Is anyone out there really pleased with their antifoul this year? Seems to me, in Haslar anyway, that the warmer weather has resulted in lots more slime and general growth.
Time for a change maybe.
 
I've noticed the same. Even with new Seaforce on in May, the boat's got a beard now.
 
Coppercoated three years ago and very pleased with it. Doesn't stop growth entirely - but I use diving gear to spring-clean it at the start of the season, then I have a nice smooth hull for the rest of the year. Well worth the initial hard work and investment.
 
We had the Haslar Sealift put 2 coats of Jotun Seaqueen on3 seasons ago.

It has been pressure washed every season since its aplication-not sure I'll get it done so often next time- and lasted untill we put her to bed for the winter at the end of last month.

No more Seaqueen for leisure sailors, so we are to try their recomended alternative next season.

Very pleased with seaqueen-3 seasons will do for me!

Whatever the problem is, it isn't just the temperature. We have used mostly UK bought antifouling in the Mediterranean for the past ten years where it performs reasonably well.

Some pointers -
We rarely stay anywhere for more than a few days but if we are marina-bound for a week or more the fouling starts.
There is little agriculture, so not a lot of nitrate run-off.
The best we have used was made by Plastimo, expensive but all we could get thanks to a truck drivers strike. Otherwise there has been little to choose between various International, Flag, EU45 and other makes.
 
Ever since Jotun stopped supplying seaforce / seaqueen to no commercial outfits, I have just about given up on finding anything else that works.
 
Micron Extra in Portsmouth harbour has not been as good as previous years it seems to me, I put that down to the warmer weather. Been jet washed twice this season and it really needs doing again.

I put coppercoat on the rudder last winter (beceuse it was off the boat anyway so east to do in a warm garage) this has so far not performed as well as the micron extra but I'm hoping next season will be better. I have had slime on in after a couple of weeks and weed growing after 4 weeks. I gather it takes a while for the copper to oxidise so I'm being patient.
 
Very best antifoul I have ever used came from EBAY .... half of a 25 litre drum of something I'd never heard of (but from a major manufacturer). Lasted 2 seasons easily. Sadly supplier has vanished. Never did know the formulation :o
 
Seajet 033 Shogun.

Applied (2 good coats and more on leading edges / waterline) October 2012.

Boat used regularly all year.

Lifted September 2014 (so almost 2 years later) for quick wash off and now back in.

I was impressed (these are the before wash off pictures!).

Chichester marina based.

Folding prop didn't look so good though (reason for lift).....

We are just around the corner in Premier, Seajet 33 didn't work this year. Last pressure wash was 3 Sep and I have 3" fonds of weed on the water line again. Back to Micron Extra next year.
 
I am also in Haslar and the Micron, (two coats applied in May plus extra coat on bows, keel and rudder), is doing well. It looks a little weedy when boat has been idle for a while, but most of it disappears when I move the boat, even on a short trip round to GBY and back. I'll use the Sealift in the near future for a scrub off, but mainly to change the anodes on my Volvo folding prop which do not last a year.
