Module 4 - Channels & Frequencies

Intership And Working Channels

Intership channels such as 6, 8, 72, and 77 are commonly used for ship-to-ship working traffic where appropriate. Local channel plans still matter, and some channels have special uses in particular areas.

The habit is to keep the calling exchange short, agree or accept the working channel, then move the conversation away from Channel 16.

Key points

  • Use working channels for the working conversation.
  • Check almanac, harbour guidance, and local instructions.
  • Use low power first for nearby routine intership calls.
  • Keep a watch on required safety channels after the exchange.
