Re: [Amel Yacht Owners] Grounding

Thanks for this Tom. I'm still a little concerned as the copper
terminal has two DC ground straps bolted to it. Otherwise the copper terminal has indeed the appearance of being an RF ground, being, as I recall, a three inch copper strip which just appears out of the gelcoat. Did you disconnect similar DC straps when you attached your RF ground? I'm happy to do that in general as advice has changed over the life of our boats such that you are now told to disconnect metallic thru-hulls from each other and from the DC ground because of the risk of galvanic corrosion occurring in marinas, where control of stray electric currents tends to be poor and has much worsened over the years. I have found a photo of my boat out of the water some time ago and there is clearly a plate on the starboard side of the skeg, although not on the port side whereas you mentioned plates in the plural. Do you think you have one or two? I tend to agree that there's no sign of a lightning ground, so I'm getting ready to install one at the next haul in September.
