If you fish for big cats, I think you might have problems with the mount. The rod holders look tough enough. You have 50+ lb line and the leverage of that tall mount, its asking a lot to hold a big fish. Unless you use bolts, to mount to the deck. I would not trust screws (I recently broke a 1/4" screw on a 5" tall holder with a hang up with 20' line. The line finally snapped, drifting in the wind at .6 knots, but it snapped a screw).
