RedactedNarrative: On July 28th, 2018 at approximately 9:45am Rangers were dispatched to Bullfrog Marina for a vessel accident on "P" dock at slip. Ranger began the initial investigation at slip and identified both vessels and parties involved.
  
  I contacted OPERATOR1, who told me that she noticed the houseboat "EMERALD BAY" reversing out of slip. EMERALD BAY continued to reverse and hit the stern of the FORGOTTEN CANYON which ripped off the slide and broke the stern port light on the FORGOTTEN CANYON. OPERATOR1 mentioned that EMERALD BAY started moving forward and hit the stern of another houseboat in slip before docking on "H" dock. Ranger  took photos of the slide and of the spotlight damages. I performed a vessel inspection, and OPERATOR1 informed me that no one was injured during the incident. I gave OPERATOR1 a card with my information to send me the vessels current insurance.
  
  I then contacted the owners of the house boat in slip, which didn't want a report on any of their damages.
  
  Ranger and I, then proceeded to talk with the operator of "EMERALD BAY" that was in slip before the incident, now docked at the end of "H" dock. We identified the operator. OPERATOR2 informed me that he started backing out of slip and noticed that the vessel was unable to turn to his port side and something seemed wrong with his starboard engine. OPERATOR2 informed me that he reversed into FORGOTTEN CANYON and saw his vessel rip the slide off EMERALD BAY's stern. OPERATOR2 informed me that he was then able to gain enough control to steer the vessel to where it was docked. OPERATOR2 also informed me that he called the last operator of the vessel and was told that they were having issues with the engines on their last trip and never reported it. I performed a vessel inspection, and OPERATOR2 informed me no one on his vessel was injured. I gave a card to OPERATOR2 to send me the vessels insurance.
  
  From my investigation and observations, EMERALD BAY had prior engine problems that should have been taken care of before leaving the dock. I believe OPERATOR2 did perform his best to avoid an incident but due to mechanical issues was unable to avoid it.
