I think this has came up before. If I understand correctly the law requires you still have to have a conventional type I, II or III PFD in the boat for every passenger, even if you use inflatables. The reason being if an inflatable is activated for whatever reason (they can inflate accidently) then from that point on they are useless and you would not have a useable PFD onboard for every person which is a violation of the law.


Am I correct???
