What is the best frequency for emergency communication on the water?

VHF Channel 16 is recognized internationally as the primary emergency communication frequency for vessels. This channel is monitored constantly by maritime authorities, and it serves as a calling and distress frequency. When a vessel is in distress, the crew can transmit an urgent message that can be quickly received by nearby vessels and rescue services.

The reason VHF Channel 16 is preferred over the HF band, UHF band, or LW band lies in its effectiveness for short-range communication, which is vital in maritime emergencies. It typically provides clear and reliable voice communication within a range that is appropriate for distress situations, where rapid assistance is critical.

Other bands such as HF, UHF, and LW serve different purposes in marine communication and may not be as regularly monitored for emergencies as VHF Channel 16. Therefore, for immediate distress signaling and the best chance of being heard and assisted, VHF Channel 16 is the optimal choice.
