Small passenger vessels that sail 20 to 100 nautical miles from the nearest land must have what additional equipment?

• A. A satellite phone
• B. MG-HF SSB Transceiver
• C. An EPIRB
• D. An automatic identification system

Answer: (B)

When a vessel operates 20 to 100 nautical miles from the nearest land, long-range radio capability becomes essential for safety and coordination. VHF signals are limited to line-of-sight and typically don’t reach shore or distant ships well beyond near-coastal areas. An HF/SSB transceiver provides reliable communications over long distances by using the MF/HF bands, which is why this equipment is specified for that operating range. The single-sideband (SSB) mode makes long-range transmissions clearer and more efficient, which is important for distress calls, routine checks with coast stations, and coordination with other ships when you’re far from land. The other options aren’t the mandated equipment for this scenario. A satellite phone isn’t required by this rule, though it can be useful. An EPIRB is a critical safety device, but it serves a different purpose and isn’t the specific long-range communications equipment called for here. AIS helps with identifying nearby vessels, but it isn’t the long-range communication capability emphasized for 20–100 nautical miles offshore.
