As the time looms nearer for another coat. How has your anti foul performed this year? This season I used Hempel Tiger Extra, disappointment is an understatement! This has to have been the worst year for me so far, I'm based Hayling/Chichester and have had to scrub twice so far. This isn't just a light coating either I'm talking seaweed on steroids. If for any reason I wanted to start farming seaweed I know what I would use.

Whats your poison and has it worked?

I have been using Tiger Extra for many years and it has always performed well. You have to find what works for your local area, for Mylor it's Tiger Extra !
 
I usual use whatever the eroding antifoul the local chandlery has on special offer - usually 3l for the price of 2.5l.

This year I gave EU45 a go as it looked to be a 'better' formulation. Very disappointed. The yard reported that my boat seemed to have more weed and slime than others yachts they had slipped; but no barnacles.. I won't be using it again. Fouling in NW Scotland is not usually a huge problem as there are no significant rivers with farming run-off.

Thanks for the comment on Tiger extra - I was considering that for next year.
 
I used tiger xtra. Boat went in in march and by August it was losing effectiveness & a layer of slime/weed was slowing me down so I did a scrub off put and put a thin coat of flag on to see out the season. I think the coats of tiger xtra I put on over winter were probably a little thin but it did seem to work well up till august. This is similar to cruiser Uno I used year before last which worked well but usually stopped working by end of summer meaning a scrub off or a slow sailing autumn.
 
Almost all brands of antifoul contain the same sort of ingredients. So satisfaction with antifoul is directly proportional to the amount of the wretched stuff you apply. Manufacturers recommend minimum quantities - these are the minimum for effective performance. I know it's stupidly expensive stuff, but people who put two thin coats on with a roller are often disappointed. I've always brush-applied, to get more on, and have followed International's recommendations for the quantity of Micron to apply, and I've never been disappointed (and that's leaving the boat in the water for 2 years between antifouling).
 
I used CopperCoat, this is the 3rd season.
The performance was slightly better than last year, no barnacles, which we had last year.
There was quite a lot of slime, on a clean hull I get just about 7 knots at 2,000 rpm. This had dropped to about 6.4 knots by the end of the season, Launched end of April out end of September. No mid season scrub. Location NW Scotland on a swing mooring.
The prop' was polished with Autosol, to a bright shiny finish, by the end of the season it had a very light slime on part of the prop' and the rest was still shiny.
I still don't think CopperCoat is as good as Micron Optima.

I will be using Jotun Seaqueen again, after 5 months only a small amount of slime on the rudder & turn of the bilge, the keel is clean,blue a/f
 
Here is my hull on haul out - notice the small square where a wedge was placed at the top of a supporting shore and I wasn't able to anti foul that before lift in - i.e. that patch has the previous years anti foul on it only!
To give a sense of scale, the 'long threads' are about 5 to 10mm. Where I anti fouled just a general stubbly growth a bit like suede. We were still making 6 knots easily at end of season, (32ft sail boat)
The 'new' stuff was Gael Force own brand, 5 littres at about £65 IIRC did the job. It is made for them by by International. Two coats applied by roller.

I am also on a swinging mooring in Mylor.

Tiger xtra has worked for me in Poole. I traded 'down' from Blakes 2 part Ocean Performer 2 seasons back as an experiment and have come to the conclusion that the Ocean Performer was overkill. Stargazer had minimal slime only when lifted at the end of last season and looked similar this time round when I went for a Friday evening dip at anchor in Worbarrow . Two roller applied coats each season.

I used some cheap old stuff - XM, I think - which I laid in from eBay a couple of years ago. One coat. Hull looked freshly done when she came out after five months in the waters of the Clyde and the west coast - barely even a hint of slime. In the past I have used Nautical for the same reasons, in the same quantities and with the same results.
 
I used Gael Forces own band this year but the hull has a layer of 4" green weed all over it. Last year I used Seago which seemed a little better although that might be down to weather. Even the prop had some weed on it, despite the boat being used every week and that isn't down to antifoul.
What I did notice was that the Seago stuff turned the water blue when rubbed but the Gael Force stuff didn't come off so easily. All the fouling seemed to happen after the end of August.
I think the only fair comparisons that can be made are between boats on the same moorings over the same period.

Why this year?

I know it can vary from area to area but paint manufacturers must love people who antifoul every year WHY??

I use two coats of Jotun on top of one coat Jotun primer and stay in 2 years min without problems usually just slime at lift out, after 50 years of boating
as far as antifoul is concerned I am a firm believer that 'you gets what you pay for' :)

I suspect that in my case two four day immersions in the limpid spring water of the Crinan Canal may have helped the paint do its stuff. Mind you, last year was just as good and we didn't do the canal.

Im on the clyde too and also spent time on the canal, don't know where all this green weed has come from though. Can XM really be that much better or is there something else going on?
 
I have been using xm cx2000 from eBay. It has been on just over a year and there is just a darkening of the paint. A bit of crud can start to grow at this time of year but as long as the boat gets used regularly it comes off before it can get established. There were a few wispy bits starting to grow on the waterline yesterday but after a 60 mile blast it has all gone again. It will probably do until late next summer.

Sorry PVB But if you think they are all the same, why are you using micron extra and not something a third of the price like Flag or XM?
