This approach suggests 3 things

First, you have not got a clue what you are talking about

2 You believe in fairies

and

3 You have time on your hands and are desperate to find alternate ways of wasting it.

Or
4 that you, me and several other have fallen for a wind -up

Why don't you try DIY shed own brand white matt emulsion with marmite & chilli powder? Should be just what you are looking for :encouragement:
When you patent it & make millions, don't forget to bung me a few quid!

As SimbaDog says, use emulsion paint with magic ingredients, but don't forget to thin it with petrol - it'll make it quicker to dry, and to speed things up still further, just flick a match at it - you won't be troubled by barnacles after that.

Why are people so aggressive and nasty?

On both 'sides'.

Someone posted in a response to me, that this is a community. Not my definition of a community. Or perhaps it is in a similar sense of community to Lord of the Flies.

Some excellent posts on the history of antifoul that contained info I did not know.

I previously posted about some ultrasonic device that either reduced or eliminated the need to antifoul. I have no idea if it worked or not, but I do remember people coming together to test it and see if it worked - a good project in the spirit of PBO. I guess it did not, as not heard it revolutionising antifouling.

I am a contributor to several forums. Motorbikes for example where I see no such vitriol. So why in sailing? Perhaps because of an older curmudgeonly membership? I don't know.

Flame away!

I agree with you there have been some interesting contributions & personally I find nattering about boats interesting.It just seems to me that some of these self proclaimed experts cannot face their opinions being challenged.Maybe their knowledge is not as great as they think it is!
All a bit sad really.

Does that include people who think they know better than antifouling manufacturers?

This includes people who think spending lots of money may be suitable for some people but not everyone.
But wasting money on initiatives doomed to certain failure - or a heavy fine - is OK?

Basically, if it doesn't work, you've wasted your money. This is the most likely outcome; people have been attempting to stop fouling on boats for centuries without much success until copper started being used in the late 18th century. Anything you'd be likely to lay your hands on has almost certainly already been tried. Even quite nasty stuff like oxides of lead don't work. There are plenty of urban legends about things like chilli powder and weed-killer, but that's all they are - urban legends, with no comparative tests to bear them out. There are excellent biological reasons why most of them are non-starters.

If it does work, it will almost certainly be in violation of strict rules concerning the release of biocides into the environment. You have published your intention on a public forum; I don't think you'd stand a chance of defending yourself if it came to court. Frankly, given that those rules came into being precisely because people were noticing that valuable marine resources were being damaged by the uncontrolled release of biocides into the environment, you'd deserve any fine you were hit with. The most effective substance of all - TBT - was banned world-wide for exactly that reason, despite commercial interest in it being retained. You mention farm runoff - that is also controlled, and a farmer who caused significant pollution of waterways by weed-killer, pesticides or anything else would have the book thrown at him good and hard. I live in an agricultural area, and can assure you that it happens; slurry is the usual one hereabouts.

For good and sufficient reason, the manufacture of anti-fouling substances requires a license. To get a license requires that you demonstrate that the formulation you're using meets stringent conditions. Antifouling manufacturers meet those regulations; I doubt you could.

I really don't get your problem with the cost. I can do my 31' boat with 2.5 litres of whatever the chandlers are selling cheap for about £50; that's two coats and it usually lasts two years (fouling is light where I am). Almost anything else that you put together that stands the slightest chance of working will probably cost you more. Time - my wife and I can put on two coats of antifouling in a couple of hours; I don't see that anything else would be significantly quicker. And antifouling is usually designed to go back in the water soon after coating; many people do it between tides!

Right royally I'd say.... but for such an independently minded sport (or so I would assume) I'm kind of interested in the number of nay sayers in the thread - if it doesn't work it harms no one but the OP, so why is everyone so keen to save him from himself?? It's a bit like the outboard well in the Centaur thread all over again.... :cool:

Or the barnacled egg..............

Now that would be painful... :D

What (mildly) intrigues me are the claims here and elsewhere for the efficiacy of chilli, when dulcibella (#37) points out that most fouling organisms lacks capsaicin receptors. (They are found in some fungi and in mammals - hence the trial of pepper plants as 'hedges' for crops in elephant conservation.) Is it that chilli contains other substances to which fouling organisms are susceptible, or that its proponents are mistaken? I have never seen anyone cite a controlled trial, so must suspect the latter.

I think the point is that he is quite likely to harm himself, the environment and his wallet.

There was a long discussion a couple of years ago about the ultrasonic antifoul system, but I can't remember what the outcome was, so it might be worth the op digging that one up for a read. I suspect it wasn't all that effective or it would have gained wider acceptance by now. The undeniable fact remains that, despite a lot of effort by a lot of people, conventional antifouling paints are the best we've got, and I'm the first to admit they aren't brilliant.

If you want to prevent fouling as cheaply as possible, i can recommend boat jumbles - that's where I get my antifouling from and have done for the last twenty years. Dented tins, old stock etc, all for around £20 for a 2.5 litre can.

I am happy to learn from other peoples experiences & have trawled to find out what these are.Personally I can't see why you should feel threatened by this.:ambivalence:

What makes you think I feel threatened by your daft ideas - perhaps concern for YOUR lack of concern for the environment, but more by why you think you can achieve something that nobody else has achieved and is fundamentally unachievable in the way you propose.

Current products are arguably less than satisfactory, and if you bothered to read what people have written you will understand why. As with many products there is an increasing degree of effectiveness, broadly related to price and effort. So you can do nothing and have a fouled bottom very quickly. Pay a little bit of money and spend a bit of time and delay the fouling, pay a bit more money and put in a bit more effort to delay it for longer, or you can take a long term view, put in a lot of effort and pay a lot more money to have a product which is effective for many years.

What you can't do is pay no money, put in no effort and get an effective antifoul, despite what you may think.

Can I respectfully suggest that you should channel your inventive entrepreneurial talents into something which would earn you fortunes (the antifoul one wont thats for sure) allowing you to carry on using a mainstream product.

There is a viable alternative to antifouling every year, it was suggested to you in the first post replying to your OP, 8 pages ago, your reaction was:

"Far too expensive & far too much of a polava."

I can assure you long term CopperCoat is far cheaper than antifoul. However if you want to reinvent the wheel, then please continue.
