RedactedNarrative: This is a single vessel incident. Alcohol was not a factor. 
  
  V1 was traveling west bound underneath Fleming Key Bridge. V1 was occupied by a single operator and 4 occupants. Operator failed to maintain a proper look out by not noticing Fleming Key Bridge was currently under repairs and is an active construction site. Fleming Key Bridge has been closed for transit by USCG until further notice. This has been broadcasted by USCG and is an active Notice to Mariners. 
  Operator of V1 attempted astern propulsion and back away from the bridge. This astern propulsion was not enought to counteract the tidal current flowing west bound. V1 struck the Fleming Key Bridge on its port side below the water line. V1 was taking on water. This strike cause structural damage to the stringer/ bulkhead of v1. This damage has been estimated by myself to be over $2,000.00. The operator of v1 was issued warnings for vioating a USCG Navigation Rule and Improper display of Registration Numbers.
