Ballpark cost of professionally applied Coppercoat?

I am wondering what a ballpark cost for stripping antifouling off a 10m motor boat, prepping the surface and applying Coppercoat should be? Has anyone a recent experience? Do professionals normally provide a guarantee, and how does that work?
My back is saying its time for someone else to look after this aspect of my boat!
 
I had my boat done earlier this year by Shotton Marine (strongly recommended). Bigger than yours at 14.2m so not a direct comparison but may be useful as a starting point.

Blast £2k
Fairing and hull prep £1k
Coppercoat materials just under £2k
Application £2k

So all in, c. £7k. I'd expect yours to be 4-5k.

Yard costs extra but I was paying those anyway.
 
Sticky Fingers, thanks for the input. At this end of the season are you pleased with how she has kept?

Does this sound about right to others?

My previous 39 was coppercoated 5 years before I sold her. Absolutely brilliant. Just a hose off once a year. My new to me Azi 42 was coppercoated in September this year, so too early to comment. The same folk (Shotton Marine) blasted off the old anti foul and applied new coppercoat. They are a great outfit with all the right equipment.

Bit difficult to be sure until the lift in Feb, but no visible sign of any significant growth to date, and wot top speed virtually unaffected on my most recent trip in late September so I’m hopeful all good.

I got some quotes on the Clyde a couple of yrs ago for a 10m sailing boat. Total cost, including lifting, removing mast, moving into shed, doing the work, refitting the mast and relaunching was coming in north of £8k as I recall. I suspect you may be able to negotiate a better price if you wanted it done during the summer - because everyone wants their work done between oct and April.
 
Also on the Clyde and have had a couple of quotes for our 7m motor boat - £7.5k +VAT!

So we’re not getting copper coat. Seems to be expensive up here.
 
Coppercoat general comment :- worked very well on my last boat.
Shotton Marine :- If talking about those in Southampton, I second the recommendation, very happy with blast and recoat they did for me.
Coppercoat work costing :- Will vary a lot depending on season, can't be done outside in the cold months (UK) or in the wet. Inevitably leads to much moving if shed available, or tent building, heating etc which costs as much as the work. Or do it in the summer .... which of course clashes with boat use, take your pick.
Cost :- Will not vary linearly with length, materials cost will of course but not the rest of the job which is where 3/4 of the money lies. Post #2 seems a good ballpark to me for most (average size) boats if conditions allow you to do it outside, obviously that will be very different between Clyde and Solent. Also note in post #2 "Yard costs extra but I was paying those anyway".
 
IMO, Coppercoat doesn't work as well as antifoul.
Have a look at 1 min 10 secs into this video


Thats about 4 months growth in the warm fertile waters of Sant Carles
However, would I ever have Coppercoat again - YES
Coppercoat isn't only an antifoul - it is also an epoxy coat that protects the hull.

In our case, we get free lift and washes.
During those washes, the pressure washer removes the antifoul as well as any fouling.
Being epoxy, Coppercoat doesn't get removed with the pressure washer.
In my case, it lasts about 10 years before requiring "topping up".
 
OK so practical brain, click on. A 10 meter boat will lose say no more than 20% fuel efficiency when it's hull has a coral reef growing on it. So at say 30 litres per hour cruising speed that is 6 litres per hour wasted, or about 8 quid an hour, the average boater does 50 hours a year thats £400 per year wasted...at most, does that warrant 7 grands worth of copper coat, AND you will still have to pay for a lift out once a year to "hose off" the hull. Not for me, the maths doesn't add up.
 
A quick note to say thanks for all the input. I am sitting down with my marina to discuss it tomorrow.
I am a little puzzled how Jenny Wren got in that state. I have been around several Coppercoated boats and never seen anything like that!
Thanks again.

30 litres an hour 😳

This is a Mobo q. My old lady uses about 200 / hour at planing cruising speed. Less at tickover obviously.

Also I disagree with your 20% figure, but that’s not the point. It’s not really where the savings are. They lie in elimination of annual antifoul and lift costs. In my own case I reckon the break even is less than 4 years.

The Coppercoat can be de-slimed by a diver for a few hundred quid. A lift for me is £1200. Antifoul (professional application not DIY) is at least another £1500.

Our marina has particularly heavy marine growth. Very warm waters most of the year, coupled with our location - tucked in behind the Ebro Delta where they grow the rice for Spanish Paella. This all leads to a fertile area where the crustaceans grow well - great for the local food.
I choose to use Coppercoat - if you use conventional anti foul, you don't get as much growth. Hence my comment that Coppercoat isn't as good as anti foul for the protection of growth.
The marina give us a free lift and pressure wash per year and Coppercoat doesn't get washed away with the pressure washer.
So a quick wash before we go anywhere is a "no brainer"
You will have noticed that I don't treat the props/shafts etc - for the same reason.

IMO, this is a small inconvenience for a nice and very cheap place to keep the boat in the Med - just 100 miles form the Balearics.
As with all locations, you have to consider all the pros and cons - we have a nice modern marina located right next to a fantastic lagoon where we can pop out and anchor for a few hours. Often watching the sun set over the mountains with some fresh prawns and a glass or two of cava.

This was earlier this year - just popped out for lunch on the hook.

That is the wrong way of looking at it. The savings are in not replacing conventional AF every year which on my 10m boat is £200 minimum for materials and £400 for yard labour. If you DIY application blasting and materials is about £2.5k, professional £5.5k. So 10 year life DIY breaks even (and saves a day in the winter crawling underneath). Professional more than breaks even. If you want to add your £400 a year fuel savings you gain £4k over 10 years. However not sure why anyone with a powerboat would tolerate that losss of performance from a fouled hull!

Fouling…. Some folks just don’t get it, and cannot be told. Coppercoat here. I did the maths, and came out way ahead, and we use £20 in fuel a year. We scrub our own through the season, keeps Chiara fast for racing. We had ours done about 3 years ago, very pleased. It’s not fouling free, but it’s no worse than other coatings and is infinitely scrubbable. Ours was a third of some oth those quotes to get done. But that was already craned out, and we had previously stripped 20 years of old crap off so she had just epoxy primer and 1 years coat of conventional AF. Not much prep to do, no filling, I’d already done it.
 
10+ years ago, when I had a 10m motor boat I was spending £1k-ish a year on anti fouling. I wouldn’t dream of doing the work myself as I have no wish to ingest or otherwise absorb some pretty vile chemicals.

For a similar sized boat today, spending £7k on coppercoat to have done with anti fouling (other than having the hull scrubbed maybe twice a year) for the next 7-10 years would look like a good deal to me.
 
I had my 37’ boat coppercoated - it was a no brainer as she’s 23 years old and as Hurricane said, it also protects the hull as it’s epoxy. It was as much about the hull protection as it was antifoul. Cost around 7k and I think an investment in peace of mind

As you're talking about me Ill reply to you, I go get it and my maths are correct but if you're someone that likes to copper coat his boat then good for you, but financially it makes no sense. And BTW if you you think that people on this forum believe that you use 20 quid of juice a year then I think you're deluded or just being silly.
