RedactedNarrative: On June 30, 2017 at approximately 6:00 P.M. a 57' yacht (US doc # 110460) named "Off the Court", powered by diesel engines with remote steering (Vessel #1), was cruising eastbound on the ICW at approximately 11.5  knots causing large waves, with a total of two people onboard.  
  
  At that time a 14' aluminum olive green Landeau flat boat, LA 9472 ES, with a 25 HP Evinrude tiller steering (vessel #2), was tied-up to several Cypress knees along the northern shore of the ICW, with two people onboard whom were fishing.  
  
  Vessel #2 was positioned very close to the shoreline between two cluster of trees over the water that restricted other vessels traveling to ICW to immediately observe Vessel #2.  The two people onboard Vessel #2 observed Vessel #1 getting closer to their location while still causing large wakes, so they began waving their arms and even sounded an air horn. The operator of Vessel #1 heard the horn, looked around and observed Vessel #2 in the trees directly off the port side.  
  
  Operator1 shut down the engines to idle, passed Vessel #2 then began cruising again.  The force of the waves caused by Vessel #1 began to rock Vessel #2, causing an occupant whom was on a a makeshift seat approximately 6 inches above the floor of Vessel #2 to fall overboard  port side into the water.  He was retrieved from the water and claimed he had neck and back pain, due to hitting Cypress knees in the water.  He was removed from Vessel #2 by ambulance personnel and brought to a local hospital for further care.  No PFD's were donned or used by any parties involved.  Drugs and/or alcohol are not suspected in this incident.
