PFD Required???

[UCFKiteSurfer]

I was kite surfing in Titusville last Friday and I was stopped by the Florida Fish and Wildlife. They told me that it was illegal to kite surf while not wearing a life jacket. The guy said that whenever you are on plain you must wear a life jacket. This sounded crazy to me because I think I’ve seen maybe one or two people wear a PFD while kitesurfing or wind surfing and I’ve never seen a surfer wear one. Is this true or was this guy just borded and felt like hassling me? He told me that he wouldn’t write me a ticket but another officer might.
