RedactedNarrative: On June 2, 2018, at approximately 1:18 p.m., agents were notified of a boat accident via St. Bernard Parish Sheriff's Office.  Hopedale Marina agents learned a subject had been struck by a prop and rushed to Hopedale Marina. Agents arrived at the scene(1:46 P.M.) and observed multiple EMS personnel tending to a subject near the bait shop. The subject had multiple tourniquets due to lacerations on each leg as EMS transferred him into an ambulance. Agents were notified the subject, identified as the victim was being airlifted to University Hospital. Agents questioned the operator regarding the incident.  Agents learned the vessel had been returning from a fishing trip traveling north approaching the Back Levee Canal (Spoil Canal) from Pisana Lagoon. The vessel (16ft Skully) struck an oncoming vessel's wake. When the vessel struck the wake, the victim, who had been bow riding at the time of the incident (sitting on the bow seat), was thrown off the starboard side of the vessel and struck by the propeller. The operator was able to turn and maneuver the vessel to retrieve the victim, who had sustained multiple lacerations on each leg (multiple fractures may also be present). The subjects then tied the bow line around each leg as tourniquets and rushed the victim to Hopedale Marina. Agents documented the vessel and will arrive at University Hospital to deliver the appropriate paperwork and conduct more questioning. Agents cited the operator for violating 34:851.13-improperly riding on deck or gunwales.
