Conventional antifooul vs Coppercoat

[Champagne Murphy]

Pics after using Coppercoat on the keel and Jotun eroding on the hull. She's moored on the Orwell (swinging mooring).
In short, there doesn't seem to be much difference.

I had thought about Coppercoat for next year but the reports here have put me off. Time for a blast though.

? Which reports.

? Which reports.

There have been lots of threads about it and one contained many negative comments particularly on the east coast.

I thought the point about Coppercoat is not that it is "better" in the short-term, but that it lasts 10 years with only minimal maintenance.

I think you have only been reading the negative ones. The positive ones will take longer to read mind you.

Are you suggesting the OP was being negative?

As for the "lots of negative reports " almost all are 3rd party. People who actually have it usually like it. Unless they didn't RTFM.

A third of the coat of coppecoating is the blast. If you are doing a blast this year, coppecoat will cost less than double the conventional. And last 15 times longer.

Applied on (actually, under) a 40 footer in 2006, will probably reapply next spring.
Once-a-year blast while greasing prop and changing anodes.
1 and a half hour deal suspended, while crew gone for lunch.
Forever CC!

in a reasonably controlled experiment it appears Coppercoat is not quite as good as an eroding antifouling in preventing fouling, but most would point out the benefit of not having to replace it annually.
It does have to be applied in a professional manner and under strictly controlled consitions. Generally those conditions appear to have not been applied in the majority of adverse reports.
I had the forerunner of Coppercoat - Scott Bader's Cystic Copperclad. As far as I was concerned the 6 monthly requirement for all-over abrasion was far more onerous than annual applications of antifoul - the cost of 2.5 litres of antifoul (which is all it takes to give my boat 1 coat) is negligible.
In the Med with its (generally) low fouling rates one coat easily does a season of 6 months. However during that period the boat will do 1350 - 2800 nautical miles which means it's not still for too long growing herbiage.

We have two year old CC on our yacht. We are doing an Atlantic circuit at the moment andwe like the fact that the CC can be scrubbed with my diving gear to remove slim. We haven't had a single barnacle on it but the prop is a different story. the polished prop attracts the criters like you wouldnt believe. We expect to have to clean the bottom every 2 to 3 months to keep it slime free in the high fouling areas we have been cruising in. looking at some of the visiting boats in the marina here in Lanzarote with the most amazing criter growth on their antifouling I don't think we do bad.

It does not have to be applied professionally. The only criteria for successful application is as you allude to above is that it has to be applied strictly to the instructions.

No I don't. (and it was professionally applied) It's been cr*p and I'm going to be plastering loads of Micron Extra antifouling over the top of my CC next season.

My boat needed two scrubs, each removing weed up to 5 inches long, with a couple more inches of weed growing before lift-out. A neighbouring boat with Micron Extra had a little green slime when lifted out.
