1.7 Communications with coast stations

  1.7.1 On VHF channels allocated to port operations service, the only messages permitted are restricted to those relating to the operational handling, the movement and the safety of ships and, in emergency, to the safety of persons; as the use of these channels for ship-to-ship communications may cause serious interference to communications related to the movement an safety of shipping in port areas.

  1.7.2 Instructions given on communication matters by shore stations should be obeyed.

  1.7.3 Communications should be carried out on the channel indicated by the coast station. When a change of channel is requested, this should be acknowledged by the ship.

  1.7.4 On receiving instructions from a coast station to stop transmitting, no further communication should be made until otherwise notified (the coast station may be receiving distress or safety messages and any other transmissions could cause interference).
