We have a setup similar to yours. However, we also have a combiner for the
start and windlass batteries (both on the same unit), allowing us to charge
either just the house, or both, as situations warrant.
We're very careful about running the house battery alone for loads. In
addition, both of the start and windlass batteries have circuit breakers on
them, so we can separate them if needed..
The cables to the windlass battery are still somewhat considerable, but the
cables to the windlass are impressive. If we were to rely on some battery
to heft it remotely, the cables would have been huge. I'd also hate to have
a house battery drawn down by the level of amps used in the windlass, but
that's probably because I've had to start the engine and get the anchor up
in cases of lower-than-I'd-like house battery state, and that's the way the
boat was configured when we bought it.

I expect to pass this way but once; any good therefore that I can do, or any
kindness that I can show to any fellow creature, let me do it now.
Let me not defer or neglect it, for I shall not pass this way again.
