Q

Which of the following would indicate a MOB AIS SART?

🔍 Key Concepts

• MMSI number structure and what the first three digits represent • Difference between AIS-SART devices and MOB AIS devices in numbering • How special-purpose AIS devices are assigned unique MMSI prefixes

💭 Think About

• Look at just the first three digits of each option. Which of these looks like a special-purpose search and rescue or MOB device rather than a normal ship or coastal station? • Recall (or look up) which MMSI prefix is reserved specifically for MOB AIS SART / AIS personal locator type devices. • Ask yourself which option matches the standard format: 9xxyyyyyy, where 9xx indicates a SAR-related AIS device.

✅ Before You Answer

• Verify which 9xx MMSI prefix is assigned to AIS-SART versus MOB AIS devices in current ITU/IMO guidance. • Eliminate any MMSI starting with digits that are clearly assigned to ordinary ship stations or coast stations (not SAR devices). • Confirm that the choice you pick has the correct three-digit SAR/MOB prefix and the correct 9-digit MMSI length.
