This book explains how to use a VHF radio on your boat. It covers licensing the boat and the operator, then takes you through each type of call, and its ‘standard procedure’. You can also call using Digital Selective Calling (DSC) and the book has photo sequences of how to do this. Probably the most important section is sending a Mayday- the nautical call for help.
This 2nd edition contains all relevant updates including; changes to Calling for Medical Advice and to the way Coastguards listen on Channel 16.
