O1 was in the process of loading his boat after a fishing tournament that was taking place on Lake Francis Case. O1 was near the Cedar Shore Boat ramp, this is in Lyman County, South Dakota. After dropping off his fishing partner on the dock to get the truck and trailer, O1 was backing away from the dock slowly to stay out of the way. While backing up, a different boat was coming from the dock area and was approaching O1. O1 did not see O2. O2 hollered to get O1's attention. While turning to look, O1 accidently pushed the throttle further in reverse. O1 over corrected and pushed the throttle all the way forward. The sudden burst forward knocked O1 to the floor of his vessel, and O1 was unable to get up to reach the throttle. The boat did a few circles, and eventually hit the dock.  O1 was wearing heavy clothes at the time of operation and claims it was hard for him to operate the throttle. O1 also mentioned the wind was pushing his boat around.
