Operator stated that he was in the process of leaving a slip.  He had backed out, just pushed off a piling at the port stern, and returned to the helm.  While engaging the throttle into forward, the operator overcame a rough spot in the throttle and inadvertently pushed the throttle all the way forward.  The vessel response caused him to turn the wheel to starboard.  The vessel turned hard starboard, and as it rose in the bow in response to full throttle, the bow struck a dock just under the rub rail.  The vessel climbed up the dock, heeled on its stern, and eventually flipped over on itself.  The operator jumped from the vessel before it turned over on itself, uninjured.
