RedactedNarrative: After reviewing statements from passengers, witnesses and the operator and observing the evidence at hand, it is believed by this Investigator that the follow occurred. On July 18, 2020 at approx. 10:30pm. Vessel 1 was being operated downstream by Operator 1. Operator 1 was operating her vessel on the correct side of the waterway (right of mid-channel) at an idle speed. Operator 1's vessel was also operating next to, and in the same direction of their friend's vessel (operated by Operator 2). Operator 1 and Operator 2 vessels were being passed by another vessel operated by Operator 3. All witnesses stated that Operator 3 was passing the other two vessels at a very slow speed. At this time, another vessel (vessel 2), believed to be a dark colored pontoon vessel, was traveling upstream. For unknown reasons, the operator of vessel 2 (unknown registration numbers) steered to port and collided with vessel 1 (Operator 1's vessel). Upon collision Occupant 1 and Operator 1 were ejected from the vessel and landed in the water. Occupant 1 was wearing a properly fitted PFD at the time of the incident but Operator 1 was not. Operator 2 jumped into the water and assisted Operator 1 and Occupant 1 back into their vessel. Vessel 1 was equipped with an emergency ignition safety switch and lanyard but Operator 1 was not wearing it. Vessel 2 was observed leaving the scene of the incident without rendering aid or providing any information of their vessel to the other party. This vessel is believed to be a dark colored pontoon vessel. Some of the witnesses stated that they believed it was a black, tri-hull pontoon vessel. All witnesses stated that all vessels were displaying proper navigation lights except for vessel 2 which was observed not displaying any lights. In addition to navigation lights, the vessels that were bowfishing (Operator 1 and Operator 2 vessels) were also displaying extremely bright white lights from the bow of their vessel. Occupant 1 and Operator 2 were injured as a result of the incident. Occupant 1 suffered a concussion and broken scapular. Operator 2 suffered a minor scrape on her leg. Occupant 1 and Operator 2 were treated at North Oaks Hospital in Hammond, LA. the night of the incident but were released early the next morning. Vessel 1 suffered rather significant damage to the bow (see photos). Alcohol was not suspected to be a factor in this incident, however it is unknown at this time the reason that vessel 2 fled the scene. No citations were issued, however this incident is still under investigation.
