RedactedNarrative: On September 5th 2019 at around 1645 hours Operator1 was operating a 53 foot 2018 Harbor Cottage Houseboat rented through Lee's Ford Marina in the area of Jack's Branch on Lake Cumberland.  Operator1 pulled into an area densely populated with other boats.  As he was attempting to moor alongside several other houseboats his vessel began to drift near some other boats.  As his houseboat near the other boats he accelerated into forward gear causing the rear of his houseboat to make contact with a swim pad and then a 2013 Regal runabout that was not occupied at the time and that was moored to the port side near the stern on a rental houseboat.  As Operator1 continued steering the port side of the houseboat he was operating then struck a slide and rear deck of a 2003 model 73 foot long Horizon Yauchts houseboat rented from Beaver Creek Resort already moored to the shoreline.
  
  Officer conducted SFSTs on the operator of vessel 1 and it was determined he was not impaired.  There were no injuries reported.  
  
  Damage Assessment
  
  Vessel 1 2018 53' Harbor Cottage Houseboat 
  Vessel 1 sustained a busted port side window from impacting the slide of vessel 3 in that area.  Vessel 1 also had a rear porch post torn down from impacting the slide of vessel 3.
  
  Vessel 2 2013 24' Regal, OH-1836-FH
  Vessel 2 sustained some chipped fiberglass on it's swim platform from the rear deck of vessel 1 striking it.  That damage is around 2 by 3 inches.  
  
  Vessel 3 2003 73' Horizon Yaucht, Beaver Creek Resort "THE MARQUISE 61" Doc # 1142606
  Vessel 3 sustained a tear in the slide around 6 inches long.  Vessel 3 also had the slide support post torn out from the rear roof area and suffered bending to the aluminum support post.  Vessel 3 also had it's swim ladder broken in the area beside a weld.  The rear deck also appeared to be bent inward and upward in an area around 1 foot by 1 foot near the base of the slide support.         
  
  Conclusions
   
  Operator of vessel 1 was not experienced enough with the vessel 1 to attempt to maneuver it in a high traffic area.  The lack of experience with the vessel led to the operator not being able to recover as the rear of the vessel made contact with the swim pad and vessel 2.  Instead of altering course and applying reverse to slow vessel the operator overcorrected and applied forward with too much steering input which then led to the bow of vessel 1 making contact as well.  Had the operator of vessel 1 altered course early enough he could have moored the vessel successfully.
