Marine Maintenance: Bottom Paint Test Results

Find out how dozens of marine antifouling paints fared after one to three years of testing.

In the interest of saving readers both time and money, Practical Sailor recently inspected six different sets of antifouling test paints that had been submerged for varying amounts of time in the waters of Florida and New England. Each fiberglass panel set was painted with more than five-dozen different bottom paints, including ablative antifoulings, hard paints, freshwater paints, eco-friendly bottom paints, and copper-free paints.
