Question COPPERCOAT Is it worth it?

Have you applied this product to your boat? If so, was it worth it? Too early to decide?

I've seen about three YouTube videos on the topic. If I recall, one video showed they didn't apply properly, the other two seemed to go alright.

The website states about 10 years with minor touch ups depending on the area the boat is kept.

I have been pleased using Pettit SR60 for the past several years but this summer or next I may make a change...

Re: COPPERCOAT Is it worth it?

After talking to everybody I meet who has it and reading a multitude of posts, it doesn't seem to be worth it for us, down here in the tropics. It is definitely not an answer to antifouling, though it seems to be a good hard solid paint.
I have found that none of the antifouling paints, cheap or expensive, last more than 3 to 5 months before it's time to jump in the water and start cleaning the bottom. The last paint we tried was us$7.50 a gallon and it worked as well as any us$350.00 a gallon paint we have ever tried. This time we tried an antifouling paint (us$100.00 gallon) specially formulated for slow moving harbor work boats and it has only been two months so we'll see. However, to be fair, with the quarantine, we aren't moving at all, so this paint won't get enough action to slough properly.

As an update, we are still having it cleaned every month, while other boats around us are going every other month, and the diver still says "whew" and sits on the dock quietly for 10min when he is done. Within a day after being cleaned, it is growing visible slime and grass again.

As before, the good things about it is that I can tell the diver to take his metal blade and go at it at will. Also, when it is clean, it is a hard, smooth, fast bottom - much more so than bottom paint.

But you have to get it clean first, and that better be within a short time before you plan to sail it.

Re: COPPERCOAT Is it worth it?

I think anti fouling paints simply can't do the job they claim. Either they are not poisonous enough for whatever reason... or growth is not bothered and will still attach to it.

It's expensive to apply... very. And what is more effective is frequent diver cleaning. Frequent is determined by where you boat ie how alive the water is with critters etc... how much you sail the boat etc. More frequent is less work for the diver to clean it.

Consider not painting every year and use the savings for divers over the two years.

pay attention... someone's life depends on it

Quite the contrary....the Petit Ultima 60 I uselasts 3 years and does a very good job in a high growth area
You live in an area with a short sailing season so maybe it’s cost effective, but using Ultima 60 costs are much cheaper by far.

I fully agree with SanderO. No bottom paint we have tried over the years did what it was supposed to do. There was no other choice for us to try but Coppercoat. Since we were doing the work ourselves, we did not have to pay the incredible amounts of money other people have paid. At the same time, I did our second application of Propspeed. Two weeks ago, I did a four month check on our Coppercoat. What was good about this, is that another boat was launched at the same time as us but used expensive, traditional, antifouling applied by a yard contractor. Our 2 boats sat in a nutrient rich, warm, nasty ass, estuary for 2 months then moved to a marina over 800 miles away, where the water is far colder. At this new marina, both boats sat just a few slips away from each other for another 2 months. That is when I went into the water to video the two boats. For the most part, the other boat has tenacious green grass growing in most places, including at the waterline. He had to hire a pro diver to spend a lot of time scraping and scrubbing the bottom. Inexplicably, there was no growth in some places. I was a bit concerned when I went into the water and saw a layer of stuff adhered to our bottom. But....when I wiped it, it came off like dust. There was no real adhesion anywhere. Just a soft sponge, like what you would use to polish a car, was all that was needed to dust the slime layer off of our hull. At no time was there any weed growth at the waterline nor any barnacles, anywhere. Just that alone, made me very appreciative of Coppercoat. So far so good. On our friends boat, they applied NO antifouling to the prop or shaft. What a disaster that was. If they got any propulsion out of that prop, it wasn't much. The growth on our Propspeed, on the prop and shaft, maybe had a bit less growth than what was on the Coppercoat, but it also brushed off easily with the sponge. This coming Thursday, 16 Apr.,or Friday, we will put up a video covering this comparison with underwater clips.
