On July 4th, at approximately 1630, unit 1 pulled up to drum island in the Charleston Habor, anchored and turned off the motor. 

At that time a passenger went into the water to go to the bathroom. The anchor of unit 1 did not catch so the operator of unit 1 put the motor back on while the passenger was in the water. 

As the passenger tried to get back to the boat, she was struck by the propeller of unit 1. At that time, she was rushed to Remley's point where EMS transported her to MUSC. She sustained a propeller strikes on her Knee and foot and had to get stiches in both knee and foot.
