Some forumites are aware that I have had some issues with the application of the Coppercoat to my boat.

Following remedial work by Mark and his team I'm pleased to say that my bottom status has gone from grumpy git to happy womble.

Thanks.
 
It was nice to check the hull this weekend to see just a light coating of slime and a green band above the waterline ....
yes - just a few months after Mark stripped her back and did the coppercoat....

What was the problem that you had and how has it been resolved? I am having problems with the Coppercoat on my boat and am struggling to get it resolved, weed growth is terrible despite the boat being lifted and jetwashed twice this year.

Couple of questions
When was it applied?
When was it last abraded
Was it Coppercoat or an alternative brand?
How often do you take the boat out?

I'm no expert - but if you're getting significant weed growth then I would think the copper isn't doing it's job. We've got a bit of slime/weed visible just under the waterline, but that will disappear quickly after a good windward bash ...

Hi Fireball

It was applied in April of this year and i assume that it was abraded at this time. The boat went back in the water in May and by the end of June had weed growth. The Coppercoat (And it is Coppercoat) above the waterline had not discoloured. I had the boat lifted and jetwashed in July as I was told that sometimes when the water is warm that a slime can immediatly develop that stops the CC reacting. Sadly no change with weed growth again, boat was lifted in September, jetwashed and back in the water and I now have weed growth again. The CC above the waterline has just started to go a very light green in places but certainly not the verdis colour that I was expecting. Even taking the boat out in some rough seas for a 70 mile sail did not significantly reduce the weed adhering to the hull.

The whole thing is becoming quite demoralising!

Thanks

Chris
 
I have just lifted out 7 years after applying Coppercoat, and staying in the water for 2 years this this time around. The hull had the normal thin layer of slime, and was easily pressure washed off. This was in an area of very high fouling. Non Coppercoated areas, ie the prop and bowthruster were very heavily barnacled and musselled. I applied the Coppercoat myself. I waited a week or two for a few dry days to get the hull really dry, and then applied the Coppercoat on a nice warm day and followed the instructions to the letter. I did not abrade the hull before launching. There is always a greenish layer just above the water line which appeared shortly after the initial launch and looks about the same now. There have been several discussions about Coppercoat working or otherwise. All I can say is when the instructions were followed it did the job and will definitely use it on my next boat.
 
Ours was done during June (I had a problem with a thru hull fitting so had to come out anyway) - and other than the pressure washing sounds the same as you - we've just gone green above the waterline - otherwise it is the chocolate colour.
We have a thin layer of slime that can be easily wiped off (tested at the bow) but I've yet to brush or wash it off ... I'll probably wait till the new year now.
I was told that it does take a while for the copper to become effective - but yours doesn't sound quite right ...

I was also told that the copper takes a while to become effective...........question is how long and how many lifts are required? At this rate there will be no saving. Job has been a total nightmare..........at this rate am going back to standard antifoul. Will try once more to get this resolved but frankly going on performance to date sadly I do not hold out much hope.

A question I cannot answer - however, if you PM Ellesar he may be able to offer some advice.

The surface on ours feels very smooth - I don't know if this is what prevents too much sticking to the hull, but I would think it should help ...

We did ours in April, two coats of Corro-Tech on the keel + two coats of solvent free epoxy on the keel and hull + Four coats of coppercoat, all applied over three days and launched 10 days later.

As others have said we had a thin layer of slime from July onwards. Boat is now ashore. No sign of rust in the keel + hull is a stunning shade of green ... Overall, very pleased.

I wonder if it is down to poor application? Think it is maybe time to contact coppercoat themselves and get them to check out what has been done and see if they have any recommendations.

I like the idea but would like to know more about the budget justification. I reckon that the operation costs me around €275 each year for a 9m20 boat. (That includes lift out and in, labour and materials).

That's cheap ... a lift out for us is ~£400 a time then you've got to add materials (tend to do the labour ourselves). Then every few years you may need to peel back the old A/F if it hasn't completely eroded - which is just hassle....
 
I applied coppercoat nearly 5 years ago and other than lightly abrading the sides a couple of times have done nothing. Green hull all over and never more than a slight slime.

I found somebody who is willing to do it for €140. Mind you we have it down to an art and scrub, jet hose and painting only takes between 2-3 hours. The lift-out is about €75, including a week-end on land, and the rest is anti-fouling, brushes, rollers and shaft anode.

Ditto.

Only one year after application, so not turned green yet ;)
Just the slightest hint of slime
