RedactedNarrative: Unit 1 was drifting down in the Savannah River.  The vessel was idling with several passengers onboard while several other passengers were swimming and drifting with the vessel.  At some point, the operator put the vessel in reverse in an attempt to avoid drifting into the bank.  The victim was struck by the propeller while swimming near the back of the vessel.  The passengers of the boat were able to get the victim into the boat and back to a landing.  The victim was airlifted to the hospital where his leg was later amputated.
