RedactedNarrative: On May 7, 2017 at approximately 18:30 Operator1 was operating a 1999 20'' Sweetwater 20ES pontoon boat, vessel 1, on Douglas Lake in Jefferson County. At the same time Operator2 was operating a 2001 34'' Sea Ray 340 Sundancer, vessel 2, on Douglas Lake in Jefferson County. Vessel 1 was traveling upstream along the right side of the bank towards Swann''s Marina. Vessel 2 was also traveling upstream in the same area. 
  
  A point, approximately .45 miles downstream of the mouth of Seehorn Creek, extends out to restrict upstream visibility of vessels traveling along the right bank. Vessel 1 was traveling beyond the point. Vessel 2 came around the point traveling in a plowing displacement mode, restricting the operator''s visibility. 
  
  Operator2 never saw vessel 1. Upon hearing engine of Vessel 2, Operator1 attempted a starboard side maneuver in order to avoid collision. Vessel 2 made initial contact to vessel 1 on the rear cowling of motor. 
  
  Vessel 2 then proceeded across the stern continuing towards and across port side of vessel 1. Vessel 1 banked right and traveled into the bank while vessel 2 maneuvered port side. Upon collision, Operator1 was ejected from vessel 1 and sustained injuries.  
  
  Operator1 refused medical treatment.  Operator2 stated she circled back to "see what kind of log she ran over." This was the first time she saw vessel 1 and that she had not ran over a log but had collided with another boat.  Operator2 retrieved Operator1 from the water, and provided first aid to some of her injuries.  
  
  Based on officer investigation and statements of parties involved Operator2 was at fault. With her vessel being large and sitting high above the water there is a restriction of visibility. Add that along with a plowing displacement where the front of the boat rides high and a point restricting the view there was a need for more operator attention than what was being used. 
  
  Operator2 demonstrated improper lookout at a time where there were visibility restrictions with her vessel. She did not give way to the stand on vessel that she was overtaking. She also did not take early and substantial action to avoid a collision.
