RedactedNarrative: On 4/23/2019 at approximately 1715 hours, Operator along with his daughter and granddaughter were operating a 16' aluminum bass tracker in the Escambia Bay near the I-10 Bridge in Santa Rosa County Florida.  The operator’s daughter was sitting next to him on the port side of the vessel.  The Grand daughter was riding on the bow of the vessel.  Operator and Daughter were not wearing a life jacket.  Granddaughter was wearing a life jacket at the time of impact.
  
  My investigation revealed Operator was operating the vessel southwest underneath the I-10 bridge at approximately 25-30 mph. The weather was nice with good visibility. Light wind with calm seas. It appears Operator started his turn to the left immediately after coming under the bridge.  He continued traveling at the same rate of speed during the turn.  He was going southeast turning towards the northeast.  As he approached the bridge after the turn was near completed, he realized the vessel was not turning sharp enough to make the turn.  At which point the boat collided with the concrete piling.  At the point of impact, all three subjects were ejected from the vessel. 
  
  The vessel then straightened up due to impact and the bow of the vessel hit the second piling.  Both occupants of the vessel were run over by the vessel. It appears that Daughter was struck by the motor on her left shoulder causing a laceration and contusions to the same area.  Granddaughter was also struck by the vessel but was undetermined if the motor struck her.  She had a compound fracture to her right arm and a laceration to her right hand.  The operator did not sustain any injuries from the collision.  All three subjects were in the water for approximately 30 minutes till emergency crews arrived on-scene to assist.  All three subjects were taken to Sacred Heart hospital by Ambulance and treated for Hypothermia along with the above mentioned injures. 
  All subjects were released from the hospital after required treatment.
  
  The owner of the vessel was notified and stated to me he allowed Operator to use the vessel.  The owner does not have insurance on the vessel.
  
  Nothing further to add at this time.; GRANDDAUGHTER:Open compound fracture to right arm requiring surgery. Laceration requiring stitches to right hand. Treated for hypothermia.; OPERATOR:Being treated for Hypothemia at Sacred Heart Hospital.  Patient has previous leg amputation and has trouble swimming due to past injury.; daughter:Laceration and contusions from prop to left shoulder.  Also treated for Hypothermia
