The Sound of Antifouling

This product has been around for a while, but you might have missed it. And that’s a shame because keeping the boat free of barnacles and growth is typically a high-maintenance job requiring yearly haul-outs and headaches. And all you need to prevent this is a sound.
“Barnaclean utilizes electronic resonators that emit low-frequency sonic waves to create a micro-thin layer of rapidly moving water over the hull, drive system or running gear. This movement makes it difficult for fouling organisms to attach themselves. To further protect, the low frequency mimics a predatory sound, creating a hostile environment for foulants.”
