RedactedNarrative: Operator launched V1 and drove a short distance to the boat dock and waited for his passenger (son) to park the vehicle. 
  
  When the passenger arrived, they noticed V1 taking on water and realized they forgot to put the plug in. The passenger then went to retrieve the vehicle and back it down the ramp so they could load V1 onto it but the operator of V1 never showed up. 
  
  The passenger then went back to the dock to find V1 capsized.  A wrecker service towed V1 back to the boat ramp where it was loaded onto the trailer.
