RedactedNarrative: Operator was trolling for walleye within the Pier Arms that protect the entrance to Muskegon Lake.  While headed in a westerly direction, he hooked a fish and began to navigate out into Lake Michigan in N/W direction to get away from other vessels in the vicinity.  
  
  It was getting dark when he landed his fish, he noticed that his second lines in the water had become tangled. He realized that he must have been going in a large circle causing his fishing line to become entangled. His was cruising about 25 MPH and about 20 seconds later he crashed into the rocks making up the North Pier.  A citation was issued for fishing without a license.
