RedactedNarrative: Operator and his son were traveling downstream on the Caney Fork River. They were in a 15'' Tracker with a 9.9 Mercury. They came under the second I-40 Overpass just past the Smith County Rest Area. When they came to the third I-40 Overpass, the vessel struck the right side pier, due to the strong river current, and started to take on water and then eventually capsized. Operator and his son were able to swim to the bank and reach safety.
