RedactedNarrative: V1, with two people onboard, was pulling a tube with two other individuals when it hit its own wake causing the vessel to catch a chine and suddenly stop, ejecting both people onboard into the water. V1 continued driving in a circle around two of the individuals while the other two were able to get off the tube and swim to safety. 
  
  A good Samaritan on a personal watercraft was able to rescue the two individuals from inside the runaway vessels circle. After driving in a circle for approximately 5-10 minutes, the unmanned vessel struck a boat lift causing significant damage and continued on its route until finally striking the same dock, shutting down the motor and coming to a rest.
