RedactedNarrative: Witness stated that she was on the aft deck of her houseboat which was berthed in slip 3A4, right next to O1. Witness stated she saw a rental houseboat with the number “3” on its side, traveling at almost a 45 degree angle through the main channel in the Antelope Point wakeless zone. The bow of the rental boat was facing towards the dock and there were people on the bow yelling that they had lost and engine and their steering wasn't responding. This caused the rental houseboat to come too close to the other houseboats that were berthed on the dock and eventually the rental houseboat hit its port bow on the stern of O2. Witness stated the impact was slow but did cause damage to the stern of O2. Witness took a picture of the rental vessel after they were able to successfully push away from the dock to avoid any further damage.
  
  On 8/6/2021, I boarded O2 and documented the damage to the vessel from the collision. I noted that there was a broken weld on the starboard most bumper rail and I was informed that the bumper rail that was on the port most side had to be replaced completely. There was a bend in the exhaust stack on the port side next to the top slide. I also observed damage to the top slide including a chunk of fiberglass missing from the bottom port side of the slide that was approximately 2”x3”. The top slide itself was slightly off center however I did not observe that any supports were pulled out of the body of the houseboat due to the collision. On the top of the top slide I notice white duct tape covering what I was told were cracks on either side of the slide extending from top to bottom on both sides.
  
  Individual estimated the cost to fix O2 was approximately $20,000.
