- We've prepped the boat and In this video, we go through all the steps of applying an epoxy barrier coat to the hull, to prevent osmosis. And how we applied the epoxy-based Coppercoat anti-fouling.
We'll also run through the reason why we decided to go to all the trouble of doing so.

That was absolutely first class.
It does seem to be the case that copper coat failures are not product failures but application failures.
Your preparation was meticulous and following the application regime on a hull that size with just the two of you is impressive.
Well done.😀👍⛵️
😅e
You showed the how to do...and that you must have patience to do the job correctly. Nice work!...John
Perfection, love your quality and perfectionism, rare these days but the right way…….we are ocd also but that’s the right thing……love you guys.
Nice! Logical, reasonable and well-thought out. 😀👍👏👏👏
I love the boatyard fox 🦊
Great video and very informative. I’ve got Copper coat on my Rival and I’d do it again. Andy UK
The great thing is you'll likely never need to !
"real grafters" well done!!!!
You do a really good job. 👏 Peel-ply can save sanding between coats if you need to leave the work for a while. Also vinegar kills the epoxy set when you need to clean up.
That is some mighty impressive work going on there. Well done.
Always wanted to give coopercoating my own hull ago but been put off by the horror stories. Thank you for breaking the process down and explaining what not to do, very interesting 🧐
@darrenpye-rs4yf We did coppercoat last year and never looked back. Have the standard anti fouling on the stabilizers and coppercoat on the hull. Difference is immense. Coppercoat is clean, the stabilizers have barnicles starting to grow. In other words, we will never go back to any other anti fouling. Can highly recommend copper coat.
Nice work well done ! Thanks for the explanations.
We have experience at this, very well done.
Copper coat is not easy applied. It needs perfect finishing. If not the coat will fail your boat.
Like this boat it must be perfect. This video is a very good instruction video.
Well done 👍🏻
@MonkPetite that is what I thought as well, but it is not that critical. We have copper coat on our hull and the hull is full with dimples and small damages. Still the copper coat works perfect, no growth at all after 1 year in the water.
Wow the hull looked amazing, a piece of art. Shame it spends most of the time underwater and is never seen.
Great work
Great job 👏🏻👏🏻👏🏻👍
Good discission, we did copper with epoxy, 11 years ago in The Netttherlands and sailed into an area were hauling out is difficult.(asia) Whilst we do need to scrape the hull regularly when longer term in marina (built on a reef iin tropical waters) the Copper coat has helped since applied, not saying zero maintenance, but far less, and we saved a ton because otherwise you need to go out every year. Hauling out in this part of the world may costs 3x the price in Europe, hence there is a savings. We did hera that Australia is not okay with copercoat, but I have no plans going there.
We have a copper coat rep in Australia. He sells plenty
The only thing that really upset me was right at the end of the video ......the feet. I thought I'd blocked it out of my mind forever, but it's right back in there 😂😂😂
I wish i had applied coppercoat 12 years ago when I first bought my boat. It has been more expensive by far to haulout and apply bottom paint five times over that span
.
Have you also found hard growth on your ablative antifouling? Because I have
Last picture ist the best
If you paint again look for the 3 foot roller handle. It makes putting paint on with a roller much easier.
Todo bien. Pero antifouling le pongo una capa Hempel auto pulimentable y en algunas zonas de timón y orza, matriz dura y luego autopulimentable, y así cada año.
👍
Coppercoat is great, when you can get it.
Merci!
WoW thanks, we will put this towards upgrading our camera equipment. Glad your enjoying our videos
Great Job, nicely done. No criticism, however you do not want Square trailing edges, particularly on Rudders, rather 45° for better shedding of tip vortices, look it up. Maybe next time😉. My other comments, from hard earned experience, is to check the other elements of the steering system, particularly cheek Block attachment, sheaves and axles etc, as their bonding and integrity become more stressed now that rudder is more efficient and the shaft more rigidly located in new bearing collars, within the hull. Think of it as a whole, and where is the weakest link? Same applies to sheets and halyards that get replaced with high performance low stretch ropes & lines as their lack of give transfers much higher shock loads and strain into blocks and clutches everywhere else........ But excellent to see such careful refurbishment of your pride & joy. Can't help but feel that Copper coat, whilst the right choice, needs owner application (with skill & care) that some if not most boat yards would not take. Fair Winds & Smooth Seas.
Yep, not knowing much about boat designs, I was a bit surprised to hear about square edge for the rudder as way to fight turbulence. Sounded very counter-intuitive
I have worked mostly rebuilding old schooners and we put blunt trailing edges on the rudders because that was traditional, the theory being that the turbulence caused by the edge produced less drag . Like driving a pickup with the tailgate down causes more drag and uses more fuel. High speed rudders of course have a very fine edge.
Je dois faire aussi ma quille. Vous mettez de la résine epoxy directement sur la quille, c’est bien cela ?
Yes, epoxy directly on the keel.
If you have a solid lead or steel keel, the West system G-flex will bond better to the bare metal.
@@SailingHiraeth ok thank you so much.
Hi great work! How do you best deal with the stand pads areas?
Lol just watched the rest of the video! Lol Sorry !
You might have to rake your mast a little if you generate lift with the rudder. NACA 0006 hydrofoil
What’s the make/model of this boat?
Centurion 42 built by the French boatyard Wauquiez in 1987
@@SailingHiraeth thanks, nice work
Nice work! However, if the copper is exposed by the Scotch Brite, it has to leach into the water. Otherwise it would have no antifouling effect.
Should be dusted on tacky coat then dry rolled so it remains exposed. Copper is illegal in many harbors, they come around and check to see if it is going green at the waterline.
@@D-B-CooperI don't see why, given that most antifouling is copper based anyway along with being ablative and toxic as hell.
Can this be sprayed on, this would keep the mix more constant.
Yes, it can. Coppercoat have application directions for this.
I don't think I would try it outside though.
Your coppercoat final appearance looks quite a bit different than the result Mads achieved on his boat Athena at Sail Life. Or am I imagining things?
We are finishing applying our copper coat. We are now exposing the copper with 320grit sand paper. The instructions we got from copper coat says to sand alot more that what it looks like you did with the scotch brite pad.
How has it been holding up for you you?
We've had the Coppercoat on for 3 years now, and it's been great. This is the first year we've had to do anything other than power wash it.
We had a small amount of growth accumulate around the water line over the winter, so we've just given it all a once over with scotchbrite pads.
We might put a quick update video out to show what we did.
Does a copper coat really last 10 years, even in warm waters? Nice job BTW!
Coppercoat say it should last at least 10:years.
You occasionally need to re-abrade the surface to refresh the copper oxide. When you eventually need to reapply, it only needs 2 coats over the top.
@mikefriend7570 I'm in Florida and prepping my sailboat for Coppercoat. Here in the Gulf of Mexico and Keys, cruisers have seen longer than 12 years. I don't know how long it lasts as the 12 year old applications are still going. They still come out every year or two to check running gear, and touch up the bottom of the keel if they get into sand during the year. If applied correctly it "just works".

Had cc long time ago. I am in very warm mediterranean waters (croatia, italy) . Was ok for the first 2 years but then too much growth on it and cleaning was too time consuming. Went back to normal antifouling, it is cheaper and taking out the boat is good anyway. Would not use it again.
Aluminum powder in the epoxy makes it very hard and scratch resistant
Hempel silic 1 is a better solution
My friend used copper coat on his 45' cat. It got hit by lightning three times during two years destroying his electronics. This happened when at anchorage with many other sailboats none of which got hit at all. Hmmm.
That's probably one very good reason not to go that route then?
Maybe durning lighting storms disconnect electrical
My friend used copper coat and fell off a ladder.
Ware - not every coppercoat application, even tho surface prepared and product applied as per instructions, has lasted as well as advertised.
I watched entire video for ONE reason - to find out the details of your HEADLINE "Why we said Goodbye to Anti-fouling Paint."
After watching a well-done video, unfortunately you said almost NOTHING about why Coppercoat has superior attributes.
dreaming,,,,
back to antifouling, soon,,,,
I run a marina in Massachusetts and if I saw you working like that without drop clothes underneath the boat to protect the soil, I’d throw you off the property.
While you are right, there's got to be a better way to encourage people to take care. Something like "the ocean is obviously important to you, since you're investing all your energy into fixing your boat. All the sanding residue washes into the water unless you take a few easy steps, like tarping under the boat to collect debris and using hepa grade dust collection when sanding."
All yards have rules, most now have runoff water testing and this wouldn’t be allowed. I had a laugh at the rudder hole.
Take it easy tough guy
Looks like it keeps the weeds away.....
I would never enter a marina that has a manager like you who is rude instead of polite, prefers to be destructive/hurtful instead of being constructive, or has a habit of doing so.
2:03 i think that is called a slick. Sometimes they are made with thin flexible steel.
