🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) was created mainly for SOLAS vessels on international voyages • Think about gross tonnage thresholds and passenger vs. cargo when equipment requirements start to apply • Consider whether GMDSS applies to all vessels or only certain classes engaged on specific voyages (e.g., international/SOLAS)

💭 Think About

• Which types of vessels are covered under SOLAS for radio communications, and what minimum gross tonnage is commonly used as a cutoff? • Does GMDSS apply to every small coastal boat, or is it aimed at larger commercial/passenger ships on certain voyages? • Look at each option and ask: is this too broad, too narrow, or a good match for the intent of SOLAS GMDSS requirements?

✅ Before You Answer

• Verify the 300 gross tonnage threshold in SOLAS/GMDSS requirements • Confirm whether passenger vessels are treated differently from cargo ships under GMDSS rules • Check if GMDSS is tied to international voyages/SOLAS vessels, or simply to operating outside VHF range or being “capable” of such voyages
