About Hull Shield

Ultrasonic Antifouling - How it Started

Discover the journey of Hull Shield – from problem to solution. Hull Shield ultrasonic antifouling products were developed to help boat owners just like you.

How Ultrasonic AntiFouling Works

Hull Shield products protect vessels against the effects of marine biofouling. Our ultrasonic systems use of ultrasound to limit and restrict the ability of microorganisms to attach to surfaces that are exposed to raw seawater. Ultrasound wave energy is transmitted through these surfaces to create an ultra-thin layer of high pressure between the protected surface and the surrounding water. The resulting area of high-pressure is a barrier which microorganisms cannot pass through.
In simpler terms, each pulse of ultrasound induces a small vibration in the surface material. These micro-vibration repel fouling organisms away from the material, keeping it cleaner for longer.
