RedactedNarrative: V1 heading North in the ICW, Lemon Bay.  V1 struck sandbar West of ICW, South of green marker 41.  Subject on V1 fell and was injured. 
  
  Operator told me that at approximately 1400 hours on 10/10/16, he was traveling North along the ICW in Lemon Bay, operating his vessel from the helm on the second deck.  Several vessels approached from the North idling through the slow speed zone (Forked Creek and Lemon Bay) but operating on the wrong side of the channel.  
  
  Operator was forced to the edge of the channel to avoid collision.  After the last vessel had passed and they were through the slow zone, Operator throttled up on his vessel and was on plane.  It was at this point that he admitted to looking back towards the vessels he had just passed.  At this same time, the marked channel veered slightly to the right (East).  
  
  His wife then noticed some vibration in the vessel as it began to run shallow and it then immediately struck a sandbar just outside the ICW. This caused Operator's vessel to come to an abrupt stop.  Operator was seated at the helm and was uninjured.  
  
  Occupant however was standing next to the helm at impact.  She was thrown from her feet and fell forward down an open hatch over which some steps led to the lower deck.  Operator quickly responded to her aid.  He then called Boat US for help.  Boat US then offered to contact Coast Guard and local first responders for help.  Occupant's injuries.  
  
  She was diagnosed with a head injury (concussion), broken left wrist (radial) and a fractured left thumb.  ;
