I Can’t Believe It’s Not Coppercoat!

Try electric motors as tender engines or auxiliaries. Like long lasting AFs dominated by things that do not exist - but might - unlike anchors where too much exists already.

Oddly, I did just that and read through the thread. I agree with what you say. The other thread of the same diversional ilk is the rant on magazine content (currently drifted toward how to service a Triumph Herald.) Many of the threads are simply nostalgia for an expatriate. When I want to weep over my malt I watch one of Dylan's videos.

So, did the experimental copper - epoxy mixture work? And if so, what were the specifications for the copper and epoxy?

Getting specific about the copper content...

Synergy wrote to me answering the question

how many kg per liter

Answer 3 kg per liter of epoxy

Now the Coppercoat foirm claims that 80% is the max allowed by law.

Whose law?????

What is this all about?

3 kg per litre works out at about 75%; assuming the resin has a density around that of water.

...but becomes somewhat higher in the finished coating as the water in the resin evaporates.
I'm afraid I can't help ianabc on the provenance of the regulation, but Ewan of AMC has mentioned it on several occasions. Maybe he'll be along to add more info.

Apologies if this has been mentioned already, I haven't read every post on this thread, but when I bought my new boat, a Jeanneau, I wanted to copper coat it. The dealer persuaded me not to, because he said it might cause problems if I ever had to claim against the hull warranty. I decided the following year that I was going for copper coat regardless. When I went back to the company who gave me a quote the previous year, the price had gone up by £1400, to cover removing the one year of anti foul. The copper coat has been on for six years now, it is a turquoise green above the waterline and darker green below, but the colour is solid over the hull without any. streaks or copper coloured bits. My friend bought a Bavaria a few years ago and decided to copper coat it from new. His boat has been lifted twice since then and on both occasions there were bits of the coating which had to be repaired, because it had blistered. Both boats were copper coated professionally by the same company, they are in the same marina, just a few berths apart. I can't help but wonder if there is something that leaches out of a new hull that compromises the coating.

Having read a number of threads on the subject I understand that coppercoat is applied to a reasonable number of new boats. There might be something leaching out but it might also be resin dependent as if it were a common problems we would have heard of many more complaints. I might throw weather into the mix as an alternative to something leaching. But again - I'd have thought ABC would have any weather/atmosphere influences well documented by now.

What I do note is that there are a few application issues that seem unexplained and there are a few issues with performance, which might relate to application, (not enough to discourage me) but enough to suggest there are still a few question marks - as you indicate
