🔍 Key Concepts

• GMDSS carriage requirements based on gross tonnage and vessel type (cargo vs passenger) • Minimum number of EPIRBs, SARTs, and survival craft radios actually required by regulation • Minimum number of licensed GMDSS radio operators required on compulsory vessels

💭 Think About

• Compare each choice to what you remember from the basic GMDSS carriage tables: which option overstates or adds extra requirements that are not in the rules? • Ask yourself: do the rules usually jump from one unit to two of each unit at 500 GT, or do they focus on coverage (sea area) and number of persons on board? • Think about whether GMDSS operator requirements are normally expressed as an exact number for a specific tonnage, or as a minimum that depends on watchkeeping and operating the equipment.

✅ Before You Answer

• For each choice, mentally check it against the idea that GMDSS is primarily based on sea area and vessel type, not just tonnage steps at 500 GT. • Verify whether there is actually a rule that says “must carry two of each unit” when crossing the 500 GT threshold. • Verify whether you’ve seen a specific rule that says “at least three licensed GMDSS radio operators” for vessels over 500 GT, or if that sounds like an exaggerated requirement.
