Hull Shield ultrasonic anti-fouling products have been working to keep boats clean for years. No matter the port or destination, Hull Shield systems have been deployed worldwide with great success. You can read about some of our recent projects and case studies below. We conduct field tests on various hull types and materials as an ongoing effort to measure (in situ), the performance of our ultrasonic anti-fouling products. Test results are used to ensure, and improve, the effectiveness of the technology and product line.
