RedactedNarrative: On 07/28/2018, at approximately 1950, Operator was operating PWC (VA 9613 BE) on Smith Mountain Lake with his wife sitting as a spotter on the back of the PWC to watch their 14 year old child on the attached tube. Upon take off, Occupant was holding on to the handle bars of a Tie-Rod that was mounted to the back of the PWC. As the rope from the Tie-Rod attached to the tube extended, Occupant's right hand suddenly became tangled with the rope, resulting in an amputation of her middle finger just below the nail line. Occupant was transported to Roanoke Memorial and treated for the injury.
