I think that's a bit on the light side. Most charts only show wire run
lengths up to 60' and a medium size windlass is going to be a 100 amp
load anyway.

A 10% voltage drop is significant. Might knock other things off line,
especially any digital devices. I'd prefer to size things for a lower
voltage drop anyway, where practical.


The voltage drop will be at the motor, not the house battery end.
