Seabreeze Restoration part 3: Bottom Paint

One issue that I am struggling to find an environmentally friendly solution to, is bottom paint. If you leave your boat in the water, you have to deal with the massive numbers of organisms (such as barnacles) that will try to attach themselves to the side of the hull. This is a problem because they add significant weight and friction to the hull. Which makes the boat move slower and use more fuel. Traditional bottom paint slowly leaches toxins into the water, that repel these organisms. However, recent studies are linking some serious environmental effects to the use of these paints. I haven't come up with a solution to for this yet, but I am doing a research project to test several alternative bottom coatings, to see what I can find out.
