I am having difficulty finding this cable. Does anyone know where I may source battery cable? I want to run a positive and negative from battery to front of boat the power windlass. Cable calculator tables say for a
12v
700watt
80 amp max
over 8.5meter distance
I would need about 49mm2 cable which seems about 8mm Dia. Does this cable require to be tinned?

You don't need that for your windlass - 35mm2 will be fine, and give less than 1v drop. Get multistrand cable, it's more flexible and easier to install. Don't be tempted to install an extra battery in the bows, to do it properly is more expensive and far more difficult than just running cables.

I have just replaced all my battery cables with 35mm2 tinned flexible cable. The cheapest place I found for it tinned is Kojaycat

Untinned it was cheaper at battery megastore.

Stuff I used was surprisingly flexible and crimped well. I used an ebay hydraulic crimp tool purchased for about £30 to get good crimp connections and used adhesive heat shrink to seal and reinforce the crimps.

I agree that 35mm2 should be fine.
 
Call your local scrap yard, they often get off cuts of tinned flexible welding cable off cut from damaged sections, much of this is all but brand new and very cheap.

Good luck and fair winds. :)
 
site a battery up forrard to shorten the heavy cable length

...then run cable to it to cope with a charging current of perhaps 70A from your alternator.
Oh, and you'll need to construct a battery box, buy a new battery, switches, maybe diodes. That'll save you lots of time and money and use up locker space you've no need of at all...
 
Thanks for all the replies,I did consider putting a battery up front I do have the space just in the v-berth but how often will this get used other than when the windlass is switched on. Running direccly from the main batteries is what I will be doing probably increase the Ah of he battery to support the windlass.
 
Furneaux Riddall in Portsmouth were very competitive when I upgraded my battery cables recently, they also are happy to fit terminals for you. You need to check the sizes of the terminals at both ends, I foolishly thought they would be the same size but this was not the case!

An adverc 12/12 charger gets over the charging and having to use heavy cable. Nice bit of kit for me so far as in fit and forget. The other option for my bow thruster (heavier current than a windlass) was another 14m of 90mm? CSA cable and how to route it.
