Coppercoat vs SeaJet Shogun

[flyingscampi]

My keel and rudder have Coppercoat & the hull SeaJet Shogun so it makes for an interesting comparison after a season on the Medway (without a mid season clean).

I've jet washed the mud and slime off and there was no weed. Some of the barnacles were removed with the jet wash, but the majority wait for the scraper.

I have used Shogun for the past 3 years and this year, although I had no mid season scrub, there was only slime on the hull and no barnacles at all. The prop was a different matter. Massive barnacles and even a small mussel.

Although marina based on the Orwell we were away from home for about 7 weeks altogether, including 2-3 weeks in the Thames/Medway.

Interesting how things can vary.

Lovely picture and it just goes to show how coppercoat is very effective.

I would have liked to see a pic Pre-scrub.

Nice pic but I'm not surprised!

This is what Coppercoat looks like prescrub, not the same boat, this one is mine.

Dont think I've seen a barnical in 5 years.

Mine is coming out in a fortnight after it's first year coppercoated. I hope that the results are the same for me I hope so...

Will take pictures for posterity

Interesting pics but I'd be careful jumping to conclusions. I have no experience with Coppercoat, so I'm not knocking it or endorsing it, but when I hauled my long keeler out of Chichester this year (deep water, swinging mooring, 7 months afloat, no mid season scrub) the keel and rudder looked just like the Coppercoat pic after a quick pressure wash to remove a thin layer of slime, but the undersides of the hull had a lot of large barnacles and much more weed on it - and that's with Cruiser Uno on everything. I think a better comparison would be a mix of Coppercoat and antifouling on the the keel (or undersides) and preferably on the same side as I'm sure the amount of light makes a difference (not a problem on a swinging mooring which changes aspect with the tide but something to consider when in a marina)

I'm planning to conduct a few experiments with different antifouls side by side come the Spring......

All you would've seen is a slimy layer of Medway mud. The barnacles are a lot worse than last year for some reason.

I used SeaJet Shogun for the last 4 years, well I put 3 coats on 4 years ago. We were clean over the summer but had to scrub (with a Scotchpad, in the water) after each winter, but saying that I have no complaints with it at all.

I'm using Jotons' Sea Force 30 now, again 3 coats, watch this space.

I think Copper coat may work but for the initial outlay and the fact that you still need to haul put every year to scrub it it back to 'copper' then its not worth it to me.

I've also met quite a few people who have used it and covered it in self polishing anti-foul withing 2 years as didn't work for them. Like most things in the boating world, you either love it or hate it - me, its a price thing.

I lift my boat out every year and would do so whatever it had on the bottom - need to check all the skin fittings, the prop and shaft, rudder etc as well as give the hull a few weeks to dry. I have copper coat on the hull and the difference compared to my previous Blakes is that all I have to do when the boat is out is a quick wipe with a sponge to get rid of brown slime. No need to abrade the surface at all.

So the advantage is no yearly painting, no antifoul build up and scraping. The disadvantage is - well I cant think of one.

I'm convinced enough to think that if I bought another second hand boat I would put coppercoat or the alternative on its hull rather than use anti foul.

This is a myth. Completely unnecessary to scrub, abrade or otherwise condition it. I had it for 10 years on my keel until rust got beneath it. Never touched it once and had no fouling. Its replacement has now been on for three years, looks like new, still never touched.

Silly question... why the keel coppercoat and not the rest of the boat????

 

[vyv_cox]

It's a complex story. When I originally did it I was living in Holland. I bought sufficient Coppercoat to do the whole hull and hauled out prepared to do it. Unfortunately this was just at the time that the Dutch government banned the application of all copper to boats and the yard I picked were enforcing the rule very strictly. In the end they relented and allowed me to do the keel but no more. I have never been in a situation since where I could arrange to have the hull blasted to do the rest of it.

I used Seaforce 2 years ago, 2 coats, excellent results at first BUT 18 months down the line I had to lift and scrub the colony of barnacles off and now 6 months later I can see loads of weed. Having taken note of the words, 3 years, on the tin, am a bit peed off. I have just bought 5 ltrs of Shogun for half price off Ebay so am interested in the fact it lasted well on yours.

Concur, I have never had to scrub back to copper, its a myth. As for cost, grit blast + CC DIY application, say £2000? divide by 10 (years) £200 a year? Antifoul WILL go up in price plus you have to paint the damned stuff on every year, yes CC needs a scrub, just to get rid of the slime and weed, but you have to dry out or come ashore to change anodes.

Galadriel comes out for the winter soon, first time in 5 years.

Copper Coat may cost a lot initially, I respect that, but long term it is not only at best no more, you only have to do it once and you do not get barnicals

If only it was so simple -

Chaktoura,

I have a swinging mooring in Chichester, and we definitely get sun on one side more often than the other, leading to more fouling at waterline & shallow depth.

I know the boats do actually describe a complete 360, at least often if not every tide, as I regularly photograph the moored boats ( and the marks they leave ) from the air.

At my club, some people are delighted with Copperclad, some disgusted; I think there's a lot of electrolysis - a problem in Chichester Harbour, not boats it seems - and maybe disimilar metal snags with skin fittings etc.

I personally like my boat out of the water every winter anyway, for a chance for the grp to dry, ( call that a myth if you like but I believe it ) maintenance to underwater fittings inc' anodes and the lowered rig...

you don't.

Vyv is right.

My understanding is that Coppercoat does not work well on a drying moorring anyway, something to do with the reaction of the copper and the chemistry of the mud. If I recall the CC goes black and becomes ineffective.
