RedactedNarrative: V1 was checking bank poles on the Skunk River when the vessel became high centered on a submerged log. After trying to get the vessel off the log, he noticed water began pouring over the stern of the vessel onto the floor board. The Operator decided they needed to abort the vessel & he & his passenger both ejected over the starboard side of the vessel.  As they did that, the weight distribution allowed the vessel to completely flip over & become capsized into the river.  The vessel floated a few feet down river where it then became stuck on the bottom of the river.
