Rescue 21 System is associated with which SEA AREA?

• A. SEA AREA A1
• B. SEA AREA A2
• C. SEA AREA A3
• D. SEA AREA A4

Answer: (A)

Rescue 21 is built around VHF-FM radio communications along the coast to manage search-and-rescue coordination. This shore-based VHF network provides continuous distress alerting and coordination within line-of-sight reach of coast stations, without depending on MF/HF or satellite coverage. That places it squarely in Sea Area A1, the region covered by coastal VHF networks. The other Sea Areas correspond to MF/HF or satellite coverage (A2, A3, A4), which Rescue 21 does not primarily rely on.
