RedactedNarrative: Operator left Boom #5, Boathouse in Red Wing, operating WC #1. Operator #1 added gas to the fuel tank from a canister inside the boathouse prior to leaving. Watercraft #1 was northbound on the river. They were at the end of the northern No Wake Zone in Bay Point, in the middle of the channel. WC #1 has a manual trim; the pin on the trip was in the second hole up from the bottom. Operator #1 turned off the motor and went to lift the motor and place the pin for the trim. Operator #1 stated they leave it up when stored in the boathouse to keep the motor out of the water. Operator #1 looked downstream and didn't see anything. A passenger on WC #1 told Operator #1 that a barge was coming.
  
  Operator #1 had the motor back in the water. The motor wouldn't start. Watercraft #1 floated into the port side of the barge towed by WC #2. WC #1's impact was on the bow, port side. Watercraft #1 overturned and all occupants were out of the boat and in the river. Operator #1 was able to locate three of the juvenile passengers, but was unable to find a 5-year-old boy. Operator #1 thought the boy was underneath the overturned boat. A good Samaritan towed WC #1 to Red Wing Marina. When WC #1 was to the dock, the good Samaritan noticed a child's shoe in the boat. The good Samaritan pulled the boy out of the boat and CPR was started. The victim was not breathing and was taken by Red Wing ambulance to the hospital in Red Wing, where he was then flown to Rochester.
  
  Alcohol was not a factor. Lifejackets were being worn. There was some damage to WC #1.
