RedactedNarrative: According to operator1 he was idling through the marina, however as he neared his slip V1 appeared to have an issue with the computer system causing the engine power to increase without any input from the operator. 
  
  V1 accelerated uncontrollably as he attempted to stop the vessel with the engine throttles and emergency kill switch. These attempts were unsuccessful and V1 collided with a piling that separated V1’s slip from V2’s. 
  
  This impact caused V1 to veer towards V2. V1 continued forward scraping the piling on its starboard side until its bow collided with the bow of V2. During the collision, V1 sustained minor damage to the anchor roller and V2 sustained significant damage to the anchor roller and bow rail. No injuries were sustained during this incident.
