To say this is coast guard approved is misleading at best. Pay attention to what I say next: you are required to have flares and this is not a substitute!! How do I know...the coast guard told me so--- two stations on long island. This is made to go on a life vest and is just an extra layer of insurance. Flares must be on board and not expired.
