Wire securing

[Locke N Load]

Hey all,

Another topic on my mind while it is still winter and I have not got back to my project is wiring, specifically where to run them.

I can see how movement is bad and wires need to be secured. Easy enough when you are going from a battery switch to a panel or some other relatively short distance, but what about the battery cables from the motor to the batteries when they are stored approximately 12 feet away? My house and starting batteries will be stored under the floor in the cabin. I have a nice secure pad for them. I had planned to run the cables through the vinyl gutter downspouts I used to increase the stringer heights. Now I am not so sure since how will I be able to secure the cables inside the tubes? I figure it will be about 8 feet of inaccessible space.

Will securing the cables at each end be enough to keep them from moving while trailering and on the water? I can see how over such a distance they will be bouncing around some and creating a fatigue point at each securing point.

The other option I am thinking is run them along under the gunnels where there is easy access to secure them every foot or so. The overall length of the cables will have to be more since instead of a nearly straight shot there will be horizontal and vertical stretches as well, but upping a gauge is not a concern.

It is not just the battery cables, but also the engine rigging, steering cables, transducer wire, trim tab wires, stern light and maybe more I am not thinking of right now that will need to run to the stern. I had planned to use both starboard stringer height increasing tubes figuring the 2"x3" space from both would be adequate. They go right to the helm. Will under the starboard gunnel provide enough room for everything? I suppose getting in there and seeing is the only real way to tell. It would still be slick and completely out of view since there is the nice stretch of gunnel drop from the helm to the stern and then the rear seating I made creates a big open space for making turns to the transom and motor well.

Thanks
