Monitor Channel 16 as the GMDSS radio watchkeeper: triage every incoming transmission by urgency class, direct each to the correct watch station or relay it if the primary station does not respond, and never let a genuine distress call slip through. Covers the GMDSS compulsory radio watch under SOLAS Chapter IV Regulation 12, the priority hierarchy of VHF traffic, DSC controller operation, and the USCG GMDSS operator examination topics.
Channel 16 is the international distress, safety, and calling frequency. Every SOLAS vessel must maintain a continuous watch. Missing a Mayday is a criminal offence in most flag states. This game trains the sustained vigilance required on a long deep-sea watch.
