I understand that inflatable PFDs are not considered as a PFD for 16 and under, but there is not a requirement for 13 and up to wear a PFD. If my 13 year old is wearing an inflatable PFD, but there is also a standard PFD available for him on the boat, does this meet the requirements? He wants to wear one while we fish, but gets so hot in a traditional PFD.
