RedactedNarrative: Boat B south bound at SNW speed, had just come out of the SNW zone between Stone Lake and Spider Lake.  About the point of impact the driver of boat B became aware of the other boat, A, bearing down on them at a higher rate of speed and accelerated in an attempt to get out of the way.  Boat A impacted boat B, slid up onto the gunwale of boat A, ahead of the left rear passenger, breaking through the fiberglass gunwale and cracking the side of the port hull.  The impact broke the electric trolling motor loose allowing it to impact boat B and cutting the padding on boat B on the rear edge behind the left rear passenger. Boat A was travelling west, directly into the sun.
