Take a look at G3 boats. Great value and Yamaha powered. It appears TAILWATER MARINE & TACKLE is a dealer in Clarksvilleand Anderson Marine is a dealer in Madison off Old Hickory. Look at the Eagle Series -

I bought my first boat from Anderson, a Skeeter aluminum which was actually made by G3. It had a 90 Yamaha which was bullet proof. A fantastic stable fishing platform that I used primarily in Old Hickory and on the Cumberland.
