RedactedNarrative: On the above date and time, operator was operating a pwc on the waters of elkhart lake in the township of rhine, sheboygan county. He was traveling southbound when he came around the starboard side of a pontoon boat that was anchored. Operator was operating at greater than slow-no-wake speeds within 100 feet of another boat. Operator informed warden that he was operating at approximately 30 mph when he observed two people on separate tube style floatation devices swimming in the water. He released the throttle of the pwc, thereby limiting his ability to steer. Operator subsequently struck a woman that was swimming backwards towards the pontoon boat with the front port side of the pwc.
