RedactedNarrative: On August 11, 2022 I U.S. Park Ranger 1 was dispatched to the Antelope Point Marina for a vessel accident.  It was reported that one of the vessels had left the scene.  I arrived on scene at slip to houseboat and spoke to an Antelope Point Executive Services Employee who witnessed the accident.  Employee stated to me in person and in a written statement that a 75ft Wahweap rental houseboat (Vessel 1) struck the back of the houseboat (Vessel 2) and caused damage.
  
  I observed the damage located on Vessel 2 which was contained to the starboard side stern.  The only damage that I observed and that was reported was to Vessel 2's cleats and railings (see attached NPS photo log)
  
  I contacted Wahweap boat rentals and obtained the name of operator of Vessel 1 as V1 Operator.  V1 Operator to me over the phone and later in a witness statement that he was operating Vessel 1 in the Antelope Point Marina wakeless channel driving uplake when Vessel 1 lost engine power and caused him to drift uncontrolled into the stern of Vessel 2.  V1 Operator was then able to regain control of Vessel 1 and continue with no further issues.  V1 Operator proveded witness statements and a vessel accident form on August 15, 2022, to Ranger 2.  
  
  On August 12, 2022 I spoke to the owner of Vessel 2, V2 Owner.  I collected vessel information and completed and boat accident form.  V2 Owner stated the only damage to Vessel 2 was that was originally observed and documented.  V2 Owner estimated the damage to be approximately $4,000.00
  
  Based on the statements of witnesses, V1 Operator and the investigation, Vessel 1 (Houseboat T-6) operated by V1 Operator was at fault for the collision with Vessel 2 due to equipment/engine failure and operator inexperience.
