great product no problems after 4 years, and we dont come out for a spray off - all you doubters eat your hearts out - 10 - 15 years between anti fouls must be good news - best £600 spent on boating ever.

I've used Coppercoat on two boats and have been pleased with the results. It does pretty much what it says on the...er...plastic bottle.
In UK waters it seems to work much as well as a good conventional antifoul. So, as other posts note, it needs pressure-washing at lift-out and perhaps lightly abrading before lift-in. The attraction is more than financial. Who wants to apply antifoul annually if they don't have to?

Another endorsement: 5 coats Copperbot (now called Coppercoat) applied to a very fresh epoxy sheathing in 1966 (actually 1996): effective protection: power-washed on lift-out, light abrasion before lift-in (about 2 hours easy work).
In terms of standard conventional antifouling, recovered its cost in 6 or 7 years: clear profit since: no sign yet of wear-through: hoping for another five years.
And what a relief not having to mess around with scrapers, pots & brushes!

Our experience: 4 coats of 'Copperbot' (now called Coppercoat) on newly finished epoxy have now completed ten seasons. It was one of the best things we have ever done for the boat. Copper has given good service on the hull, needing only a pressure wash on lifting, and a very light hand-rub over with a piece of 600 wet/dry paper before launch (less than an hour for a 10m hull) to remove some weathered oxide and 'reactivate' the coating.

We just bought a boat with Copperbot (now called Coppercoat) - again 10 years old.

The owners said its fine still. They have a small tub of mix which they use to each winter to patch up areas which are very thin. They then just rub the whole hull over with a brillo pad.

We did the same thing (we bought her out of the water) - touched in the parts the surveyor had scraped with some more Coppercoat - and launched her. Seems ok so far.

The one thing I would think about was when to rub the hull over (ours was done in December and not launched until March - I think this is too long and it may loose effectiveness - next year I will give her a good rub down the day she goes in)

I applied Copperbot (now called Coppercoat), of blessed memory, to my keel about 7 years ago. No fouling has ever deposited itself upon the keel since that day.

Have had Coppercoat for a few years now. Good results with some slime but very little else. Have never even abraded, but might this year.

We had ours professionally applied in a controlled environment. Don't know if that has made the difference or not.

Just had the boat hauled for her annual scrub off. The good news - antifouling is not necessary. We had the boat copper coated 2 years ago and this is our second haul out. We've had a couple of sails this year and I believe this is why the results are better than last year. There was no shell fouling at all and very little weed fouling, just slime really. The parts of the boat which were not copper coated, skeg shoe; prop cutter etc, were heavily fouled with both shell and weed.

I'm a very happy bunny, if this lasts as long as it should I'll be in pocket and I won't have had to antifoul.

Usual disclaimers and stuff - I have no interest in this treatment other than as a happy punter.

pessimist

Hauled out at the weekend after fifteen months in the water. This is the first haul out after the application of Coppercoat and I'm impressed. The boat was barely used last year and has (so far) had little use this season. There was no shell fouling, very little slime but some patches of weed fouling. In general I would guess that there was less fouling than in previous years when we had used top of the range conventional anti fouling. As an added bonus the chap who pressure washed her reckoned the fouling was easier to remove than that found on a conventionally antifouled hull - it took him about 30 minutes for a 41 foot hull.

All the usual disclaimers apply - I have no association with the manufacturer or supplier of the product other than as a (so far) satisfied user.

Shanty

Scotland - Black Isle

Shanty is now in her seventh season since being Copper coated. It’s still going strong - just needs a quick blast with the pressure washer at crane out to shift a light coat of slime, and a light rub down in the spring before crane in.

A great system - go for it.

A report in Feb YM by Dick Durham says that the Cuprotect that was applied to 'Powder Monkey', his Contessa 32, has not worked, in fact much slim and weed has also helped barnacles to grow in several areas. This is despite the boat being kept in a fast flowing tidal stream.

Interesting, because I had thought about Cuprotect before using Coppercoat. Whilst in what was recognised as a particularly bad year for fouling, 2 boats including ours that I know of using Coppercoat, only suffered heavy silting plus weed at the water line, this is despite being kept in a marina with brackish water. Not bad seeing that Coppercoat cost me less than a third the price of the Cuprotect.

I have applied Copper Coat on our Etap 35i. A friend and I applied it ourselves over two coats of ME100 epoxy, this we did in March of this year. The friend who helped has now had Coppercoat on two boats. It was his recommendation that initially interested me.

Just before the Scuttlebutt Cherbourg trip I slipped the boat on the scrubbing posts at Itchenor. There were no crustaceans but a little weed on the water line exposed to the sun at the bow. The rest of the underside was covered in a thin green slime, much as I have seen before on conventional AF.

We used a cold water pressure washer, which took the slime of in about 45 mins for the whole boat.

So far I am pleased with Coppercoat.

We applied Coppercoat, a DIY application in March of 2005. Coppercoat was applied over two coats of ME100 epoxy coating. The reason for our choice was:

The cost of lift out/relaunch etc plus normal antifouling IS expensive, not to mention all the hard work of applying the stuff.

We wanted to leave the boat in the water all year round, hence the epoxy barrier.

Why chose Coppercoat? Well, a good friend of mine had Coppercoat applied to his new boat professionally two years ago. He had it applied professionally as the boat had to be launched in Feb and the only way to get the boat undercover was to contract out the job. He used Coppercoat as it had worked very well, DIY applied on his previous boat for many years. A good recommendation.

When we put our boat onto the scrubbing piles in Sept there was a little weed at the water line and some slime. The weed was most evident on the bow facing the sun. The slime was much the same we used to get on our Blakes eroding antifoul. 20 minutes or so with a pressure washer had all the slim off, back to a clean hull.

For me it looks like it works. At least this winter there will be no antifouling routine with the associated cost. The whole job, for blasting, ME100 epoxy and the Coppercoat came out at about £1500 for a 35ft boat, plus two days over a weekend for application. If you are lucky enough to have a yard that will lift your boat cheaply, then Coppercoat may not provide much of a saving, but for me the whole exercise will be covered within three years.

I’ve had copper coat on for 3.5 years now and have to say it works well. A bit of thin-ish weed around the water line but no shellfish! One thing to note is that the more the boat is used the less the fouling. The boat has not been out for a scrub for 18 months. I would use it again - I have no connection with copper coat.

I put Coppercoat on my boat at the beginning of this season and it works very well. Boats close to me in the marina foul up much quicker. I have not had any growth stuck to the Coppercoat this season, just a slight slime. I'd recommend it. I had originally used standard antifoul on the boat from new for 4 years. It doesn't compare to Coppercoat.

Ahem.... I must trumpet how good my Coppercoat has worked. A friend who's boat is just a few meters away from me in the marina has a LOT of growth, I on the other hand have just a bit of algae. Money well spent me thinks.

Arabian Gulf

Have used Coppercoat for 11 years now, was originally called Copperbot, after 8 years I applied an extra coat. Great stuff, as the previous post mentioned just a jet-wash and light sand and your back in business. Incidentally my boat is in year round.

Arabian Gulf

The warm to very warm waters in the Gulf makes hull growth a big issue, but at least it’s not too cold to swim in and scrape off.
The yacht I now own had Copperbot (now called Coppercoat) applied 12 years or so ago, 3 years ago I sanded the surface down and added 3 more thin coats of Coppercoat.
This summer the water in the Marina was at about 36 deg c, during this time (3 months) I never dived on the hull, the powerboat moored next to me was barnacle encrusted and growing a long beard, even with constant use.
Yesterday I polished off a thin brown coating of slime and a handful of barnacles under the keel and around the waterline.
Coppercoat is so far the best antifoul product I’ve come across, but it must be reactivated every 2 or 3 years by lifting out and sanding back with 400 grit paper.

Hi John
Still pleased with it 2 years on, boat is in the water mostly all year round so same again just a blast off with a pressure washer although I used the Sealift in Cowes and it came up great !
Probably have a go with some wet and dry paper to re-activate it again in a couple of years, but def worth it! No nasty scraping and painting each year.

We've Coppercoat on our 46 footer - and ours is parked in Mallorca after 6 months cruising the med (with exceptionally warm waters this year) - and bottoms clean as.

I had Coppercoat applied a year ago and despite travels in warmer climates it has worked well for me - so far.
On my last dive under it only took a light wipe to remove slime.

Aqua Sulis

I helped friends apply Copperbot (now called Coppercoat) to their 45' hull three years ago, and they've been doing 'The Atlantic Circuit' ever since. They've had to wipe off slime here and there, and took opportunity of helpers to 'burnish' a bit. No problems reported at all.

Coppercoat is a two pack epoxy with the hefty amount of copper in, I did a Colvic 28 nine plus years ago and its still spot on, took the hull down to bare GRP lightly sanded 3 coats of gelshield and two coats of Copper coat.

Copperbot (now called Coppercoat) eight years on and still going strong. Light abrade with a scrub-all once a year and off it goes again. Would never use annual rubbish again.

weydog

Weymouth UK

I bought a boat in 2003, which had been copperbot'ed (now called Coppercoat) in 1998.

She was lifted and cleaned for survey in 2003 - I didn't see the state of the hull before cleaning -, and again in 2005 (two seasons' worth in Weymouth harbour - shame on me)

Props, rudder and keel which had been painted with conventional antifoul were covered in barnacles and tube worms, and even a rather nice orange sponge, but the hull which had been copperbotted was completely free of any hard fouling - it just had some slimy green algal growth which came off clean with a pressure washer.

Can't say if it will last the ten years, but going strong after seven.

Crianza

East Coast

Crianza was antifouled with Coppercoat from new and is now in her third season. I agree with other posters - it works. The boat stays in the water all year long and I dry the boat out once a year (at the start of the season) and powerwash off the hull. It usually has light slime and some minor weed around the water line. Otherwise it is as good as new. Its quite tough stuff so it resists scuffs and the occasional contact with floating objects.

Mike,

I have just put Coppercoat onto my new 400. The surface was abraded slightly before the boat went into the water to ensure that the copper beads in the epoxy were exposed. After a few days the waterline was green. This is caused by the copper reacting with the water and shows that it is working. If it doesn't change colour at all, I would suggest that not enough copper has been exposed. After 3 weeks in Dartmouth I cannot see any growth.

In the same time our log has stopped working completely. When I took it out (wet!) I found that the whole unit was a writhing mass of life, tiny weed fronds and 1-2 mm long shrimp like beasties. Does any one know of an antifouling compound or medium to stop this?

Coppercoat Antifouling. The boat came out after 8 months and was cleaned easily with a hose, deck scrubber and scourer. Only a couple of barnacles. A jet blaster was not needed. A boatyard hand at Cowes told me he loves the stuff because the bottoms are so easy to clean.

Hi cascars, I took my mates advice and used Coppercoat and have had no problems with it the 3 yrs it’s been on except for a bit of slime when she has sat for a while. you have to key the hull and taking a sander to your pride and joy is a bit daunting lucky for me she was 2nd hand when I got mine my mates was brand spanking warrior 175
