Which communication channel is primarily used for distress calls?

Channel 16 is recognized as the international distress frequency for maritime communication. It operates on a VHF frequency of 156.800 MHz and is designated specifically for distress calls, safety messages, and calling other boats. When a vessel is in distress, it is essential to have a reliable and standardized channel for emergency communications. Channel 16 serves this purpose by allowing mariners to communicate their emergencies to nearby vessels and shore stations quickly and effectively.

The significance of Channel 16 is further emphasized by its mandatory monitoring requirement for all commercial vessels. This ensures that someone is always listening for distress signals, which can be critical in saving lives and responding to emergencies at sea. Prioritizing an effective response to distress situations, all vessels must maintain a watch on this channel while underway.

Other channels listed may facilitate communication for specific purposes or local operations, but they are not designated for distress calls. This distinction makes Channel 16 unique and essential for maritime safety.
