Practical Sailor’s 2007 Bottom Paint Field Test Update
In addition to our annual bottom paint panel test, we have applied leading anti-foulant coatings to several of our test boats. See how they have fared.
For the last year, Practical Sailor has been conducting head-to-head antifouling field tests on four boats (two sail, two power). In August 2005, we painted one of our test power boats—a 21-foot Parker—with three coats each of two products: Interlux’s Tarr & Wonson Copper Boat, a soft paint, or sloughing “workboat” paint, that is one of the cheapest on the market, and Interlux’s Micron 66, an advanced (and expensive), ablative copolymer paint blended to release biocide at a controlled rate. So far, Tarr & Wonson’s field testing and panel results indicate that a budget paint will hold out well for at least one season without hard growth, although you may have to scrub the bottom once or twice. At one-third the price of Micron 66, the Tarr & Wonson paint is not as effective, nor do we expect it to be.
