Ship's callsign shall be used on initial contact with Marshal Control.

Initiating contact with marshal control by using the ship’s callsign establishes who is speaking right away. In busy radio environments, the first part of every transmission should identify the transmitter so the controller can match the message to the correct vessel and route instructions accurately. The callsign serves as the primary identifier, helping prevent confusion when multiple ships or vehicles are on the same frequency. Once identity is established, you can add position, intent, or other details, but the critical first step is to state the callsign.
