Boat hull paints and threats to water quality
Boats that are kept in the water have always required maintenance effort to remove species such as barnacles, oysters, mussels, shipworms, or algae that become strongly attached to boat hulls. These so-called “fouling” organisms cause drag that can significantly slow the vessel, alter maneuverability, and damage the hull. Copper has been a standard ingredient in hull paints for many decades, but it has only been in the last ten years that water quality sampling has shown that the paint, in some cases, can cause exceedances of water quality standards.
Antifouling coatings work by slow release of a toxic chemical (biocide) from the hull coating,Read More
