RedactedNarrative: A subject was operating a sail boat proceeding south in Taylor Creek, hit an underwater obstruction which caused a passenger in the boat to fall resulting in an injury. I spoke to OP1 who told me he was operating the sail boat with the motor in Taylor Creek when he hit a submerged object which completely stopped his boat.  He stated that when the boat stopped his passenger fell from the deck through an open door into the cabin head first and struck the floor of the cabin injuring himself.  Op1 stated he then dialed 911.  He said he could not get his boat off of the underwater object to get Victim to shore so Okeechobee County Emergency Medical Services (EMS)  had to come to his aid by boat.  OP1 advised that victim was taken ashore by EMS then transported to the hospital.; Victim fell in the boat and received a spinal injury. Victim recovered the use of his extremities and It was determined that the injury was not serious.
