My boat came out of the water a couple of days ago, having been in since May. She has been on a swinging mooring in the Clyde for all but a couple of weekends and five weeks away in the summer. Before launching - well before, in March - I gave her a single coat of "Nautical" antifouling, which is now branded Akzo-Nobel but used to be International, in very small print.

She came out almost completely clean, with just a little slime. No weeds, no barnacles.

I thought I'd pass this on - "Nautical" seems to work well for the Clyde, and is one of the cheapest antifoulings around. I can supply a picture of my bottom, if anyone wants to see it, as the Minister for Civil Society said to the journalist.
 
Thanks for the tip. Last two seasons near Oban have been really bad for fouling. Not sure how it compares with the Clyde. I always used the cheapest antifouling I could get and had good results with Seago in the Clyde and near Oban for many years. Last season the boat was definitely struggling and had quite bad growth when lifted. I changed to Blakes Tiger this season which was much more expensive. When the boat was lifted last week it was even worse with a 6 inch beard of brown weed round the waterline and over the rudder. Not very impressed. Anyone know of a suitable place near Oban to dry out for a mid season scrub next year.
 
Very interesting, I've been on a mooring at Rhu (Upper Clyde) with International Micron Extra 2 for the last 4 seasons.

Last year was waterline green slime & slight slime underneath, This year was big clumps of barnacles....serious clumps up to a foot square.

Apparently I'm not the only one, other boats having the same issue. Something to do with dry summer, less rain which equals more salt in the water which the makes the little suckers thrive or so i've been told

"Reliability is not a matter of truth, though it helps. It's a matter of having data you can rely on, and a few self-reported stories just don't have the statistical significance needed. That's why I don't put any more reliance on the accounts of Coppercoat failures than the accounts of Coppercoat successes - I don't doubt the sincerity of the reports but they just aren't enough to lead to a sound conclusion." :)

Of course. I am offering no more than an anecdote, but one which might be useful to someone in a situation similar to my own. I certainly would not advise extrapolating it to elsewhere, or trying to draw any general conclusions. Neither am I trying to sell extremely expensive antifouling.
 
I used Seago as usual. This year a small beard of short thin weed just below waterline, but not very deep as far as I can see.
I've not seen barnacles for many years, though occasionally see tiny mussels in the rudder skeg slot where I've not slathered enough Seago on.

btw International is just one of the many brands of Akzo Nobel. Same company!

This year I used the same micron extra 2. Boat out of water from Rhu on Monday bottom is perfect, what a result. I had put some on the prop at beginning of season and there is a small area with some barnacles on it. I had used Hempel Tiger Xtra last year with poor results. A couple of touch up areas before going back in on March, should last another season.
