RedactedNarrative: On 9/7/15 at approximately 2:40 PM ,I responded with Off. to Sinepuxent Bay off of Castaways Campground for a vessel taking on water. Upon arrival we observed a vessel aground on the shoal North of red marker#10.We removed two adult passengers and one child from the vessel and transported them to land. The owner stayed with the vessel and commercial Tow Boat responded to the scene and transported the vessel and owner to the commercial harbor Ocean City and the vessel was removed from the water.
  
  Operator stated that she was operating her vessel North bound in the channel North of the Verrazano bridge West 
  of the dredge equipment opposite red marker#16 when she struck an unknown submerged object which stopped her vessel.The passengers were thrown forward when the impact occurred but were not injured.The vessel immediately began taking on water and Operator continued North until the vessel was off of Castaways campground when the vessel ran aground.She then called for assistance.The Coast Guard and NRP responded.
  
  Investigation revealed that the vessel had struck a submerged dredge pipe that was unmarked.
  
  There were no injuries.
  
  I inspected the vessel after it was removed from the water and found that the hull had cracked fiberglass on the port side of the hull below the waterline,which was consistent with striking a submerged object.
  
  There were no charges filed.
  Investigation is complete.
  All events occurred in Worcester County,Maryland..
