Selecting the most appropriate Marine Radio Operator's License for your requirements can be like navigating a minefield!

The Marine Radio Operator's License recommended by eNautical is the MRROC (previously the RRTOC) as this qualification covers the operation of both VHF and Single Side Band marine radio within NZ.

The Maritime Restricted Radiotelephone Operator's Certificate covers mandatory requirements and is the minimum requirement for commercial vessels and users of MF/HF (SSB) radio.

Note that the Maritime Short-range Operator's Certificate (MSROC), an ITU Maritime GMDSS Certificate, is a requirement for anyone wishing to operate a VHF radio in Europe.

The Coastguard VHF Course is not a qualification that Radio Spectrum Management delivers.

The Safety Of Life At Sea (SOLAS) International Convention is the most important treaty protecting the safety of merchant ships. It divides all vessels in two groups: SOLAS and non-SOLAS vessels:


Non-SOLAS vessels do not need to comply with GMDSS radio equipment carriage requirements. Some countries have incorporated GMDSS radio equipment carriage requirements into their domestic marine legislation that is valid for non-SOLAS vessels under their flag. In New Zealand, non-GMDSS Operator's Certificates may continue to be used for the purposes they were issued for.


SOLAS vessels are all cargo ships of 300 GT and upwards and all passenger ships with some exceptions. SOLAS vessels need to comply with GMDSS sattelite and radio equipment carriage requirements.
