When is a USCG-approved PFD considered not serviceable?

Answer 1

Serviceability means that fastening hardware is not broken and operates correctly, the webbing or straps are not ripped torn or missing. Fabric tears have not resulted in loss of buoyant material and that the buoyant material has not hardened or been contaminated by oil or other liquids. The flotation device must be structurally sound and free of rotted or corroded components. I would also personally take it as far as saying the PFD must fit properly and be appropriate for the intended use. It is also important to keep them readily accessible -I know some one that received a ticket for having the PFD's stored under the bow and not in a place where they could be quickly grabbed in an accident. I think most if not all states also require children under the age of 12 to wear a PFD at all times when the boat is in motion (for powerboats at least).
