RedactedNarrative: On August 15, 2020 at approximately 3:51 PM Vessel #1 a remote steered 19' SeaPro powered by a 150 HP Outboard was being operated by Operator 1 on Calcasieu River in Calcasieu Parish.  V1 was being occupied by its operator and two (2) passengers as well as towing two (2) occupants on an inflatable tube.  V1 was traveling north upstream on the left side of the river and approached a bend in the river.  Vessel #2 a remote steered 18' Chaparral operated by Operator 2 which was occupied by its operator and one (1) passenger was traveling south bound heading downstream and was completing the turn in the same bend as V1 on the right side of the river.    V1 traveling on the wrong side of the river was approaching V2.   In an attempt to avoid collision the operator V2 attempted to turn his vessel starboard but could not turn starboard enough to avoid collision due to the river bank.  V1 struck V2 on the port side of the vessel near the gunwale.   This caused the operator and passenger of V1 to be ejected from their vessel and into the water.    The passenger of V2 sustained serious bodily injury and was brought to Lake Charles Memorial Hospital.  The operator of V1 fled the scene after the collision.  The operator of V2 was able to identify the operator of V1.  Agents made contact with the operator of V1 Operator 1 at his residence, conducted a field sobriety test and determined that he was impaired (See Cpl's DWI report) and placed him in custody.  Operator 1 was arrested and charged for operating a vessel while intoxicated, first degree vehicular negligent injury, hit and run (vessel) and reckless operation of a vessel.   The only PFD's used were by the two occupants being towed by V1.    The contributing factors:   Reckless operation is the main contributing factor as operator1 was operating his vessel on the wrong side of the river as he was looking at the skiers, he was towing and not paying attention to where he was going.    The second factor is alcohol  as operator1 was impaired as he was operating V1.    The third factor is improper lookout.  According to the passenger of V2 and an eye witness as V1 approached V2 they could see that no one on board V1 was looking ahead but instead all looking backwards at the passengers being pulled on the tube.
