Sounds like you're working it out. :goodjob
The bungee cords I used were the kind you cut to any length needed and the plastic hooks crimp on to the ends. The ends stayed on the base unit hanging there when not in use so as not to get lost.
On my Marlin, I replaced the pieces of Starboard in the mid-berth with longer ones to hang 6 rods instead of 4 and in the starboard V (the short side because of the TV) I installed reel hangers to hold two 53" rods, my kite rod and a rod I cut down and is dedicated to use as a release rod with the Seaqualizer I just bought.
Gotta be inventive sometimes to find new ways for storage!
Always :hmm
