MRCC working & safety VHF channels

Despite all the pilot books/almanacs etc I have and of course internet, I'm struggling to find good info on how UK coastguard stations use VHF.

Could somebody give me an overview on how it all works over there?

For instance, you have continuous listening watch on C16 by all stations for emergency & calling and C67 is for "small boat safety". What exactly does this mean? C67 is for emergency as well but only if you're small? Or is it for filing passage reports etc? Or would passage reports be on another working channel? Does each MRCC have their own different working channels?

I've got a book of marine vhf channels, it lists several working channels for each MRCC but doesn't tell you the specific purpose for each.

Could someone enlighten me please??

Ch16 is used as the listening watch by all & is the channel to raise CG on - Brixham / Weymouth or whichever station you require. For routine traffic they'll direct you to another channel - usually CH67 in my experience to continue the transmission.

From what I've heard I think they prefer you call them directly on another channel unless it's urgent, although which channel I wouldn't know.

Over here the working channels are used for all non-emergency traffic. Announcements of CG info calls will be made on 16 and move to the appropriate local working channel. Other than that, local working channels are general purpose. Hailing the CG for routine traffic is on the working channel.

In addition, our local fisherfolk make good use of the working channels to call in distress issues to the CG, as they know their buddies can't hear them as they're duplex...

(Malin Head CG, this is Sean on the Deep Harvester, we have a wee problem)
Deep Harvester Malin Head what is your problem?
(Malin, we have been taking on water for a few hours and we were OK but then we needed the second pump and that was OK but now the second pump has failed and we thought we'd give you a heads up)
Deep Harvester Malin Head - we are initiating a MAYDAY please advise your exact location
(Ah jaysis Malin, early days for that - could you not just get the lads on the Lifeboat to run a pump out to us? We're only 25 miles off Glen Head)
Deep Harvester Malin Head - R118 will be over your location in 55 minutes, expect to see the CASA topcover before that, please standby for their transmission. Arranmore RNLI have been tasked and should be with you in 90 minutes with equipment.
(Ah nooooo! We just need a pump - that's a wild fuss - we'll be a laughing stock)

It's fun trying to guess the silent half of the chat

All CG stations maintain a listening brief on Ch16 and with one exception should be called on that for either routine or emergency traffic. Routine traffic (save for radio checks which are conducted briefly on Ch16) will then be switched to working channel (Portland CG - our local one - invariably designate Ch73 but cannot be reached initially on that channel).

The exception to the above is Solent CG which because of the amount of traffic in their area also maintains a listening brief on Ch67 which should be used directly for all routine traffic. Emergency traffic for Solent CG remains on 16.

Good idea but one question:

With my Icom 603 to transmit an individual call, I have to input the recipient mmsi or find it in the directory, then I have to select a channel for the following voice call then send the dsc.

So which channel should you use?

I would suggest stick to 16, if its non urgent they will tell you where to go (in a nice way).

If they are stupid busy they will tell you were to go in a more direct way....

They will be ok considering you are nearly french, but less understanding if you use 16 everyday for a radio check.

Any clear (check before you send the DSC) working channel: 06, 08, 72 and 77 are the usual ones for general ship to ship.

I've been reading up the same trying to work out how to do this on my own newish Icom 505. The extract from the manual below for an individual call looks like I can't specify e.g. Ch 67 as the goto channel which would be really useful. (But I haven't played in anger yet).

"Rotate [CHANNEL] to select a desired intership channel,
push [CHANNEL•ENTER].

(The diag gives the impression that rotating [Channel] simply scrolls through the preset list below).

• Intership channels are already preset into the transceiver in recommended
order:
08
69
77
06"

The manual doesn't really cover ship to shore (CG) situations.
