RedactedNarrative: On 08/17/22 at approximately 5:54 P.M., Maryland Natural Resources Police responded for a vessel taking on water in the area of Herring Bay near Herrington Harbour South Marina, North Beach, MD. Upon arriving on scene I observed the Calvert County Fireboat side-towing the vessel in question into Herrington Harbour South. The vessel would be fully identified as 27' Regal Marine, white in color, bearing MD vessel registration. I followed the Calvert County Fireboat into Herrington Harbour South and met with the owner of the Regal who would be fully identified.  Owner advised that he was accompanied by his wife, and three children aboard the Regal. Owner advised that all members aboard the Regal were accounted for and no injuries were sustained. 
  
      Owner stated that he departed Herrington Harbour South at approximately 5:30 P.M. and cruised the area of Herring Bay for approximately 10-15 minutes. After approximately 10-15 minutes, Owner decided to return to Herrington Harbour South. Owner stated he was traveling at a speed of approximately 20 knots when the Regal suddenly lost power and abruptly slowed to approximately 5 knots. Owner immediately throttled down and observed smoke coming out of the engine compartment. Owner shut the engines off completely, advised the passengers to put on life jackets, and called 911. While waiting for help, Owner checked the engine compartment and observed that the engine compartment was halfway flooded with water. Owner observed that the water was entering the engine compartment from a crack in the port side engine exhaust manifold. It was at this time that the Calvert County Fire Department arrived on scene and utilized an external bilge pump. The Regal was then towed to Herrington Harbour South where U.S. Coast Guard Personnel were able to place wooden wedges around the exhaust manifold to restrict the water that was flooding the engine compartment. 
  
      Owner stated that before fire personnel were able to utilize the bilge pump, the engine compartment was approximately halfway filled with water. Owner stated that the Regal was equipped with two Volvo Penta gasoline engines that he estimated to be approximately $15,000 each. Owner speculated that both engines suffered significant damage due to being partially submerged from the water that flooded the engine compartment. 
  
      Approximately 45 minutes later, Tow. Boat U.S. arrived on scene and towed the Regal to Rod and Reel Marina in Chesapeake Beach where it was hauled out of the water and placed on a trailer for safekeeping. 
  
      The accident resulted in property damage only; no injuries were sustained.
  
      This case is considered closed and all events occurred in Anne Arundel County, MD.
