G'day Chris.
First you must ask others in your area what sort of performance they are getting, but make sure you only ask the ones who use their boat in much the same way you plan to. It's no good comparing a boat that dries out with one in a marina for instance, now with one that never moves, or is on the move every day.
When purchasing antifouling paint, check the can for the % of working ingredients, cheaper antifouling can be a watered down version of a good one.
I hope this helps..

There is no 'best' antifouling, as performance differs round the coast, even from port to port. Look aroiund your local yard(s) at haul out time, and see which boats are coming out cleanest. Enquiry of the owner/yard will soon show up what performs best in your locality.

You will find that people will go on for ever about researching different products, etc. but I am not so sure that different products work any better in different regions. I have a Macwester 30 on the Deben in Suffolk and cruise the East coast. Boat also spends some time on the river Trent at Newark. I used XM antifouling which I consider worked very well. I did get some weed on after the middle of the season but I beached the boat and scrubed the weed off in no time at all. I will use XM again next season.

I'm also on the River Deben but at the Ferry, and use Flag Antifouling at £39.99/2½litres delivered, 2 coats, usually with a mid season scrub. I find it OK but might change to Jotun Sea Guardian next season as have just found a source much cheaper than Flag!

If you spend some time in fresh water, and get actual weed growing, then I think your antifouling has failed you.
I have used XM and found it to be almost useless. You should certainly expect - especially if you are in fresh water for some of the time, to end the season with only slime - not weed. XM is also very soft, and cannot be scrubbed lightly mid season. I also found that after 2 seasons, it became so flakey that I had to go back to the gel coat base.
I used Blakes Seatech for one season - total disaster Very expensive
I then used Blakes Titan - Very good, but too soft even for light brushing around the waterline. Expensive
This year I used SeaJet - very hard - can be brushed mid season, - but didn't need it - Total success - slight slime after 9 months. Also very cheap. so same again next year.
At the end of the day, ask locally what works, as areas vary enormously.

Also on the East Coast...
...on the Colne. Used XM last season with excellent results, used it again this season just gone and had to scrub off (well the choice was either scrub off or use a strimmer!!) mid way through the season. Re-coated between tides, and when she came out early November there was just a very light coat of slime and a few barnacles.
Think that next season a change is due. Come on Dick, spill the beans where is your source of Jotun...I have heard excellent reports of its efficacy!

I have been told that Blakes Antifouling paint and International Antifouling paint are not compatable with each other, and if I try to use one over the top of the other they will not bond unless a barrier paint is put on first. As I do not know what antifouling paint is on my recently acquired boat can anyone advise a course of action. Or should I put on the barrier coat.

There is a lovely book by Tim Severin of Brendan ( leather boat fame) concerning a voyage made in an 80 foot boat from Oman to China. The boat was a wooden medieval replica and the journey took 7 months.
They used lime and mutton fat mixed together as traditional anitifoul which seemed to work very well, specially with regard to Teredo. They attached pieces of untreated wood for test purposes, which disintegrated with little hand pressure at the end of the voyage.
Dare someone to give it a go !

Seajet 033 is as good as any and better than most regardless of cost.

Whichever antifoul you choose...
Whichever antifoul you choose, you'll only get good performance from it if you paint enough on. You'll find that 2 or 3 good coats applied by brush will keep weed at bay much longer than several coats applied by roller. Bearing in mind what a filthy job it is anyway, spending a bit more on antifoul is a worthwhile investment if it lasts longer before you need to touch it again!

Jimtar: -Its not a good idea to put (expensive!) antifouling over a previous unknown coat, as if it is incompatible, the new stuff may not stick and will fall off again within a couple of months use. When you have decided what to use, check the manufs recommendation for a barrier coat before you start. Remember too that although you can (usually) put 'soft' antifouls over 'hard' ones, you can rarely put a hard coat over an older soft one. As a rule soft antifouls are the ones that erode away as they are used, so are unsutiable for higher speed craft.

Blakes say you don't - that is provided that the underlying antifouling is not already flaking. I originally had internations micron - changed to XM3000 (scotts blood in me) had to reantifould twice in season - ended up with all flaking off. I think modern antifouling cannot be applied between tdes - this may have been the casue of the flaking. or as many others have commented - it may be XM problem - very thick, and very soft. (and useless)
I then scraped back to gel and applied Blakes Seatek - disaster - blakes gave me a complimentary cans of Titan - which worked a treat, straight on over the top. the next year I tried Sea jet, rough sanded the whole bottom after pressure spray - which moved most of the Titan as it is quite soft, applied seajet and at end of first year there is no sign of any flaking and no weed at all.
It is also worth putting a different colour on each year so that you can see how much to rubdown each year.

After many years of using Micron CSC I moved to Seajet Shogun last season. I abraded the micron after powerwash and applied 2 coats of the Seajet, roller plus brush around water line and leading edges. When lifted slight slime and will only require one coat this year. Location Portsmouth Harbour. I think from memory Mr Robb is Plymouth? Any other locations tried this product?

I have applied XM for the last 3 years between tides with no problem at all. It has also worked well for me. That said I applied it on top of the old copperbot so it hasn't had a compatability problem.

Oh well - that was XMs explanation of the flaking!
It really is a local thing as to which works. I was in Chichester when I used XM, and Titan - this year was in Plymouth with no fouling on Seajet, but the comparisons are really worthless.
