While launching Vessel 1, the Operator avoided striking the dock behind Vessel 1 by immediately putting the throttle forward after entering the water.  This action propelled Vessel 1 toward a cement wall at the ramp.  The Operator then attempted to reach out toward the wall to stop the forward momentum of Vessel 1 and thereby avoid collision with the wall.  In the process of this action, the Operator sustained a back injury.  Emergency Services were contacted and arrived on scene, transporting the Operator/Victim to Southeastern Medical for treatment.
