FYI - Anyone fishing Smith out of the Dam - take care if you use the "new" dock with single ramp (running parallel to the Dam) - there are quite a few screws that were used to attach the rubber bump rail to the dock - sticking out, bent over, etc. - in a perfect position to seriously scratch your hull. It looks like when the person put on the rubber rail used standard deck type screws (star drive) the heads were too small and just pulled through the rubber lip - so they drove some in halfway and then just bent them over - making the perfect tool to scratch the side of your boat.
The dock at the twin ramps (facing Dam) - did not seem to have this issue at least where I tied up. I was there over the weekend and this was new to me - as I hadn't been there in a while.
Good Luck.
