🔍 Key Concepts

• NAVAREA warnings vs local/coastal warnings • Purpose of Maritime Safety Information (MSI) broadcasts • Difference between local hazards and wide-area / international navigation hazards

💭 Think About

• Which options affect ships navigating across large sea areas, including international voyages, not just one harbor or local area? • Which events are temporary and local, and which are important enough to be distributed to all vessels in a whole NAVAREA? • Think about what kind of information a vessel mid-ocean would actually need to receive by long-range NAVTEX/SafetyNET.

✅ Before You Answer

• Identify which choices describe a local harbor or coastal issue instead of a wide-area sea navigation issue • Ask: Would this information be relevant to all ocean-going ships in the NAVAREA, or only to vessels close to a specific port or bay? • Check which event could significantly impact route planning and safety over a broad region rather than just near shore.
