Further to this topic.

Our grounding wire is a braided copper strip approx. 3/8 inch wide and flat.  A 
section has corroded and is no longer attached and that section needs to be 
replaced.  Is this the same thing we are already discussing?  Han I purchase o 
new section of this wire in the suitable length and splice it somehow?

Take a look at the link.  Specifically page 35 talks about DC grounds, galvanic 
protection, and lightning grounds.

For a lightning ground which is coupling the mast to the keel I would consider 
using copper bar stock.  Keep it as straight as possible and if a bend is 
required, make it gradual.  Bar stock of sufficient width so that a hole can be 
drilled in it large enough to fit a keel bolt.

For a DC ground I would consider drilling a hole in the side of a nut which 
fits the keel bolt.  Tap the hole in the nut and then use that to accommodate 
your ring terminal.  Alternatively, you could drill and tap the keel bolt 
axially and then mount your ring terminal right to the top of the keep bolt.  
The later option will probably be your cheapest and should keep the terminal 
high enough out of incidental bilge water.

Hi Eric!

If you have exposed threads above the existing nuts,  can you just add a lock 
nut on top to secure the wire between the two nuts?

I noticed that the grounding wires in the bilge have been cut (since I 
inherited Cat’s Paw in 2005!) so they are not connected to the keel bolts.  I 
can splice wires onto the cut ends to reach the bolts, but what is recommended 
as terminals to connect the wires to the bolts?  It would be helpful if this 
did not involve unscrewing the big nuts on the bolts, but perhaps some 
terminals that connect to the top of the bolts?
