Harold,
Those are 4 rod rod holders. I have three of them up front almost fully loaded.
This longlining thing is still new to me and I am in the experimental/learning stage. I've been doing a lot of reading on it and trying to figure out what works best for me. Have run 4 8' rods, 2 12' rods and 2 14' rods with all lines running the same distance behind the boat. Single and double rigged. Lines do get crossed but not too many tangles with a speck on the line. As you can tell, i'm a spider rigger but this longlining thing has really got me hooked! I was hooked after the first trip.
