I’m going to be honest. Had a set of these on the rail mounted on my 1648 g3 jon boat and had a heck of a time of trying to fit 6 to 8 rods and reels, be the rods loaded with,spinning reels or my okuma DX 15 and 20s as ther just isn’t the room. Then the weight of the rods would cause a lot of bouncing going down,the highway. So I went with a 3 rod holders of creekslick down the side of my 16’ jon boat, I can remove the very back one if I am using just 5 or 6 ft rods to 8 ft and for my 10-12’ rods back to 3 uprights and the rods travel so much more stable and I am not beating the reels up either. Just my 2 cents as they probably work better on fiberglass boats. Here is a link of creekslicks with pics.
