Was very interested to read the " red hot chilli " addition to a / f. There is a canadian down here who has added strong weed killer to his and he swears by it.
Anybody tried that?
Following on from that if you mix both items into your a / f does that mean that I had better sell any stock I have in a / f maker's??
It would be nice not to lift the old girl out every year to check both her btms.

But if commercial stuff is still using tbt then what difference does a wee bit of paraquat make ?
Or am I being very iresponsible - enviormentaly that is ?
If I am then i guess its just back to the red hot chilli.

Paraquat and diquat are highly soluble in water, so would dissipate within a couple of days, and I suspect would result in the breaking up of the antifouling coat. Arsenic on the other hand...

I guess you are going to say that is not kosher either - so back to the red hot chillis!!

Met a retired Swedish gynocologist once. He had added tetracylin to his antifoul courtesy of the Swedish national health service. Reckoned it was necessary because the tree huggers there had even banned copper. Swore it worked really well.

And maybe it even improved the health of local passing fishes.

If you worked in the NHS there is no doubt lots of it lying around.!?

Re: Tbt

I seem to recall a PBO or YM article about 10 years ago that tested the usefulness of a chilli-based homebrew antifoul. It turned out to be useless. Is there any objective evidence for the usefulness of the new one? Otherwise I shall stick to BoatScrubber.

Re: Tbt

I tried a chilli homebrew A/F on the mooring buoy. About 100 grams of red-hot chilli in half-pint of mat emulsion paint. Useless! I only used it as the chilli was too strong for my taste and was going to fester away in the kitchen.

If it were possible to improve the efficiency of antifouling by adding something as simple as chili or weedkiller, don't you think International might have sussed that by now?

The secret of effective antifouling is applying it in the correct quantities.
 
A couple ( three maybe) years ago I decided i would try adding chilli powder. Compared with previous years I had very low levels of fouling, in particular very few barnacles that year or since.

Very effective you might deduce :)

Although whales do attract the odd growth - in the main, most marine organisms don't suffer unduly from fouling. So -why not simply copy nature's own solution to the problem ?

Coral is a very good example - it just sits there, year after year - and never needs lifting out for a scrub and re-paint. If you're wondering how coral 'gets away with it', take a look at it's exudate mucus: mostly palmitic and palmitoleic acids. Combine those ingredients into a marine coating (somehow) and you might even get yerself a Nobel prize.
 
I have a 1930s book that has a few lines on antifouling paint.They used arsenic and cianide and something else,can't remember what.So that's it, a bit of potassium cianide and Bob's your uncle,or was because he touched the stuff...
 
Quite a debate about illegal A/F, but which government department is responsible for inspecting bottoms (yachts that is) and how many skippers were fined last year. Lets face it it's a law so someone must be checking it, if only to collect the tax, err I mean fines. Hanging around shipyards, as I have been known to do, the odd 20 litre drum has found it's way onto the bottom of my boat. So who tests?
 
Hi all.

My tuppence worth.

I recently purchased a 19ft Calypso which had been "treated" with curry powder (not to mention the fish!). Seems like the barnacles and weed in Exmouth are partial to a bit of curry! The weed was nearly a foot long, and the barnacles were 1 inch thick! I think that would say that adding curry powder to ordinary paint doesn't work!

There is/was an American 'antifouling booster' product that contained exactly that - I saw it on sale in a certain South Coast chandlers a couple of years ago, had to point out to them that it was illegal in the UK (prescription drug; plus uncontrolled use of antibiotics is not to be encouraged as it can lead to increased resistance in pathogens, eventually rendering the drug useless when it's really needed).
