I had a homemade multiple rack that went around the seat post and held 4 rods if I remember right, that I made out of PVC years ago. It got stolen at a boat launch and I never made another. It was made, if I remember right with a 1 1/2″ tee glued vertically with a piece of pipe about 18″-24″ long that ended at another tee that was horizontal and had multiple 1 1/4″ tees on each side of the center tee with short pieces of pipe cut for rod handles in each of the outside tees, and a street ell and end cap on each end for feet. I had made it out of scrap pipe and parts I had around the house at the time.
