Best ablative bottom paint for the tropics….

[SV Windrush II]

Sounds like discussing TIN based TBT paints is pretty much a waste, one only needs to do a simple search to find out it is not only banned but is so toxic that I can't imagine anyone wanting to use it.

I did find Ameron ABC 3 localy here in Auburn Washington at my local PPG store for 89.50 pr gal. which I thought is a great deal.

If you are looking for justification to use an illegal paint, I'm sure you'll find some whether or not we waste any more time and electrons trying to convince you otherwise.

Well I have to confess I do have a legal background and my first thought on reading your post was:

"Objection, assuming facts not in evidence."

Since an order of magnitude is 10 and you claim tin based paints are "orders of magnitude more effective" by implication you are saying tin based paints are hundreds or thousands of times more effective than copper based paints. If I thought that was true I might consider using a tin based paint since my current ablative bottom paint will be two years old in May and I will be repainting it then. But I doubt even a tin based paint would last two hundred years, less yet two thousand years.

I also have a hard science background since I was involved in environmental law and even a freshman chemistry student would not try and extrapolate based on your claim.

But my real objection is your accusation that I am trying to justify using a tin based paint on my boat. I am a serious diver who spends lots of time in the water close to my boat and would have real concerns using a tin based paint. I normally find a nice shallow sandbar every month or so and knock the growth off my boat. But before I do this I put on a hood, full wet suit, booties, and full face mask. Even with the traditional ablative paint I use I worry about what I see when I do this. I am sure you have seen much worse since you have more experience than I do knocking growth of boats with a huge range of bottom paints.

My goal is not to justify the use of tin based paint. I am simply trying to find out if and/or how much worse it is than conventional bottom paints.

OK Gang…..

At this point I have to apologize for the Original Post. I did not mean for it to digress to a tin slinging contest.

I was just trying to get up to speed on Ablatives for warm water….

Sorry…...

Regardless, as has been mentioned, TBT is banned, internationally. Given that, I personally don't want to bother with any comparison, for I don't care to break the law. Nor do I want to compromise my personal morality.

I take this to mean you have no evidence to back up your claim that you posted links I requested.

Good point. I would also be interested in that. I have used Micron in the past but not sure if it is the best or not.

Well, I can't believe I did his work for him, but here is the International Maritime Organization's case against tBt anti fouling paint. I feel confident that tomfl will find fault with it.

"The best"? The best being the longest lasting? Oh, you mean the best as in the cheapest? Wait, you mean the best in terms of environmental health and safety of course!


"Well I have to confess I do have a legal background and my first thought on reading your post was:" ...legal background - Jailhouse Attorney?

"I take this to mean you have no evidence to back up your claim that you posted links I requested."I for one would be happy to comply w/ your request. Anything else your Majesty?

Thanks in advance.

You guys are too funny, at least I got some good info and a laugh

Wooden sailing ships were sometimes clad with copper sheet below the water line. I have seen self adhesive copper foil advertised on craft web sites. I wonder if one could use that in lieu of bottom paint? Say, apply the foil from keel up, stern to bow. Just wondering.

That would be copper pollution.

Can't even imagine what it would do to the prop/shaft...?????

It would peel like an onion.

Now all I ask ? Is you stop and think about it, before you pose a question. : devil:

That's funny because the first time we bought it we paid $125 a gallon. Recently we paid a little over $90 a gallon. We purchased from a commercial supplier which may have kept the price down!
