RedactedNarrative: On 08/28/2021 at approximately 11:10 PM, I, Conservation Police Officer, was made aware of a boat accident by CPD Marine Unit that happened earlier in the day.
  
  On 08/29/2021, I contacted - Coast Yachts Manager. she advised me one of there memebers, was operating their rental boat and was struck by another watercraft, near the Chicago Locks on the riverside. They believes vessel is another rental boat owned by Yacht Charters. They provided me with a phone number.
  
  I contacted O2 and he advised me of the following: At approximately 7:45PM,  he was operating a waiting (Idle -Stationary) to enter the Chicago Locks from the riverside. "vessel" was located on The Good LIfe''s port-stern side. They slid between The V2 and another smaller boat to enter the lock. As V2 turned to their portside to pass, the stern of V2 struck the port swim platform of V1. O2 called and she advised them to wave them down and have someone give them a phone number. O2 yelled at someone on the boat to stop, a girl came out and asked him for his phone number. Someone called O2 phone and then hung up. 
  
  I provided O2 with my email and advised him to provide me with addtional information on the vessel, location, and passengers/witnesses on board. 
  
  08/29/2021, O2 sent me photos of the O2, damage O1, passenger information, and GPS location. O2 forgot to include his information. 
  
  On 09/05/2021, I sent him an email requesting the information. While on boat patrol on the Chicago River, I observed O1 underway and requested  the watercrafts information.Photos taken of the IL registration application and Rental License.
  
  09/07/2021, I contacted - Coast Manger, she advised she spoke with the captain of O1, . They stated to owner the accident was caused by O2. They advised the damage was approximately $2,500.00.  
  
  On 10/14/2021,  I contacted the operator, O1, of V1. O1 stated the following: 
  "On the night of 8/28/21 I was the captain of V1 75ft sunseeker. I was waiting to enter chicago locks from river side. As the light turned green for river side to enter, I started to move the boat into position. Slowly turning to port with some forward motion. As I was a boat length away from the locks, handful of small boats cut me off from my port and went under the bow of vintage. At which point I stopped the boat to avoid running them over. V1 was still turning to port w no forward or reverse momentum. Fourwinns was crowding me from the stern, perhaps to over take me on my starboard side between vintage and lock wall. At which point my swim platform collided with fourwinns swimplatform. Fourwinns should have not been so close to my stern as I had no space to maneuver. He also should not have started to go between the wall and vintage as the boat was still turning to become parallel with the south wall. I believe the bow of fourwins was facing SW, vintage at the time of collision was facing almost E. I was avoiding a possible collision around my bow as small boats cut me off."
  
  There is no video available from the Chicago Locks due to technical issues with the cameras.
