The bottom paint update coming up in the March issue of Practical Sailor will feature more than a dozen new antifouling paints, and many of them are no-copper or low-copper varieties. While paint manufacturers could potentially save a bundle by reducing the copper content in their paints, the costs associated with bringing an effective alternative biocide to the market are a big impediment. (No, simply adding cayenne to a cheap bottom paint doesn't work.) If there is to be any motion in a green-paint direction, government policy will be the prime mover.
