RedactedNarrative: At approximately 7:00 pm on July 10, 2017 both V1 & V2 were traveling south on the Mississippi River near the Sullivan Slough boat ramp.  Both vessels were traveling at a fairly fast pace & V2 was in front of V1. V2 let completely off the throttle and turned 180 degrees, causing her to stop in the path of V1. V1 attempted to swerve, but collided with V2 which ejected her from the PWC.  v1 motored back around to V2's position & noticed some bleeding around her left eye. V1 transported the victim on his PWC  and took her to the Sullivan Slough boat ramp. A private citizen took them to the hospital.  The victim received 8 stitches. Both individuals were wearing life jackets.
