GMDSS Radio Courses

GMDSS COURSES

There are four separate marine radio courses in the UK and Europe. Anyone (16 yrs and over) can take any of the four courses, there is no requirement to hold one certificate before taking a higher level courser (however we recommend you hold the 1-day SRC before progressing to the 4-day LRC course.

The table below identifies which GMDSS certificate you are required to hold;

Type of vessel Sea Area A1, (VHF Range of a coast station) Sea Areas A2 – A4, (Beyond VHF range)
Yacht, Workboat or Fishing Vessel under 24m  SRC, ROC, LRC or GOC LRC or GOC
Cargo ship under 300 gt SRC, ROC, LRC or GOC LRC or GOC
Yacht, Workboat or Fishing Vessel over 24m ROC or GOC  GOC
Cargo Ship over 300 gt ROC or GOC GOC
Passenger Ship (any size)
ROC or GOC GOC

SHORT RANGE CERTIFICATE -VHF

VHF (Very High Frequency) is the standard marine radio around the coastline. The RYA Short Range Certificate (SRC) course can be taken online or in the classroom.

The SRC course is followed by the RYA SRC Exam which is usually taken at our centre. If you book the classroom course there is no need to book the exam as it will follow on at the end of the day. If you book the online course then we will need to agree a time for the face to face exam (which can only be take in person, not online). Most students take the exam at our centre in Southampton or Dumbarton but we have access to examiners across the globe.

LONG RANGE CERTIFICATE – VHF, MF /HF (SSB)

Medium Frequency and High Frequency sets, often know as Single Sideband (SSB) give the operator more range and are popular for ocean cruising, blue water sailing and long distance passages.  The LRC refreshes and builds on the content of the SRC.

If the vessel is fitted with SSB then there is a legal requirement for the operator to be trained and qualified in its use. The 4-day course includes the AMERC exam on the final day.

RESTRICTED OPERATOR CERTIFICATE – VHF

The ROC is basically the commercial seafarers equivalent of the SRC. Like the SRC course this longer courses focuses on VHF Radio. The longer course is required by SOLAS vessels over 24m. It can be use on any sized vessel as an alternative to the SRC.

GENERAL OPERATOR CERTIFICATE – VHF, MF /HF & Inmarsat

The GOC is basically the commercial seafarer’s equivalent of the LRC and sits above the other 3 courses. The GOC holder can  operate any marine radio on on any vessel, at sea anywhere in the world. Like the LRC course this longer courses focuses on long range communication, so covers MF and HF (SSB) as well as Inmarsat C and Inmarsat Fleet Broadband. The course is required by vessels over 24m. It can be used by anyone as an alternative to SRC, LRC or ROC. The 8-day course includes a 2.5 hour exam on the last day.
