@thebridgeprep: WHAT IS MARITIME SAFETY INFORMATION MSI AND WHY IS IT IMPORTANT? GMDSS interview question Sir. Examiners love this one. Answer: MSI = Maritime Safety Information. It includes: 1. Navigational warnings 2. Meteorological warnings 3. SAR information 4. Other urgent safety-related messages Why important: SOLAS Chapter IV makes it mandatory. Every ship must receive MSI while at sea. If you miss it, you sail blind into danger. How you get it: NAVTEX, EGC SafetyNET, HF NBDP. No MSI received = Detention risk at PSC. Save this for orals and GMDSS interview. This is bridge watchkeeping law. Question: Name 2 ways your ship receives MSI. Comment below. Learn. Practice. Stay safe. #MaritimeOrals #GMDSS #DeckOfficer #SOLAS #MerchantNavy
