Bow thruster bat tie in with house bank

[gpeacock]

Everyone: Thanks for the great responses.
Here is what I've come up with and why. Maybe in a few years I will have real world experience that can confirm (or dispute) my decision.
As much as I'd like to have a device that can "do everything" I think the laws of physics prevents it. A device like the Combiner100 is close, BUT...
It would require me to only use the forward bank capacity for the windlass and thruster. This is a waste of good AH IMHO
It also limits how much charge gets to the forward bank. Not an issue for me given I've sized the wiring and fuses accordingly.

I am going with my original plan with a few additions. Im going to add in a way to isolate the batteries from each other and have purchased a backup charger which can be used to bring the forward bank up to a full charge independently when ever we are at a dock. Time will tell if I get life from both banks I expect.
Thanks
Gary
