I assumed that was the case but wondered if there was some other process happening like they were alongside and shouting? Coz I cant see why they wouldn't be able to transmit to Solent from Ryde. But last night I couldn't hear solent transmit an MSI notice on 16 at Ryde but could hear Portland.The distressed boat must have had a VHF as RedKite was relaying info. In fact RedKite began by asking Solent CG if they had picked up the Mayday. At one point Solent cg asked RedKite to check if the distress boat had a mobile phone and asked them to dial 999 and ask for the Coastguard! We could only hear RedKite and Solent cg.
It should be a routine part of the SRC, certainly has been since DSC because there is a risk of relaying wrong and creating a second apparent incident.Ok, at the risk of appearing a bit dim, how does a relay get started?
I've never heard one in operation so am in the dark.
Assuming the boat in distress puts out a call on C16 but gets no reply, what happens next.
I can't remember this bring covered on my SR VHF course.
So the normal practice is to wait 3 to 5 minutes for a response. If it was a DSC alert the DSC set will repeat the alert at that point (unless the boat sank). You need to use some common sense - so if you are in the middle of the North Sea and a boat to the West of you transmits a MayDay it is more likely they hit a shore station than you will. If you hear them on a one sided conversation you know they hit something with their signal. That said if they get no response you might be the only boat in range.
Once you have decided that you need to Relay someone's MayDay you transmit as follows:
CH70 - DSC Urgency (not distress) call.
Retune CH16 and voice transmit:
"MAYDAY RELAY, MAYDAY RELAY, MAYDAY RELAY
THIS IS [YOUR MMSI], [YOUR VESSEL NAME] [YOUR VESSEL NAME] [YOUR VESSEL NAME], [YOUR CALLSIGN]
**Would be normal to take a short breather here - count to 3 in your head - keep the PTT depressed**
RECEIVED THE FOLLOWING MAYDAY FROM (MMSI of the vessel in distress), (Name of the vessel in distress), (Call sign of the vessel in distress)
MESSAGE BEGINS
(message received from vessel in distress or details of the distress)
MESSAGE ENDS
OVER
Await a response.
Your callsign will then be amended to something like "RELAY [Vessel Name]" So you are likely to get a response of
"RELAY [Your Vessel Name] this is Solent Coast Guard, we have received your mayday relay for [vessel name in distress]."
There are three things that you can basically get wrong:
1. Relaying a message which has already been received. While in its self not a problem it blocks 16 for further info which may be needed.
2. Hitting the DSC Distress Button to Relay - resulting in your vessel also appearing to be in distress. Search resources sent to wrong place etc
3. Messing with the message content. i.e. rewording what they said. That said in the Solent you'd rarely expect to do a Mayday Relay so you may not have written down their message and then 5 minutes later need to repeat it.
Yeh I fully expected the Lee mast to be receivable in Ryde - it normally is.Solent's aerials are Newhaven, Selsey, Lee, Boniface Down, Needles.
Portland's (well, till 15 Sept anyway then they close) are Hengistbury, Nine Barrow Down (looks back into Poole Harbour, a new one), St Albans Hd, Portland (Grove), Beer Head.
Portland's masts will all still function as before - just someone in a different office is talking to them. You can receive Portland in Ryde!
Surprising that AIS is higher than Ch16.
Where is Ch70?

I thought 70 was at the top followed by 16 followed by the others (not sure where AIS is). Although they can swap them over. Most dont have 67 open all the time but I *thought* that because solent did they actually had an extra aerial for it rather than limiting their access to others...
