Wearing a lifejacket is compulsory in recreational aviation during maritime overflights.
If the regulations simply require its presence on board the aircraft for all occupants, it is more than strongly advised to put it on before departure...
I do not see myself indeed, unfolding it during an engine failure while managing the plane and the distress call ;-)
C'est cela ... oui, Cessna oui !
