Coppercoat effectiveness in Mylor, SW England?

[Maxra]

I'd appreciate some views/experience on how effective Coppercoat is in SW England, specifically the Mylor area of the Fal? Thanks, Max

Depends on how you define effectiveness. In terms of life it does not matter where the boat is located, provided it is properly applied. As an antifoul the only type of location where there might be problems is of the boat sits in mud at low tide.

There must be hundreds of boats in the Fal with it - Mylor Yacht Harbour is a major Coppercoat application centre. Suggest you ask them (although they will probably say yes!) but will likely direct you to local owners and local boats.

I had 2 seasons in the Mylor area after Coppercoating before moving the boat away, and was quite satisfied with the performance of the Coppercoat. Fouling there can be quite high with the run off from the fields but there was nothing that didn’t wipe or pressure wash off. Would I recommend Coppercoat for the area? Yes.

No matter whether you diy or employ someone else, DO make sure that you or they adhere rigidly to the parameters for preparation, drying (get satisfactory moisture readings before moving on) application and curing. If getting someone else to do the work, watch them like a hawk.

We are having ours done right now. I trust the guys absolutely, but only I know exactly what has previously been done. This has been partly communicated by messages on the hull in whiteboard marker. I'd like them to have the best chance of a perfect job.

My boat is in Mylor - and, apart from cruising every summer and 2 years in the tropics, has been there since 2005. We had the boat copper-coated by Mylor in 2015. The copper coat has adhered perfectly and I have no problem recommending Mylor to apply it. They also touch up those gashes I have crated from time to time!

As for effectiveness at Mylor / the Fal it's ok, but not brilliant. I find I have to burnish it a bit (slight sanding) every winter, and dry out alongside around the beginning of July every year to scrub off. Since I have to do this for the prop anyway it's no real trouble. What I am scrubbing off is slime not barnacles or weed, but If I don't do it the fouling is pretty severe by November when we haul out. However I don't intend to return to conventional antifouling. Feel free to 'pm' me if you like.

I sail in the South West, Plymouth based, and find Coppercoat fantastic. With the boat in the water for 24 months during COVID and moving very little I had her lifted and jet washed. A thin film of slime was removed and the guy who did it said it was the easiest job he had done.

The Coppercoat was applied by Mylor.

I would only add that after coppercoating you will get some slime and need to reburnish now & again but you shouldn't get anything that well & truly attaches itself to the hull even after 10+ years. That's been my experience anyway but it seems some people mistakenly have the impression that if you coppercoat then nothing whatsoever will end up on the hull. I think properly applied it's brilliant stuff but there are some who disagree...

We like to beach, and wipe down, so hopefully its ideal for us. A quick crane out once a year for the rest, is all we want. Not expecting zero maintenance.

I've just had a bottom blast (!) on the Orwell which is also a prime growth area and found on lifting that after nearly 12mths the hull was 3-4mm deep in slime with some pendulous slimy growthsto 10mm or so but where the coppercoat didn't reach - the bezel of the log impeller and the propellor boss the sea-squirts, jelly things, gloop and gunk were a solid slithery mass maybe 60-80mm long.
The slime came off easily with a pressure washer and there were no barnies at all.

As said above, it doesn't stop growth but it certainly severely retards it.
I'm very impressed with the performance of coppercoat.

Thanks all for that info!
