Mr Hermens and Mr Camp respective owners of the sailing yachts "Absaluut" and "Twirre" both fitted Ultrasonic antifouling units to their boats in March 2006 before launching into the water at their home base of Maasbormmel in Holland. It soon became clear to both of them that the ultrasonic system is an excellent alternative for antifouling. They both contend without any reservations that they are very satisfied with the result. The hulls of both yachts remain totally free of growth. "The purchase of the Ultrasonic antifouling system appears without doubt to be a good investment". |
