I normally use Sea Jet 033 which is really good but £90 a tin is pricey. Has anybody had good results with SVB,s Seatec Standard Pro Gael force or Flag?
 
I cant speak highly enough of Cu-Pro - the price is good, but I am not sure what tin size you are referring to.

I say that purely as a very happy user, and can vouch that it does last 2 years. I have been using it for some time now.

A glowing recommendation, but where do you berth/moor please?

I've always found different areas of the UK require different antifouling for best results against the local wildlife (Coppercoat and the north eastern reaches of Portsmouth harbour water having the same effect as applying Fisons to the underside of my previous boat)

SML paints only have 5L at £100. to exspensive for me, rather get 2.5l
 
Used Flag for years. Very effective particularly against barnacles - that's the Performance Hard. It is good because it only needs 6 hrs before immersion.

...but that's not that cheap, right? Looking at Flag Cruising which is budget...and if I understand correctly is the same as Gael Force.

I've no idea if it stops fouling but I've applied Flag Cruising this year, I ended up putting two and a half coats on a Coribbee. (5 litres. ) Maybe more expensive brands go a bit further in which case maybe Flag Cruising isn't such good value.

A definitive guide to antifouling which allowed an accurate comparison would be really handy, seems a total leap of faith to me.
 
5 litres is the same quantity of paint (Micron 350) as we put on my 34" tub which was performing well enough before the boat was hauled out about a month ago.

From memory we put around two litres of Tiger Extra on the OH's Coribbee

Yes, I was expecting 2.5 litres to do the whole boat, but then the old AF had really had it so I'm not sure that's conclusive. Also I guess I didn't *need* 5 litres, but one 2.5 litre tin wasn't enough so I had to buy a second to finish off the second coat leaving half a tin. Needless to say I wasn't going to bin half a tin so the last half tin went on the boat. So call it 3.5 litres rather than 5L.

We have not had any noticeable issues with keeping part used tins for use the following season.

I'd have to store it and someone would find a way to kick it over or I'd forget it. Plus it's a bit like anchor chain - it's doing more good on the boat then in my garage. The paint will still be there next time I apply AF, IYSWIM.

In short I concluded that storing 1.5L of AF on the bottom of my boat was better than storing it in my Garage.

I might be wrong about that, but that's what I concluded on the spot on a dark cold winter's day after Xmas.

What *was* a crime was the boot line paint which cost me £25. I used about 100ml of it. This I did intend to store but the lid bent and I couldn't seal it back on. I ended up skipping 900ml of it. (I did consider painting it out of sight low down on the hull to use it up but I was unsure about painting hard over soft and so proud of my lovely red paint job that I didn't.) There were tears over that.
 
Gael Force is rebadged Flag, some tins are just wrapped with a GF logo. I use it because my boat does not spend all its time in the sea and the transition between fresh and salt water is an effective way of killing marine growth. It is less powerful than Shogun and considerably less colour fast, navy blue becomes light blue in about a month. It does erode away satisfactorily so the build up from year to year is nice and slow.
I think it would be fine for a boat that is under way regularly and is not kept in a particularly high fouling location.
 
5 litres on a Corribee is overkill. I use 2.5 litres a year on a 35 ft fin keel monohull, kept in a high fouling area salt water harbour. Thinned down that gives one rolled coat all over plus a second for 6-8" round the waterline and on the leading edges of keel and rudder. Boat in water 10 months last year, minimal fouling on liftout, mostly slime. Last year used Micron Extra, this year just relaunched with similar quantity/method of Shogun 33, that I have used several times before. I buy whichever of Shogun 33 or Micron is on offer cheapest each year. Performance seems very similar.

My view is better a thin coating of effective AF than a thick coating of less good stuff. I lightly wet sand each year after liftout which also slows down the buildup of AF. Getting lots of AF off a hull is a vile job, unless you pay quite a lot to have it gritblasted.
 
Many years ago I used to antifouling lots of a mooring operators customers boats with the cheapest to the most expensive. Often had paint left over so one year I had enough to do my own long keeler.
I used what I had most of around the waterline and because some paints reacted badly to mixing with each other I painted what I could with whatever colour until I moved on to the next can. Ended up with so many different brands and colours all over the boat, but it was about the job it does, not what it looked like !
The following year on the grid I saw that it made no difference whatsoever what antifouling was used as the whole boat had an even covering of weed.
Now I just use whatever I can get the cheapest as the most expensive does no better.
I recently aquired a 20 litre can of interspeed 6200 at garage clear out for £10 !!!
Google it and retail is over £1000 ?. Not holding my breath that is does any better than everything I have tried.
Location does seem to play a part in antifouling effectivness

The cheepo Flag is no good on the River Blackwater. Flag themselves told our harbour master that, personally, when he complained. They say it needs to be the Performance . Having tried it he has reported to club members that that is much better. He also says that when he collected it from their factory ,in Burnham, they showed him a tin of both & there was a marked difference in weight between the two products.

Thanks, (sadly) the best comparative test I've ever come across.
 
What my test did not show was whether one type resisted growth for longer than another.. But on my own boat which i must have antifouled over 30 times , give it 8 weeks with new antifouling and a layer of slime occurs.
since 5 years ago i seem to be antifouling twice a year compared to only once per year previously. Guess the stuff is now so much weaker?

This is why I have coppercoat. It does not work very well but my boat is ashore in the winter. So it goes in at easter clean with very little work needed over the winter.
There is one problem & that is rust spots on the keel because I did not prime it properly & that is my fault. I have now re done it. A light sand where the lifting strops were & a clean round the waterline. Also I apply an erodable antifoul to the bottom 15 inches of keel where it settles in the mud in the marina & because I regularly damage the coppercoat coming in and out of the marina before there is enough water. That is not the fault of the coppercoat; but it only takes me a morning to sort.

Then mid season it comes out for a scrub so it is nice & clean for the second half. By then weed on the waterline can be 8 inches long . I also have to change prop anode mid season anyway. I average 1800 miles + sometimes years 2000+
Generally there seems to be less growth on the second part of the year. Boat comes out end October & gets washed ready for the following year

The cost of the mid season wash is part covered by the cost of the paint(2 cts), rollers sandpaper gloves etc & the original cost of coppercoat was £1070-00. The dearest wash so far has been Jersey at £ 180-00, cheapest Shotley & Inverness at £120-00.
When I last did it with Blakes Ocean performer the paint cost £ 96-00 plus accessories.
So bearing in mind I have no labour cost or do not have much work myself, I am better off.
