Racereed,

I like your idea for a center console fishing boat. With a 36" hull, you should have plenty of space to do what you want. On a few center console boats that I have been on, toward the bow is usually a place where there is a small rise with a platform that would have a cushon on it for sitting. that would be a good place to hide the ESC or receiver if you put in a hatch. I would guess to make the console also removable so that you could put one of those items in there as well. For Batteries, maybe make a large removable hatch just forward the console for battery storage. I'm guessing shop around for flat battery packs that would power the 3 motors and use their dimensions to determine floor height. Lipos would probably be a good solution.

On my father's full sized center console fishing boat, he has a door on the right of the console, when you open it, you step down into a head with porter potty & sink. Just forward the console, he has a bench for sitting that doubles as a cooler and forward that toward the bow is the rise with the cushon.

Just as an idea to hide your RC gear.
