Channel 16. Marine channel 16 is the international calling and distress channel. Whilst marine radio has limited range, the coastguard of every country monitors channel 16 in their coastal waters 24 hours a day - 365 days a year. Additionally, anyone using a boat fitted with a VHF radio is expected to monitor channel 26 if they're not using the radio themselves.

Channel 16 is internationally recognized for "Hailing and distress". The norm for professional mariners is to monitor 16 all the times. Ch 16 can be used also to hail a variety of vessels and land stations (related to maritime activities).An example of how a proper hailing might go."M/V Mary J this is F/V Sudden Relief on channel one six over" Reply "Sudden Relief this Mary J please switch and answer to working channel six eight, over".Channel 16 should NEVER be used for regular conversation. Maydays, local notice to mariners, and information may be announced over 16 and anything but a "Mayday" will be directed to a pre-selected alternate channel to pass the actual information.
communication using computers is digital communication while that of physical or written channel is analog communication.
