Coast Guard Petty Officer First Class Mariana O'Leary says they suspect the man was very drunk.
The Coast Guard says a boater reported seeing an unconscious man floating well offshore. The Coast Guard and a Clearwater Fire Rescue unit responded and found the man, still unconscious and wearing a life jacket.
He eventually woke up and was checked by paramedics at a Coast Guard station.
O'Leary said the Pinellas County Sheriff's Office will investigate the incident.
