Injured had been tubing behind vessel when the line went slack and he jumped off as the vessel causing injury.  The line apparently wrapped around his leg dragging him under.  Operator stopped vessel and retrieved injured from the water.  I witness from shore thought the operator was too close to shore, reversed directions and then he heard yelling.  The investigator suspected that the operator was traveling to close to shore but could not collaborate the witness information from shore with the information received from operator, injured and 3rd person on board.  A citation was given for lack of safety equipment on board.  Insufficient # of PFD's and a warning for a fire extinguisher that was not in serviceable condition.
