RedactedNarrative: On July 4th, 2021, at around 3:37 P.M., Maryland Natural Resources Police, received a call for a vessel taking on water in the area of Rock Creek, Pasadena, Anne Arundel Co, MD. Upon arriving at the scene, at about 3:45 P.M., I observed a red pontoon boat partially submerged with the starboard pontoon underwater. The vessel had struck a submerged piling causing the starboard pontoon to fill with water and sink.  The vessel was located south of the main channel for Rock Creek, between the green marker "3" and the Maryland Yacht Club. The GPS coordinates were N 39.15437, W 076.50381.  
      The conditions at the time were sunny with clear visibility, 82 degrees Fahrenheit air temperature, with a light wind (6 mph west-southwest). The water temperature was 78.4 degrees Fahrenheit with a depth of 9.7ft at the point of impact. The boat traffic in the area was moderate to high traffic due to the holiday. The tide was going out at about 0.8ft.
      The vessel was a 2018 Bentley Acquisition LLC 240 Cruise RE 24ft, MD registration 4605DB. The registered owner is OWNER 1. She was on board, but not operating the vessel at the time of the accident. The operator of the vessel was asked about the cause of the accident. OPERATOR 1 stated that they were eating lunch while leaving Rock Creek. They were cruising slightly above idle (about 5 mph) when they struck an underwater obstruction. OPERATOR 1 stated that he has extensive experience on the water (about 30 years), and has traveled into Rock Creek many times. The vessel was occupied by four adults and two dogs on board at the time of the accident, and no injuries occurred from the accident. Two other adults on board.    
  Occupants of the vessel were transported to Maryland Yacht Club to be picked up by a family member. No injuries occurred during this incident. The vessel was handled by TowBoat US and taken out of the water. All Star Marine of Middle River, MD, is performing the repairs to the vessel. It was learned, after speaking with the staff of All Star Marine, the total repair estimate for the damage was $23,812.81 for the replacement of both pontoons, a new lower unit for the engine, and a replacement swim ladder. The boat is insured through State Farm. 
  The accident was caused by operator inattention and an improper lookout while traveling outside of the marked channel. The area is marked on GPS for having underwater obstructions. Most people who travel this creek know the obstructions and avoid the area. No charges were issued to the operator of the vessel.
  All events occurred within Anne Arundel County, Maryland.
