the four new BE Charts (BE 11, BE101, BE102 and BE 106) will be issued through UKHO NM bulletin as normal and available from the website. Chart 1872 is to be deleted from Notices 3183(T)/23, 3999(T)/24, 286(T)/25, 771(T)/25 and 866(T)/25. Chart 1873 is to be deleted from Notices 3183(T)/23, 286(T)/25, 771(T)/25 and 1123(T)/25. On withdrawal of this chart former Notice 5099(T)/24 is cancelled. Chart 1874 is to be deleted from Notices 3183(T)/23, 3999(T)/24, 771(T)/25 and 1123(T)/25. Charts 1607 and 1975 are important charts for us as these are followed by the echart makers. |

Note the image at the Deben will be out of date, it is merely used to show where the drying height is recorded.

The series has published 36 reductions of depths from Winterton Ness and Kessingland. This Notice is adding four reductions of depth from Hemsby Hole to just north of Great Yarmouth. As such the new reductions should not hinder leisure craft. The notices in in 2025 is 448(P) and 2024 are: 4389(P), 4628(P), 4900(P), 5001(P), 5018(P), 5069(P) and 5165(P).
