RedactedNarrative: At 1630 hours on 06/03/2018, Officer, Crawford State park ranger, responded to a report of a sinking boat. The resident stated that he had seen a boat in the water 3 or 4 docks north of his home. We walked down to his dock and from there I could see three men and a half sunk boat on the shore.
  Subjects told me that the boat had sunk. I went down to the dock where the boat was tied up to inspect it, and was met by the owner and the operator of the boat at the time of the incident. Subject told me that they were going down the lake when they heard a loud crack, and then water started coming into the boat from the floor. Subject told me that he was unsure of the cause of the noise and the water coming into the boat. I was looking at the boat and it did not appear that the boat was taking on any more water than was already in the boat. Subject2 went to the boat ramp to get his truck so they could get their equipment and gear picked up out of the boat and I went to put our patroll boat on the water. I was in the patrol boat and met the guys on the water and towed their boat back to the boat ramp to be loaded back onto the trailer. I towed the boat in and we got the boat loaded back onto the trailer and out of the lake. Once we got the boat onto the trailer it appeared as though a 1.5 foot by 2.5 foot section of the fiberglass hull had broken free from the underside of the boat causing the boat to take on water. I have no other information at this time.
  
  Officer stated that looking at the boat this vessel had experienced a catastrophic hull failure resulting in the hull being breached, like the hull had been patched from an earlier damage, and the pressure on the hull may have caused the hull to fracture and the vessel taking on water. The exact reason for the hull to fail is unknown at this time.
