Just to clarify my origianl post:

Cost is not a concern here with respect to running large wires from the
house battery to the windlass location.

However the path for running large wires is horrible. I am not even sure
I can get 4 or 6 AWG wires through the limited space.

That is why I am strongly considering a windlass battery up forward in
the anchor locker.

I would MUCH prefer not having the maintenance issues associated with
yet another battery but I really don't have a lot of options.

Thanks
