Personal safety or safety at sea is the top priority. Marine radios are important boat safety equipment used to prevent personal injury or loss of life and avoid damage to the environment and ships. Proper use of radios enables rescuers to quickly and efficiently assess the situation and act accordingly.
Marine Distress Signals
“MAYDAY, MAYDAY, MAYDAY”- This signal is only to be used when a person, or boat is threatened by grave or imminent danger, and requires assistance. If you issue a MAYDAY call, put everyone in life jackets first.
“PAN PAN, PAN PAN, PAN PAN”– This signal is used for urgent messages that aren’t emergency, like when someone has fallen overboard, or a boat is drifting into shore or a busy shipping channel.
SOS in Morse Code- Using marine radio or another signalling method to send it, like continuously using sound signalling equipment for SOS.
Emergency Channel On Marine Radio
CHANNEL 16: Channel 16 (156.8 MHz) is designated as the national distress, safety and calling frequency. All vessels should monitor this channel while underway. All non-emergency traffic should be communicated on another channel (not channels 9 or 16).
