If you do stack some rod holders vertically on that arch, they will be the handiest rod holders on the boat. Nothing better than a Tree, or rod holders on the arch, for running boards. When you are reeling in a fish the rods in the arch are forward and totally out of the way. I didn't think I needed a tree, until I built mine last year. I usually run 4 boards off each side, and they are the Cat's A$$.
