Thanks for the reply Glenn.

The batteries are on the port side down in the engine compartment. To
come from there to where the breaker and control relay is located is
15 feet. From the breaker I have to go back down to the bottom of the
boat and gradually up to the bow where the windlass is located. :-(

I wonder if it is possible to run the chain from the bow through the
cabin and mount the windlass at the battery? Just Kidding! :-)

Wire size is a function of amp load and distance. The #10 leads on the
windlass are only about 2' long so they can carry 50 amps with a voltage
drop of only 2%.

With 50 amps on a 72' run #4 is the absolute minimum size you should use.
Even then including the windlass leads you will be close to 10% voltage
drop. Using #8 you would loose more than 20%.

How are you routing the wire to use up 72' on a 27' boat?
