Why add the extra weight f a battery in the front where you don't want it?

I'd use heavy gauge wire and run it from the house bank.

I am considering adding a electric windlass to my boat and I would like
some
opinions on the best way to connect to the electrical system.

The windlass will be approximately 40 feet from my house battery bank
which is
700amps. It has been suggested to me to place a small battery up close to
the
windlass so you don't have to run heavy battery cable such a distance and
sustain the power loss. Small cable could be run to the battery strictly
for
recharging.

Thanks for the help.
