Ultrasonic Antifouling Test Update
Disappointing results put SmartAntifouling field test on hold.
In April 2012, we launched a long-term test of SmartAntifoulings M20, an electronic antifouling solution that the maker claims uses ultrasonic waves to prevent algae and barnacle growth on boat hulls. The M20 transducer emits a high-frequency vibration that creates a thin layer of moving water around the hull, making it difficult for organisms to attach to the hull. The evaluation was set to run for a few seasons. However, after just three months of testing, disappointing results prompted testers to put the experiment on hold until the test boats bottom is re-painted later this year.
