Willy's got an awesome spread through the water column^^. Knowing that I can't fish comfortably on my 18 with more than one licensed guest on board, I opted to mount my riggers on 36" Cannon tracks on 6" pedestals so I can slide them out of the way when docking/under way. I then mounted a pair of Cannon dual axis rod holders that can go either in front of or behind the riggers on the track for diver rods. We can only fish two rods per license here, so I'm maxed out with this simple rig. If I need another couple of lines I can stack the riggers, I guess. There are all kind of accessories for the tracks, too. Ball holders, cup holders, cleats, step pads. They're pricey but I'm happy with them.
