Had a dock like that on lake Guntersville. I was fishing the dock next to it. The owner of the dock covered in cattle panels remarked that people like me was the reason he had to fence his dock in. Out of meanness I shot jigs through the holes in the cattle panels while he was telling me he owned the water around his dock for so many feet. When I was back through that way he had put chicken wire over the cattle panels. Best one i have seen lately is plastic coated wire shelving. Used to under pin a dock
The love for fishing is one of the best gifts you can pass along
