Admiralty Hydrographic Notes allow you to inform the Admiralty of any navigationally significant information. This information could include new or suspected dangers, changes to navigational aids, amendments to details included in publications and suspicious charts or publications that could be counterfeit. This information can be submitted in format prescribed by the Admiralty office.
