The total run from the battery to the windlass and return is 72 feet.



Precisely why the wire is #4 for the long run. #10 is fine for very short
distances, like inside the windlass.

Shhh....don't tell anyone I told you this....#4 wire from the car stereo
shop, or even #2, is LOTS cheaper and works just great!

400% profit doesn't make it work better....(c;

Also try welding cables, which come in these smaller sizes #2 and #4.

Tell your yachtie friends you only used the most expensive "marine grade"
wire from the finest chandlers on the planet....so they don't snub you on
the dock.
