I saw a fella at Holiday last year that had mounted some dubro rod hangers to custom bent strips of aluminum that, once attached between the underside of his gunnels and deck, would hold the rods just under the gunnels. He had a 20' boat and was able to have four rods stored this way.
I could see where you could fashion something similar to utilize the t-rack. I am debating doing the same thing with my boat to keep the rods from being in the way.
I wish my Xpress had t-track gunnels, so many gadgets and doohickies I could dream up to mount on them.
If you're not living on the edge, you're taking up too much space!
