RedactedNarrative: Accident involving a rental vessel vs fixed object (canyon wall/large rocks/shoreline), with capsizing and minor injury (laceration), suffered by juvenile passenger. Accident vessel: 2006 Champion Explorer rental vessel CF2, owned by Black Canyon River Adventures LLC (Willow Beach Marina). 
   
  The vessel was operated by Operator1 south from Willow Beach on the Lower Colorado River. Operator1 stated while operating south he had stayed near center channel and was almost struck by another vessel coming around a bend. He stated upon operating back north to Willow Beach he decided to stay closer to the shoreline (AZ side of river), due to the earlier near miss. He stated the dog (K9), had got between him and the helm while crawling under his feet, and resulted in him in diverting his attention. He stated his brother (juvenile passenger), attempted to pull the dog back, and that is when he struck the shoreline. The point of impact was a large boulder with a flat angling surface towards the water. Impact angle of the vessel and shape of the boulder caused the vessel to travel upwards and roll back towards the water. This resulted in the two adults being ejected (female from the front of vessel), and the juvenile and dog being trapped temporarily underneath the vessel upon it landing back in the water upside down. Juvenile was able to swim out from under the vessel and the operator rescued the dog. All parties were able to safely get on shore and wave down individuals passing by on a PWC (reporting party to marina/did not remain onscene).
