Specialist Courses in Marine Radio Communication


The Global Maritime Distress and Safety System (GMDSS) became operational more than a decade ago - and an increasing amount of GMDSS VHF equipment is now available for small craft. To prepare sailors for VHF communications in the GMDSS era, the RYA has introduced the GMDSS Short Range Radio Certificate (SRC). 

The SRC is a mandatory qualification for operators on small craft fitted with VHF Digital Selective Calling (DSC).


    - Mariners with VHF DSC installations (all new VHF equipment on sale in the UK is required to be DSC compatible). - MCA Code of Practice small craft operating in GMDSS Area A1.
