Progress so far and a queston

Heres a rough idea of what I mean. I use a battery switch between the two batteries' positives in case I want twice the power, but Im not forced to drain em both while on the water. This way if its nightime or Im running something alot (like lights) that might drain them down I can always cut the dual feed off and NEVER be left without cranking power.
