RedactedNarrative: At approximately 11:00 pm on July 24, 2021, V1 came into the Saylorville Marina and attempted to dock the boat.  A witness who works for the marina saw V1 jolt forward and then heard a "metal on metal" sound occurring at the same time.  V1 then left that slip and motored slowly to another slip.  The witness then followed V1 through the dock walkway system until V1 entered into another slip. The witness stated that the operator of V1 had trouble getting the boat docked and after it was in the slip, the operator fell into the water. The witness helped V1 operator out of the water and had him sit  on the dock. V1 Operator then fell back into the water & was fished out by the witness again. DNR Officers arrived and V1 Operator was processed and arrested for BWI.  Alcohol was involved & the subject was not wearing a life jacket.
