RedactedNarrative: On 9-1-2018; I was dispatched to Muskingum River Parkway Lock #10 for a boat that struck the lock door. I contacted the operator of vessel #1 who said he tried to move his boat through the open lock door and swung too wide. The operator said he had tried to move his boat back to the middle of the canal and when he speed his motor up the rear right pontoon of his boat contacted the fully open lock door. The boat received damage to the rear portside pontoon. The operator and all his passengers were not injured. The boat had struck an exposed bolt on the lock door causing an approximate two-inch hole in the upper back half portion of the portside side pontoon.
