RedactedNarrative: Friends decided to rent 2 pontoon vessels and were floating on the lake.  Operator noticed her vessel was drifting toward the sandbar so she started the engine and put the throttle in forward to move it.  
  
  She did not realize there were people behind the vessel and when she went to move it, two people became injured. 
  Operator was issued a violation notice for negligent operation and failure to report a boat accident.  It was the 1st time she operated a vessel.  She did not look behind the vessel before she backed up or confirmed if her friends were on the boat or in the water.  In a later interview she admitted to drinking 2 alcohol beverages but at the scene the officer did note alcohol beverages of the vessel but she did not appear to be impaired at the time.
