I betcha you could use my handy dandy home-made carp pod for a rod holder...you only need two bank sticks, a 5 foot piece of 2" x 6", a 1/2 inch drill/spade bit and some screws/nails...
I built it for fishing off cement sidewalls of dams or off docks (Big Cliff is not fond of me drilling holes in his dock for my bank sitcks... )
Here are a couple of pics...one with just bank sticks and the other with my buzzer set-up...
Once you get too frustrated trying to build rods and pack it in...you can take up carp fishing...
