On what channel should you conduct the initial call?

The initial call for maritime communication should always be conducted on Channel 16. This channel is designated as the international distress, safety, and calling frequency, and is monitored by all vessels and coast stations. Channel 16 serves as the primary means for initiating communication, especially for urgent situations, distress calls, and safety announcements.

When a vessel needs to establish communication with another vessel or a shore station, starting on Channel 16 allows for a standard approach that ensures the call is received by others in the vicinity. After the initial contact is made, the parties involved can then switch to a working channel for further communication.

The other channels mentioned do not serve this primary purpose. Channels like 06, 12, and 80 may have specific uses, such as inter-ship communications or local area operations, but they are not used for initial calls, especially in emergencies or for safety-related communications. By adhering to the practice of using Channel 16 for initial calls, mariners ensure they are compliant with international regulations and that their communications are effective and widely received.
