Your quote is years out of date and in fact was irrelevant by 2012, when the IMO ban on TBT anti fouling paints was ratified and subsequently enforced in the United States

It’s a 2021 citation.

For the nerds on here…. Silicon, Germanium tin and lead are all part of the carbon family and can be incorporated into biological processes in similar manners… but small perturbations in size and reactivity mutate the proteins and f-things up

That is reagent grade… tbt is used in organic synthesis to add a butyl group to a nucleophile. And at a concentration of 1 ppm

 

[cousineddy]

Uhhhh. Would it work if you mixed it in with an ablative paint?

So we should use bottom paints that are highly toxic to aquatic life to keep our sailboat bottoms clean so we can win races and put people, like @fstbttms out of work? If aquatic life could weigh in, I'm not sure they would be real supportive of using TBT or other high toxic chemicals for this purpose.

That would make your boat cost millions

$45 / month for a tall ship, Joe? That’s awesome!

Are you referring to my icon the first-rate ship or the line "HMS VICTORY"? It is a the most famous vessel in British Naval history and can be toured where it rests in Portsmouth. UK. They didn't use divers back in the 18th century. The ship had to be dry docked and its bottom sheathed with copper sheets to help protect its bottom from torqueedo worms. Smaller ships could be careened.

However, my Catalina 27 is serviced monthly by my very excellent diver CHP Diving. Yes, that's a plug... highly recommended. He just had to raise the fee from 40 to 45 bucks. $1.66/ft.

 

[Joe]

OK, if you say so.

What's your deal? Not one positive or helpful comment... just snarky criticism. Really uncool, my brother. Chill out.

I’ve gone back and forth with capta many times over the years about anti fouling paint efficacy. His unvarying position is that it doesn’t work. Mine is that he has unrealistic expectations. Now he tell us that 30 years ago, it did work. Well, having been in the business 30 years ago (OK, 28 years ago), I’m here to tell you (and him) that there is not a whole lot of difference between how effective bottom paints were then and now and I have the real world, professional experience to back that up. Capta does not. I didn’t feel compelled to explain that to you and everybody else again yesterday, but since my “snark” apparently got your panties in a bunch- well, here we are.

BTW- speaking of professional hull cleaners, you should know that you are paying what is generally the lowest rate in the country. A $1.66/foot? Seriously? We were charging more than that 20 years ago, here in the Bay Area. I don’t know how your diver (or any diver in SoCal) makes a living. Unbelievable.

Are you saying we should put the interest of slime ahead of our $100k racing boat’s performance? Preposterous.

Are you under the impression that the biocides in anti fouling paints only effect the "slime" found on boat bottoms?

 

[cousineddy]

Yes

 

[fstbttms]

Yes

Well, you would be wrong.

 

[dlochner]

Are you under the impression that the biocides in anti fouling paints only effect the "slime" found on boat bottoms?

Yes

That would be an incorrect assumption. The biocides leach out of the paint and are ingested by a multitude of organism in the water and humans and other animals if the water is a drinking source which many freshwater lakes are.

That is why I don't eat les huître

Only if they are fried!

Why is that not common anymore? Seems like a modern version would be to encapsulate copper "dust" in an epoxy like paint ....that should last a good long while. We use copper oxides now but it is unclear to me why. Copper metal would oxidize naturally in a marine environment.
