I used to do a lot of shore fishing, so I had compacted my collection down to what fits in a backpack.
I have 4 large, one medium, and one small of the Plano boxes in the backback, plus pliers, line, a bag of plastics, and the fishing regulations book in there.
The bag takes up minimal room in the 14 ft boat. I'll generally take the two or three boxes out of the bag that I'm currently using for the type of fishing I'm doing, and I'll throw the rest of the backpack and its contents into the front storage compartment. Then all that's floating around in there are a few Plano boxes, a landing net, and about 8 fishing poles.
