UK website but none found.

Any pointers

thanks

Steel Canal boats should be wired with all switching in the positive
line, an insulated negative return,but with battery negative bonded to
the hull at one point..

This sounds like normal land electrics.

Blocking diodes for split charging are best avoided.
Bear in mind that all wiring will be 12 or 24 volts and conductor
cross sectional area is important and should be fully assessed based
upon the length of the run.
Methinks that you have not searched very much! There is a wealth of
info out there on the web..

I had a quick surfer a while ago but some info conflicted with
other sites and what seemed to make sense.
My fisrst confusion was the idea of positve earth and what happens when
you tie up at one of those sockets along the canal.

uk.rec.waterways is the best group for asking questions.
Cheers for that.

12v (typ) electrics on a boat are VERY easy to get wrong!!!!!!
Yes that's why I've done nothing, hands in pockets and all that.
12V, lots of amps, water, diesel.... oil.......

Your friends best bet is to get a good marine electrician to spec the
system, then you could wire if you wish.
Just my 2 pennorth

Well the boat ( I wish I understood more of) is around 53ft wooden
boat made in the 1960s (not a narrow boat) and is still floating just.

We got side tracked reading about the creatures that can eat away
at the hull and getting the polarity wrong could mean losing the
screws/nails
holding the thing together and how things differ depending whether you're
in sea water or on the canel, fascinating stuff , I'd no idea of such
things,
bit different to what I'm used to such as wiring computers together.


In the next few weeks it might be ready to be re-wired and/or checked
before plugging anything in that's my plan but wasn't sure what I may face.
I was hoping of a hayes type manual that they have for cars.

I'm also hoping there's a free wi-fi hot spot somewhere along the regents
canel unlikely I guess.

Thanks for replying
