Common DIY mistake.
The only practical way to run cables
from the house bank to the windlass (or windlass battery) using lighter gauge wires than will support the max current
of the windlass is to install a current limiting charger
like an echo or duo charger.
It has to be a very big boat
(or windlass), for the advantages of a dedicated battery forward, to be more economical than running proper sized cables
from the house bank.
Come on guy......
Have you even seen a number 4 awg cable?
Have you priced 70 feet of 0 gauge wire? ( btw 0 is bigger than 4 )
You don't think I haven't thought about fire hazard, I believe that was my whole point and one of the reasons I use a heavy duty battery forward.
And fyi it is large enough boat, w 300 feet of pretty heavy chain.
Bow thruster batteries on Beneteau oceanis
Go over to the thread about bow thrusters... They seem to understand basics.
Please don't comment about DIY mistakes
(Common or otherwise) till you actually try this stuff or your have an electrician x - plane it to you.
P.S. If you were any kind of electrician like the one I had approve my installation
then you would have asked for more info before you accused me of making a common DIY mistake.
PS.PS. Have you heard of fuses
? You should check them out. Not using them is a very common DIY mistake.
Seriously you should think about things and ask questions if you don't know the slightest thing about what you talking about. You could mislead folks into thinking you just put 2 giant cables from the front of a 40 + foot boat to drive a piece of equipment
all the way from the back and that is that.
Have you heard of vibration damage?
The bow of the boat takes a bigger pounding than other parts
of a boat ( unless your sailing backwards, which judging by some of the comments I've read on this thread wouldn't surprise me. )..... Putting a nice battery charger in the bow, is truly a failure waiting to happen.
