RedactedNarrative: Owner/operator advised he and his occupant were out for a pleasure ride on the Scioto river on his air boat after repairing it over the off season. Owner/operator advised me he was coming off plane when he saw a stump he wanted to mark. As he slowed down he turned sharply left the wake behind him swamped the starboard bow causing the boat to capsize. Subject was wearing his life jacked but failed to properly snap the buckles causing it to come off while he was in the water. Subject began struggling and Occupant drug him to the shoreline. Subject was then transported to Adena Pike Hospital where he was given a breathing treatment and released the same day. At time of writing this report the vessel had been retrieved and is docked on the SRI04 side of the Scioto river. I was not able to respond to the scene so photos were not taken and the image is from google earth in the closest known location of the crash.
