I often fish on my own and just usually carry out a channel 16 radio check. Fishing at night is a bit different since well meaning people, seeing your lights from shore, sometimes phone the coastguard to say there is a small boat out there etc. So if fishing into the dark I always tell the coastguard and let them know when I get back.
One question I'd like to raise is what is the usual channel for small boat to boat communications in the north east? I think it is channel 8 but I'm told channel 10 is now favoured?
