Safe Diving Practices V
VHF radio
VHF radios are a valuable aid to safety at sea and, together with suitable waterproof housings, are frequently used in small boats.
Radio installations should be covered by a Ship’s Radio Licence and, under normal circumstances, should only be used by, or under the supervision of, someone who holds an appropriate Certificate of Competence.
It is an offence to use Marine VHF radio from the land, (unless it is a registered land station) so your shore party is not allowed to use one.
