Bottom Paint Test Report: Panels Rated at the One- and Two-year Marks
Practical Sailor examines antifouling paints after yearlong and two-year in-water tests as 72 new paint panels are submerged for the next round of marine coatings tests
Looking for the best marine antifoulant to keep your hull clean? Check out Practical Sailor’s semi-annual bottom paint test report, which offers performance ratings on nearly 80 marine antifouling paints. Multiple sets of submerged fiberglass test panels—two in the Florida Keys and two in Long Island Sound—were pulled and examined for their resistance to hard growth and soft growth. Detailed charts show the results of the one-year and two-year tests for ablative paints, hard paints, and specialty paints (white paints, eco-friendly paints, bright paints, water-based paints, and racing boat paints). After the ratings were logged, testers retired the two-year panels to make room for the 2008 bottom paints. This lineup—72 paints in all—includes several low-copper paints and no-copper paints, which are becoming increasingly popular as sailors look for viable alternatives to metal-based paints. Paint manufacturers and distributors participating in the test include Blue Water Marine Paint; Donovan Marine; Epaint Co.; Flexdel Aquagard; Interlux Yacht Finishes; Kop-Coat; Pettit; New Nautical Coatings; Seahawk Paints; West Marine; and Boater’s World (Seabowld). Among the top-rated paints are Interlux Micron 66, Interlux Super Ablative, Pettit Ultima SR, Pettit Trinidad SR, Pettit Unepoxy Plus, Pettit Vivid, and Sea Hawk Biocop TF.
