Details

A global maritime distress and safety system (GMDSS) is a maritime communications system for all vessels. A total GMDSS system is made up of:

  • digital selective calling (DSC) via radio
  • satellite communications
  • Navtex - weather and transport information
  • search and rescue radar transponders (SARTs)
  • emergency position indicating radio beacons (EPIRBs)

A pleasure craft may not need a complete GMDSS package but MCA recommends that owners and operators make sure they at least fit a VHF DSC radio.

  • distress alerting
  • safety broadcasts
  • routine calls
  • group calls
