I know it's a matter of degrees and in the past I've used the most copper laden paint I could (Pettit Trinidad). I've been out of sailing (and owning) almost ten years but the illness is latent and renewing itself. Poison is poison (one guy on another site stated that a little biocide would be good for the Upper Chesapeake) and eventually we must find another way. Not holier than thou, still drive a body on frame SUV but I wonder if such enforced changes a bit at a time in terms of the larger population are not a bad thing? It's going to be interesting owning another sailboat in "these times".
