I'm trying to find a place to store my boat hook and a side or my back rail might work. The problem is I can find many many pole storage clips that screw in, but nowhere can I find a pole storage clip that mounts to a side or back rail!! I find fish pole mounts and flag pole mounts and grill mounts and several other things that mount to a boat rail but no storage clips. This seems like it would be a useful item. Can someone please help?
