Antifouling for big boys............

We were in the Caribbean this time last year, and saw TBT antifouling in the local swindleries. And on top of the basic toxic stuff, if you want to keep your boat in a seriously weedy environment, you can buy extra Tri Butyl Tin powder to up the potency of your antifouling even more. HWMBO was well impressed. Wanted to buy some to bring home.

To be fair, it is very potent, and because our boats spend more time stationary than moving, the concentrations immediately local to out moorings can get very high. Sufficient to knock out shell fish, and corals in the Caribbean.
 
Re: Since I actually buy antifouling for big boys, may I offer some FACTS?

You have a nice expensive docking coming up as the yard quote Marpol at you and make sure the blasting residues are "environmentally disposed of"!

Painting over it has been popular with ship managers; less popular with owners paying the fuel bills...
