Cruising America's Great Loop and other inland routes
View all threadsdoes anyone know the formula, or additive, or ingredients, to make the old
school bottom paint , you remember, the one that actually worked? That
being the same one the armed forces still can use, and all commercial ships can
use, and all tugs, but we can't!
See you in Paradise!

It was some sort of a tin compound that did the work.
For some reason "tri-butyl tin" pops into my head. I
seriously doubt that you could find it today, though.

As I recall you can still get that paint in the Bahamas. You might have to have it applied by the yard but in Abaco it was still used last winter and someone posted on one of the lists about it. (if my memory serves me right) Elaine

Capt Sterling:
I relayed your querie to a good friend of mine who seems to know all
things. Here is his reply (name removed to protect the
innocent). It supports what Jim, Larry and others have said:
The magic "stuff" you seek is known as TBT - shorthand for Tri Butyl
Tin, or tributylin. IT was a very effective bottom paint additive,
banned some years ago. Theoretically it had been shown to cause
destructive results, especially on filter feeding sea life - like
oysters, crabs, etc. I had it on my boats for years, and could never
understand how the coon oysters thrived in great profusion on the
pilings just inches from the boat.
Anyway, in the Bahamas I think it is still available. The last I had,
I bought at Sherwin Williams, since it was still legal to add it to
your house paint, to keep the mold and mildew from growing on the
north side of your house. When I added it to the Trinidad bottom
paint, I got nearly 3 years life. I just wanted to make sure it
worked before painting the house. I don't recall that it was terribly
expensive. A dozen little bottles was $50 or so. Not sure if it can
still be purchased.

Capt. Sterling and List,
The additive was "tri-butyl tin" which can no longer be used, also copper bottom paints. Modern ships and the Navy use a new microbiocide called SeaNine which was manufactured by Rohm and Haas Company, Philadelphia, PA. The company was sold to Dow Chemical Co., Midland, MI. SeaNine based paints require special training and a space suit to apply but lasts up to 5 years or more in salt water.
