RedactedNarrative: Vessel 1(V1) was traveling southwest on Fish River.  V1''s operator stated that as he was negotiating a curve to the right, he was attempting to avoid a dock by traveling further to left and did not notice a construction vessel(V2) that was to his left.  
  
  Operator went on to state that as he continued to maneuver to the left, his son, that was tubing behind his vessel, swung too wide and struck the engine of the construction vessel.  Operator went on to state that V2 was in the middle of the river which is why his son struck the vessel and he was unable to avoid the collision.  A witness stated that V2 was well out of the path of any vessel traffic and that V1 had traveled through the area multiple times that day, and was aware of the construction crew''s presence. 
  
  As the result of careless operation and inattention, V1''s tuber struck the engine of V2.  V1''s tuber sustained a broken leg and lacerations as a result of the accident.  V1 was also properly equipped with a mirror to observe the tuber in tow.  V2 did not sustain any damage.  Operator went on to state that he did not initially notify the Alabama Law Enforcement Agency due to emergency circumstances at the time of the accident.
