Re: Should I only use the house bank at dock?

Not an issue while in your slip, but you have to remember to switch to the house bank when you leave the slip and go sailing. I would install an automatic charging relay (ACR) that automatically charges both batteries when power is available and disconnects the start battery when sailing. I installed a Blue Sea ACR a couple of years ago as part of an electrical system upgrade and really happy with it. No more constant playing with the battery switch.
