Generally speaking, in coastal sailing, we are not obliged to have a VHF on board. It is from the semi-offshore (beyond 6 miles from a shelter) that this equipment becomes mandatory. However, a VHF is a main safety equipment. However, things are not clear about its use!
In fact, we have searched in the texts, the division 240, the SOLAS, the RIPAM and all the texts that govern our practice, nothing appears concerning the practice of pleasure boating by amateurs.
We contacted the authority in charge of the management of radioelectric means: the ANFR (Agence Nationale des Fréquences) to try to obtain a clear answer. Our interlocutor, Jean-Louis Schmitz explains: " For commercial vessels, the Channel 16 watchkeeping requirement is found in SOLAS and MSC 131(75)"
No professional, no obligation?
Since we are not professionals, we are not affected by this measure? Things are not as clear as that. This is what the ANFR explains to us: " For recreational vessels (which are not subject to the SOLAS Convention), this is a recommendation of the MSC circular 803. An evolution of this circular is underway. The draft evolution has been validated by NCSR8 and will be presented to MSC 105 in early 2022. "
A question of logic
So things are becoming a little clearer. Currently, the VHF equipment installed on board is not constrained. In principle, from the mid-shore navigation (more than 6 miles from a shelter), having a VHF in the box is enough to be in compliance with Division 240. Obviously, this is not our recommendation! Logic and the desire to be able to help others, lead us to turn on the VHF and leave it on standby on 16.
Changes in sight
As explained by the ANFR, things are changing. The next revision of the rules for radio communication at sea will probably force us to maintain a constant watch on Channel 16, once we are equipped.

It is extremely likely, although we do not yet have official confirmation, that VHF equipment, at least portable, will be made mandatory for coastal armament. This would represent the logical extension of such a collective safety measure.
