I've got a 1946 Norwegian built doubleender 36'
She's silicon bronze fastened, Iron keel, monel keelbolts, bronze Pintles and gudgeons.
Couple a years ago, we got rid of our Atomic4 and decided living without an inboard. We love it! She handles beautiful without all that weight.
Anyway, after a 1.5 year haul out, we got a new sternpost(got rid of the prop shaft), 25 new planks, Floor timbers, Keelbolts, etc....
My electrical question : I've got split 12V DC sys. (4x6V) and no A/C at all. Everything is wired from Battery to the load and back to Battery via wires(Simplified description). There is no other elec.ground other than the Neg post on the battery (no plate on the hull, etc...) Batteries are charged by Windgen, Towing gen. and solar panels. Is this an O.K system?
What could be improved?
My Corrosion question: The iron keel is held on by monel keel bolts and protected with RED HAND and Thru-Hulls are Silicon Bronze so are the Gudeons and Pintles. There's no other harware below the water line. There's no Zincs anywhere.
No bonding system either. The metals look good (no evidence of Angel hair) I guess I'm worried that maybe the wood is being eaten away since we found quite a bit of wood burning during our haul out. What can I do to ease my mind ? Any multimeter test i can do to see what's going on?
Thanks for all the info>
