eureka.
I am going to take some cylindrical containers, PVC pipe or even rubber inner tube and fill 4 ft lengths with steel shot or lead. Then, I will push them up through the access hole forward of the bilge pump on all Epics. It is a 4" or so? hole in the vertical bulkhead leading up into the bow. The steering cables, dash and engine wiring go through this space under the bow floor but it is mostly open. It is kind of where ski lockers are in some boats.
I will try to encase the wiring passing through with extra large split loom, so that there is a chaseway for wiring if I ever need to add more. I will also string a chase through there so I'll be ready to go if I need to pull more wire (always do!)
This should work in any Epic, I think that part of the boat is very similar.
