RedactedNarrative: Vessel 1 came to a stop and floated too far past a mooring buoy.  
  
  Operator 1 of vessel 1 began communicating with a person ashore who told Operator 1 that the boat needed to reverse in order to position better for mooring; the operated replied 'ok' in response to the person ashore and Victim 1 took that as the sign to exit the vessel and did so Operator 1 reversed, resulting in the victim's foot being taken into the propeller.
