RedactedNarrative: According to the rental facility they advised the renter (passenger 2) that the tube was tied to the fencing of the pontoon to keep it secure while motoring and further advised that they would need to remove it and secure to the tow eye when tubing. 
  
  According to the renter and occupants they were never informed of this so they began tubing with the tube still tied to the railing.  V1's railing and canopy were subsequently pulled off v1 and damaged.
  
  By the time the investigating officer arrived many of the passengers had left the scene and the renter was unable to provide dobs and addresses.
