Antifouling recommendations

[AllanG]

Hi,

Having just bought a Nimbus 320, I would welcome any recommendations for antifouling I should consider, bearing in mind the boat is a semi-displacement (13-17 knots cruising), and will be moored in the River Hamble.

I was using International Micron Extra on my previous sailing boat, to good effect.

Thanks for in advance!

Seajet Shogun is the best antifoul for use on the Hamble.

I don't recall anyone on here ever being dissatisfied with an eroding antifoul in the UK, in fact everyone seems to praise the particular brand of antifoul they use, which suggests to me that they all work pretty well. On that basis, i'd choose whichever one your chandler is doing a deal on.

edit: Definitely eroding though, not hard, at your speeds.

Antifoulings are different, but of you pick one of the leisure boating varieties, suitable for your speed range, you should be OK.

Some think that 'commercial' types are better, but they are designed for vessels that sail every day at their best speed - not exactly the life of most liesure boats.

I recently stumbled over http://www.eu45antifoul.com/home_eng.php who appear to sell at a fair price - including delivery.

Can't say if it's good, though.

I have tried various types, international, blakes included. Found that EU45 and Jotun Sea Queen seem to work well.

Works very well for us.

Sarah's boat is on the hamble - she seems to disagree, as do I.

“Our experience with Coppercoat has been fantastic. In all the 14 years we’ve never had a barnacle, seaweed, nothing…. The original claim for our Coppercoat was that it would last 10 years and many people were sceptical. Our test proves the doubters wrong.”

Sorry to say but our Coppercoat is five years old and does not work. Last year we lost six knots in six weeks after experimenting with no rub down at lift out as advised by coppercoat. (Big mistake) This year we had a fairly agressive dressing of the coppercoat and have lost five knots in eight weeks. Now Coppercoat advise it needs a light re-paint every two years to keep it active!! Dont yet know what that will cost but it sounds expensive and its all adding weight. I have no issue as I didnt pay for the original application but its a pain trying to find out how to make it work. Yes I now before people say it - it could be partly build up on props, shafts, P brackets and rudders.

We have been using this stuff

http://discountantifoul.com/

to very good effect. Antifouled the boat in March and we still have no growth on the hull. Very good stuff and a very competitive price. We picked a can up for £20 from the manufacturer at a local boat jumble as the can was slightly damaged. One can is enough to give our small boat 3 coats and should last us next season as well.

I used cruiser uno this year, worst mistake ever for use on the Hamble, the weed was growing on it after 4 weeks!, previously I had used Jotun that came at the right price and it lasted really well, the problem is all these do gooders like the eu that are telling us what we can and cannot use for the environment.

So a 5 litre tin of paint with all the right stuff in it to stop weed growth is a no no but an extra few hundred gallons of wasted diesel poluting the skies is ok???? I just dont get it.

Went out this weekend 300 rpm down and maxed out at 18.5 knots not great at all.

All I can say is that having been on the Hamble for best part of 12 years, I have used Seajet for at least 8 years and have found it better than most. Let's face it, most of the active ingredients have been watered down anyway.

i can only speak from personal experience and would use it again.

Wow!! Amazing how it varies so much.

We've used Crusier Uno for 2 years now on the Hamble (based @ Mercury) and each year since using it our hull always comes out virtually clean. Much better than our stuff we've used before.

We get a little growth around the water line that gets the sun, this soon scubs off...... won't be using anything different next year!!

Paul, that's strange, Cruiser Uno usually comes out well in the magazine tests. Did you stir it properly before applying?

Hi nick yes I did, im very surprised at the results as I asked around at what to use, the skirt on the stern and starboard side is amazing, I have brushed it all off twice this year now, it just comes straight back, I have not had the camera on the props but by now id say there pretty messed up with barnacles and calcium build up, but 18.5 knots from 29 is a hell of a lot to loose.

I went on to using cruiser uno about 5 years ago after KevB recommended it.

I am not often in the hamble but I am around the solent and have found it works really well.

Lift out/scrub once a year.
repaint every two years.

No build up, it erodes off, fairy quickly above 25 knots but its not often we go above 25 and only for short spurts anyway.

These were taken prior to jetwash after 14 months

Paul,

Sounds like you need to give Sealift a visit for quick brush up. Must pay for itself pretty smart'ish if you're only pulling max 18knots at full power. Think of the extra juice being burnt.

I changed from Blakes to Uno last time and the Uno was worse by a long way for weedy waterline growth. Only a couple of the barnies thou. No build up also.

This year on Internationals advice changed to Micron Extra and apart from the slightly lighter colour than the Uno once dry I'm delighted. Hamble based with little current on berth. In fact I have made a spread sheet as nearly all the boats on my pontoon came out within 6 weeks of my lift. All sorts of paint used.

Plan is to look in the spring and table the results. Will post on here once done!

Not suggesting it's a bad product or doubting your experience, but you were quite definitive that it is "the best"

To me the best not only stops fouling but lasts best part of 20 years, makes your boat go faster and helps protect against osmosis.

Only 1 product can prove all 4 of these things.

This advice is nonsense. It would do more harm than good.
I'd wager anything this advice did not come from Coppercoat.
Are you sure you have Coppercoat or something copper looking.? Sarah Norbury would hardly fabricate the performance to publish in a magazine would she?
I suggest you get some proper advice.

I had stern words over what the stuff is on my hull. I too reckoned it had to be be "the other stuff" but I have copies of the invoices so unless everyone is telling fibs about what tin the brush was dipped in, it is coppercoat.

You sort of lost your wager. The advice to slap a new coat on came from the Coppercoat appointed local agent who discussed it with Coppercoat. Mind you I dont really go too much on Coppercoat advice. They advised not even dressing it last year, just a pressure wash. Big disaster.

I am not suggesting anyone fabricated anything. I dont know the lady and didnt see the article. All I can do is report on what I find. During discussions with Coppercoat as with most suppliers there are always ifs and buts. They say maybe it was not applied correctly, maybe it was a wet day or hot day or cold day, maybe not enough time between coats, maybe not enough coats, maybe an "R" in the month. All I know is it dont work.
