The operator of Vessel 1 was loading the boat onto the trailer at the boat ramp.  The husband of the operator was standing on the trailer waiting to secure the boat to the trailer.  The operator inadvertently used full throttle instead of retarding the power.  The boat surged forward and struck the husband and stop for the boat which holds the winch on the trailer.  The husband was ejected off of the trailer and landed on his back in very shallow water on the pavement.  The husband was knocked unconscious.  An ambulance was called for the husband, he was transported to Union Hospital in Terre Haute, Indiana.  The husband sustained a broken clavicle and multiple bruises and contusions on his body.  The stop for the boat on the front of the trailer was sheared off the trailer.
