RedactedNarrative: On Friday, April 23, 2021, at approximately 1559 hours, Maryland Natural Resources Police, was dispatched to a vessel in distress call for service. An individual made a mayday distress call over VHF channel 16 and advised that his vessel was sinking and his starboard motor was smoking at the mouth of Herring Bay on the Chesapeake Bay, located in Anne Arundel County, MD.
          Officers arrived on the scene at 1631 hours, aboard patrol vessel NRP144. At that time the vessel was completely submerged and both individuals were recovered from the water. The two occupants and their dog were previously recovered by the North Beach Fire Department Fireboat and the individuals were subsequently tended to by medical personnel. Both individuals were given blankets to help with the cold water temperatures that they experienced.
          The vessel information/description of the vessel that sank is as follows:
             2007 35'3" EXPRESS CAROLINA CLASSIC
                  HIN: CAR35104J607
                  Vessel Name: Sirens Song
                  USCG DOCUMENTATION #: 1193903
                  EXPIRATION: 12/31/2022
                  Hull Color: Navy Blue
          The two occupants of the vessel were identified as: OPERATOR 1 and PASSENGER 1
          The North Beach Fireboat notified all units on the scene that they were going to be transporting both individuals for further evaluation to Herrington Harbor South Marina, located at 7149 Lake Shore Drive, North Beach, MD 20714. Officers subsequently responded to Herrington Harbor South Marina. Upon our arrival, OPERATOR 1 and PASSENGER 1 were being warmed up in an ambulance. MD NRP, met us at this same location to gather further vessel and personal information as provided above from both individuals. After about 15 minutes in the ambulance, OPERATOR 1 and PASSENGER 1 declined medical treatment and arranged to be taken back to the Herrington Harbor North Marina, just a few miles away.
          Prior to their departure, Officers, met with OPERATOR 1 to gather information on the incident. He advised that they had a 92-degree heading, heading in an east/northeast direction, at around 20 knots. He was passing the Green '1' marker, located off of Holland Point in the Herring Bay, when he noticed that the vessel was smoking very heavily from the starboard exhaust. OPERATOR 1 described it as, "very heavy black smoke." He then looked into the engine compartment where he realized there was a large amount of water entering the bilge and engine compartment area. OPERATOR 1 explained the smoke got worse and he did not want to look into the engine compartment in fear of causing a larger fire. OPERATOR 1 subsequently called out a mayday on VHF marine channel 16. Both he and his wife put on Type I PFDs. OPERATOR 1 advised that he shot off 3 individual flare distress signals prior to jumping into the water with his wife and dog. A good Samaritan arrived at the scene to help rescue OPERATOR 1 and PASSENGER 1. There was no identifying information provided regarding the Good Samaritan. The Good Samaritan was able to get PASSENGER 1 and her dog in their vessel. At that time, the North Beach fireboat arrived on the scene and was able to rescue OPERATOR 1 from the water. The Good Samaritan vessel transferred PASSENGER 1 and their dog to the fireboat where they began warming up both individuals and their dog. By this time the vessel was completely submerged and an exact location was unknown. OPERATOR 1 and PASSENGER 1 were then transported back to Herrington Harbor South Marina as explained above.
  
          Anne Arundel County Fireboat 19 remained in the area of where the vessel sank. They were able to locate a possible location with their side scan sonar. The approximate GPS coordinates of the vessel  were recorded as N 38 degrees 45.215'  W -76 degrees 28.190'. These coordinates were forwarded to OPERATOR 1 for recovery operations by TowBoat. The coordinates were also given to the United States Coast Guard (USCG) in order to broadcast a PonPon across marine channel 16 for a notice to mariners. The vessel is worth approximately $250,000. OPERATOR 1 advised that he contacted his insurance company, Chubb Insurance, and notified TowBoat of the situation. OPERATOR 1 stated that he would update me when Towboat plans to go out to assess the situation and attempt to lift the boat from the bottom. 
  
          On Tuesday, April 27, 2021, I made contact with OPERATOR 1 for an update on the situation. He advised that TowBoat has spent the past two days performing search patterns in hopes of locating the vessel, but has not had any luck doing so. I also received a call from a surveyor who was hired by Chubb Insurance. He advised that a USCG vessel would be assisting in the search for the vessel. As of the date above, the vessel still has not been located or recovered. At this point in time, the vessel is considered a complete loss.
  
  All events occurred in Anne Arundel County, MD.
