RedactedNarrative: On April 27, 2019, Operator and two passengers (Subject1 and Subject2) took a newly built 17 ft long aluminum mudboat on a pleasure cruise in the area known locally as the "Copasaw Canal." The vessel had a 37HP inboard motor with remote steering. Kill lanyard and PFDs were not in use, although the vessel was equipped with the items. 
  
  At approximately 7:30p.m., while in shallow marsh near Trapper's Canal, Subject1 used a push-pole to help the operator get out of shallow mud. He stood in the rear, behind the in-board engine, and near the propeller shaft. The engine was in reverse. While pushing on the push-pole, Subject1's foot slipped on the wet deck, and then got caught between the spinning prop-shaft and the aluminum deck. The prop-shaft yoke removed portions of the foot and caused Subject1 to bleed severely. EMS, Terrebonne Parish Sheriff's Office, and Louisiana Dept. of Wildlife and Fisheries Enforcement Div. were notified of the incident at 7:56p.m. 
  
             Upon arriving at Bob's Bayou Black Marina, Air Med paramedics loaded Subject1 onto a waiting helicopter and flew him to University Medical Center (New Orleans) for emergency treatment and surgery. Agents gathered information, took photographs, and interviewed Operator and Subject2 in order to complete a boating incident report. During the investigation, SA asked Operator to participate in Standardized Field Sobriety Tests due to the serious nature of injuries incurred. He agreed to participate and performed well on the Horizontal Gaze Nystagmus, Walk and Turn, and One Leg Stand tests. Agents found no evidence of impairment and do not believe it be a contributing factor in the incident.
