🔍 Key Concepts

• GMDSS sea areas (A1, A2, A3, A4) and how each is defined • The difference between VHF coast station coverage and MF/HF or satellite coverage • What continuous DSC alerting on VHF implies about range and equipment

💭 Think About

• Which GMDSS sea area is specifically linked to VHF radiotelephone/DSC coverage from at least one coast station, and usually has the shortest range? • Look at each option: which ones are satellite ocean regions, which one is defined by MF coverage, and which one is defined by VHF coverage? • Ask yourself: in which sea area are ships required (at minimum) to carry VHF-DSC equipment because they are expected to be within VHF range of a coast station?

✅ Before You Answer

• Verify the formal GMDSS definitions of Sea Areas A1, A2, A3, and A4 in IMO GMDSS regulations or SOLAS Chapter IV. • Confirm that Ocean Area Regions (AOR-E, AOR-W, POR, IOR) are related to Inmarsat satellite coverage rather than VHF coast stations. • Check which sea area’s definition explicitly mentions VHF coast station coverage and continuous DSC alerting.
