Overview weekly editions

To support safe navigation, the Hydrographic Service publishes the most important changes to nautical products. It does so by issuing Notices to Mariners (NtMs). Besides browsing the NtMs Database, you can download all notices in a booklet (PDF). This booklet contains all notices of that particular week and is therefore also known as the weekly edition.

If you discover any uncharted dangers, changes, or errors in our products, please let us know by sending an e-mail to: info@hydro.nl.

As of week 17 (29 April 2021), The Netherlands Hydrographic Service will no longer issue tracings for each nautical chart notice. If one or more tracings are available, this will be announced in the NtM concerned ("Tracing available"). The tracing(s) will be uploaded on the website.
