I assure you it is. The problem with copper-loaded epoxies (like Coppercoat) is that they release so little biocide that they tend to be unsuitable for regions of moderate to high fouling. IMHO.

Re: Bottom cleaning without rubbing away anti-foul

I'm into my second year of copper coat in what have to be some of the worst fouling waters on the planet... Coppercoat is about as useless as any other type of antifoul here... The good part is that I don't need to repaint every year!

Re: Bottom cleaning without rubbing away anti-foul

That's probably a pretty good summary of the situation Sharpey. The stuff is not perfect, but then neither is anything else out there. Frankly, in a high-fouling area, you could experiment with ablatives and find one that worked the best - and because of the way they work, possibly better in that situation than Coppercoat. However, as you point out, you would be slapping it on year, after year, after year, and that can get pretty darn expensive, not to mention the hassle. For us, and others I know, Coppercoat works very well, but when the fouling is bad, the fouling is bad. The difference with Coppercoat is you are only scrubbing the fouling off, not the antifouling paint. But then a yard who does good business hauling and antifouling boats every year, might have a different perspective. We just go with what works for us, and everyone has a different idea about that, hence the beauty of these forums.

I guess I don't understand why anybody who keeps a boat in a place where climate doesn't force you to haul for winter, would paint their boat annually.

How often do you think is right?

Considering most anti fouling paints are designed to give good service for 2-3 years, I'd say once every 2-3 years.

Re: Bottom cleaning without rubbing away anti-foul

Some really funny posts:

* "Doesn't look like genuine Coppercoat to me."

As fouled as it is, how could you possibly tell from a picture?

* "Coppercoat is about as useless as any other type of antifoul here.... "

Impossible to decipher what that means. A bare bottom would be the same?

* "However, as you point out, you would be slapping it on year, after year, after year, and that can get pretty darn expensive, not to mention the hassle. For us, and others I know, Coppercoat works very well, but when the fouling is bad, the fouling is bad."

I differ. If I leave a prop or uncoated rudder down for a week in mid season, I have to dive and scrape off hard growth. A good 2-year paint knocks it back to an occation light scrub and no hard growth.

----

Common sense is antifouling boils down to biocide release, and something that last 5-10 years just isn't releasing enough to matter. Heck, if just having copper was enough my grounding plate wouldn't have hard growth... but it does. TANSTAFL. Too bad.

I've seen several boats removed Copper Coat to go back to Trinidad.

----

How long? 2 years should be pretty achievable. I've been doing that for over 20 years, never hauling in the winter.
