RedactedNarrative: At approximately 1515 hours on Saturday, September 26, 2015, I, Off. was on routine patrol on the Patapsco River on NRP vessel 140 in the area of the Key Boperator when I hear a call for a vessel in distress. The hailing vessel, identified as Sailing Vessel Mangas, was located about 100 yards off of my starboard bow. The operator of Mangas reported that they had rescued a person from a sunken boat in the area of the Key Boperator. I came alongside SV Mangas and confirmed they had rescued the sole occupant of the sunken boat.
  
  I transferred Operator from the sailing vessel to my patrol boat and started evaluating his condition. Operator stated he did not need medical attention several times. I observed no injuries and Operator showed no signs of hypothermia. I advised USCG and other responding agencies of the sunken boat’s approximate location. Operator described his boat as a 14’ Jon boat with a 9.9 HP motor.
  
  I transported Operator to Merritt Beach Park where Operator had launched his boat and left his truck. When we arrived at the launch ramp, I interviewed Operator and took a written statement. Operator told me that he was traveling North under the Key Bridge towards Bear Creek when the waves started coming over his bow and swamped his boat. As Operator’s boat sank, he grabbed a life jacket and held on to it and floated until he was picked up. Operator also told me that several power boats passed him while he was floating under the Key Bridge.
  
  I walked with Operator to his truck and made sure he was able to start the truck before I returned to my patrol boat.
  
  I returned Baltimore Inner Harbor and located the Sailing Vessel Mangas at Anchorage Marina and spoke to the owner of Mangas. Also, there were three passengers on Mangas. Subject told me they were under sail when they heard someone yelling in the area of the Key Bridge. Subject said he saw Operator floating in the water holding onto an orange lifejacket. The Subject and his passengers assisted Operator onto Mangas. Subject then called the US Coast Guard for assistance on the VHF marine radio.
  
  Incident occurred in Baltimore County..
