It's one thing being able to use the VHF in the confort of the classroom or in a sunday day out in the Solent, with light weterly wind no waves, calm as you like ...... and being ankle deep in water, rods everywhere, lines, kids running around screaming and you shouting for the missus to make sure the kids have the lifejacket (they should have already, but just make sure) and they know how to use the pull string shall the auto fail to work. and worryingly, is the battery clear of the water?
I suppose if we practise the drill time and time again then it will make the actual event much less exciting (or panicking ....lol)
