My H430 uses the Anchorman 700. Most were installed, as an option, at the Dealerships. So Hunter made the space available for most of their big boat models.
Respectfully, don't do this. Like EVER.
Having a separate battery for windlass (or thruster) is great when everything is going your way. But, now let's consider that it's 2AM, your neighbour's anchor is dragging, and you have to get out of dodge in a hurry.
But, your anchor is snagged on something, so you are raising, lowering, and all sorts of frantic stuff.
And that poor stand alone battery is getting about 20 Amps of charge at best (from the alternator), and when you REALLY need a honking big battery bank to power the windlass , you don't have it.
Many of the French built boats use a separate thruster / windlass battery, and the whole purpose is to save money on battery cable. I find this to be really shoddy practice.
So, use your house bank, spend your kids' inheritance on 2/0 cable, and never risk having your windlass crap out when you really need it
Although my 75 amp circuit uses 2/0 which means 2 gauges UNDER 0 gauge wire. They minimum size is 4 gauge for my run of ≈28', but the power lost and over heating of #4 will probably trip your breaker more.
Never use you Windlass to pull your boat!
This a picture of my Windlass contactor and 2/0 wire.

You might save wiring by putting a separate battery near the windlass. It is wired to my engine starter battery for high amp pulls.
