Another thought: if a pre-launch check is required, BLM requires:
"Labels must be attached and legible. Approved jackets will have some or all of the following wording:
TYPE I, III, V
U.S. Coastguard approved
Approved for paddling, whitewater, kayaking, canoeing
For all Recreational Use
a proper-size Type I, III or V PFD (approved on the label for paddling, whitewater,
kayaking) for each member of the party.
Approved for all inland water uses"
Have seen numerous groups refused launch due to worn/inadequate/wrong size pfds
