I need to replace my mast grounding wire with 4 AWG (according to my surveyor). It appears to connect at one end to the aluminum base plate of the mast and that nut is accessible and a new cable can be attached with a lug. I have not yet found the other end. Could it be under the keel bolt? I have been thinking of ways to attach to a keel bolt. The easiest would be if I could put a large enough lug on the end to go over a keel bolt and then put another nut on top. I have not found a lug that large so this may be moot. Can you buy a keel bolt nut? Anyone know the spec or a source? Could I trap a large lug between the existing keel nut and a second one? An earlier thread discussed using braided copper instead but that appear to contradict ABYC standards. Any suggestions on the best/easiest way to do this? Thanks- Dave
