RedactedNarrative: On or about 7/1/2016 at 08:00 hours two subjects left from a cove just downstream from Norris Dam Marina in a pontoon boat rented from Norris Dam Marina, with Operator driving the boat.  Based on statements given by both Operator, and Occupant1 they headed upstream to Norris Dam Marina and then further upstream to Twin Cove Marina to buy beer.  It was after leaving Twin Cove Marina and heading back downstream that, sometime around 10 a.m, they struck and object in the water.  
  
  Occupant1 advises he does not know what they struck and was asleep at the time of the incident.  Operator also was unsure as to what they struck but stated that he thought it was a log or tree in the water.  Operator, after striking the unknown object, then operated the vessel back to the rental houseboat where the group was staying.  They arrived back at approximately 10:50 a.m.  
  
  Two people then took the vessel back to the marina and reported the collision.  Subject and Operator stated that they had been drinking that morning both prior to the incident as well as following the incident.  However, due to the time lapse between the incident, reporting, and contact with operator,  as well as the fact that the subjects had been drinking post collision, no FSTs nor BAC testing was administered.   Narrative is based on witness and or operator statements.
