Good PS article at your link, Travis. All more complicated than I imagined, but there is always so much more to learn. Needless to say we will be going over our ground
wiring.
The end of the article provides some insight into why everything was originally bonded together on our boat and why that is not now the best choice.
"In the old days, the technique of bonding everything together worked okay. In its defense, the "bond everything together" approach makes your boat less sensitive to electrolytic
corrosion that can result from faulty wiring on your own boat. The problem is, the "bond everything" approach leaves your boat totally defenseless to wiring errors in nearby boats and nearby industry, that cause stray DC currents to run through the
water.
Today the technique of bonding everything together would still
work fine if your boat spent all of its time on the high seas, in
remote anchorages, or in
marinas that were wired perfectly and in which all of the nearby yachts were wired perfectly. Having underwater metal bonded together in crowded marina's today, however, is asking for expensive trouble."
