Using Alternative NtM Services
Last updated
This fact sheet provides information for using alternative Notices to Mariners (NtM) services to correct paper charts and nautical publications covering Australia, Papua New Guinea and Solomon Islands. Please note:
- While the Australian Hydrographic Office (AHO) refers to a Paper Nautical Chart (PNC), the UK Hydrographic Office (UKHO) refers to them as a Standard Nautical Chart (SNC) and markets them under the ‘Admiralty’ or ‘British Admiralty (BA)’ brand names.
- A number of services can supply NtM tailored to a vessel’s specific portfolio of charts from multiple nations. These services include Notices for all charts produced by the AHO, which exceeds the number reproduced by the UKHO. Services that include Australian NtM are available from:
- UKHO, Admiralty Notices (for adopted charts only)
- Navtor
- OneOcean Limited
