Simple to use,
proven results.
Hullguard forms an ultrasonic barrier around the hull of your boat that keeps algae and barnacles away. A unique, more efficient, transducer allows us to consistently achieve a greater range of up to 15m per unit. With one simple unit, all your algae & barnacle problems will go away.
Safe & Effective
Hullguard does not harm any fish or aquatic life. And unlike Zinc or copper coatings, no harmful substances are leaked into the ocean. Hullguard effects only the algae, the food source of barnacles. Without this food source, barnacles won’t attach to the boat.
Small & Compact
Hullguard has a diameter of 115mm (4.5in) and is only 80mm(3.15in.) tall. It is self-contained. There is no need for an external panel or control box.
Everything you need
in a small round disc
Automatic & Efficient
Hullguard automatically calibrates to environmental effects, such as the hull's effect on the output frequency of hullguard. There should be no need for maintenance beyond initial installation
Hullguard makes use of a more efficient transducer. This transducer guarantees more consistent results than any other product on the market.
