🔍 Key Concepts

• GMDSS basic capabilities: distress alerting, alert reception, SAR (search and rescue) coordination, and general safety communications • Maritime Safety Information (MSI): what it is (navigational warnings, weather, safety info) and whether GMDSS requires the ability to receive it or send it • Difference between general communications, distress/safety communications, and locating signals (homing to the scene of distress)

💭 Think About

• Ask yourself: What are the core safety-related things every GMDSS ship must be able to do, regardless of sea area? Which option lines up best with those core functions? • Which is more important from a regulatory perspective: being able to send MSI to others, or being able to receive MSI broadcast from shore? • Look for the option that combines distress alerting, safety information, and communications with rescue authorities, not just ship-to-ship or bridge-to-bridge traffic.

✅ Before You Answer

• Verify in GMDSS references that the system must be able to transmit AND receive distress and safety communications, including distress alerts and SAR traffic. • Check which functions explicitly include Maritime Safety Information (MSI) reception, rather than originating MSI for others. • Confirm that locating signals (like those from SARTs or EPIRBs) are part of the required capabilities related to search and rescue, and see which choice uses them in a realistic way.
