RedactedNarrative: On September 9, 2017 vessel one was traveling north on the Red River when vessel one struck a submerged object around GPS coordinates (32 08.199'N 93 27.144'W).  The operator stated he was traveling approximately 40 mph when he struck the object.  The operator of vessel one was also wearing a PFD, and had the kill switch lanyard attached.  Vessel one had two type III PFD's and one type IV PFD on board.  Vessel one is a console steering power boat with a 225 Yamaha outboard.  Vessel one operator stated that he was unfamiliar and inexperienced with the river, and was in fifteen feet of water when the accident happened.  Operator one was looking for ATONS, and the underwater obstruction was not visible.  Transfer marks of red paint were evident on the outboard's lower unit.  The color is consistent in color with the red buoys for ATONS.  Given the photograph of operator of vessel one's chart plotter, the path of travel goes over the approximate location of the navigational nun body.
