RedactedNarrative: An underway vessel was inadvertently maneuvered into an anchored vessel at the conclusion of the 4th of July fireworks show in Destin Harbor. At the conclusion of the 4th of July fireworks show in the Destin Pass at approximately 2130 hours, I observed V1 attempt to reposition itself amongst other vessel traffic which was already at anchor.  
  
  V2 was at anchor nearby and had been for the duration of the fireworks show, whereas V1 was continually in motion and could be seen struggling to maintain position due to the outgoing tidal current.  Just prior to the accident, V1's bow was pointing south and the operator maneuvered the vessel, swinging its bow to the east and then north in an effort to place the bow headfirst into the current.  While doing so, V1's bow swept over the bow of V2, which was stationary, anchored and properly displaying all navigation lights.  V1's bow, which was higher than V2's from the waterline, crushed a large section of the stainless steel bow rail on V2.  The occupants on V2's bow had just completed watching the fireworks show and were able to retreat to safety without being harmed by V1's actions. Op of V1 stated the throttle controls slipped and that he had never experienced an event such as that before.
