Which channel is designated for international hailing and distress communications?

The channel designated for international hailing and distress communications is 16 (156.800). This channel is recognized globally for emergency communication and is monitored by vessels and shore stations for distress calls.

Channel 16 is the primary frequency utilized for calling other vessels and for distress, urgency, and safety communications. Any vessel in distress or needing assistance is encouraged to transmit their situation on this channel to alert nearby vessels or authorities.

Other channels mentioned may have specific functions such as communications with bridge personnel or specific operational uses, but channel 16 remains the standard for international communications related to distress and hailing. This importance emphasizes the necessity for all mariners to monitor channel 16 when navigating to be aware of any distress situations and to be able to respond accordingly.
