What is the channel number for Coast Guard Lesion communication?

The channel number for Coast Guard Liaisons is 22A, which is specifically designated for communication with the Coast Guard for non-emergency purposes. Channel 22A allows for direct communication between vessels and Coast Guard stations for consultations, inquiries, and logistical support without congesting the primary emergency channel, which is channel 16.

Channel 16 is mainly reserved for distress and safety messages, making it critical for emergency communications. Similarly, channel 21A serves a different purpose related to different areas of operations or specific types of communications and does not specify the liaison functionality as clearly as channel 22A does. Therefore, channel 22A is the best choice as it is laid out to facilitate communication effectively with the Coast Guard while avoiding interference with emergency response channels.
