i like the foam on the siderails of the canoe idea. for the quick lure access i have a method i prefer much better. i dont like having hooks dangling free when i dont have to because its the things you dont expect that always hurt the most. i made a little board that my rod holder is bolted onto. that board is secured to the crossbars of my canoe with 2" wide industrial velcro. that stuff is amazingly strong. i have my pliers, tape measure, and a small plano box 4"x8" (dunno the exact size, the smallest one they sell thats large enough to hold large cranks) that i have velcro on as well. the little plano box velcros to the underside of the rod holder assembly so it is secure and out of the way. any lures you intend on using go in the box. i keep all my trolling cranks in one of the small velcro equipped boxes for the trip in and out.

my main tackle tray is a plano 4700 double layer which is packed to the brim. i leave that in my pack during the portages because its too bulky and heavy to move in and out of the pack. i drilled a couple holes in the little support braces and have it on some paracord with some quick snaps. when i go out fishing for the sake of fishing, i loop the paracord around the crossbars so the tackle box hangs straight down. when i need it, i pick it up on my knees and take what is needed. by hanging, it doesnt make any noise and doesnt clutter the bottom of the canoe. my legs are short, so it doesnt get in the way.  just be sure that you snap both lids... its no fun picking up all the stuff...
