How it Works

Ultrasonic Technology

The concept of ultrasonic technology for use in cleaning has been around for decades. Everything from jewelry to medical equipment has enjoyed the benefits of this innovative process.  Due to recent advancements in electronics this technology is now applicable to the process of maintaining a clean hull. The Barnacle Zapper works by emitting varied and pulsed ultrasonic frequencies from a digital control unit through a pair of transducers attached to the inside of the hull. The hull then acts like a tuning fork and transmits the sound waves through the water along the surface of the entire hull. The waves created disrupt the cell structures of the bio film and other micro-organisms causing them to die thus depriving algae and barnacles of their food source and leaving your hull free of any growth.

The Science of Fouling

Fouling begins with the attachment of bacteria. Bacteria is the oldest life form on the planet. It attaches to almost everything and when conditions are right proceeds to grow and multiply. It can appear as a slimy surface or can grow in a polymeric fashion to mimic hair or grass. It can be many different colors from blue green to brown or red.


The attachment of slime, algae, barnacles and zebra mussels are only some of the bothersome marine life  that can attach to the bottom of your boat. Collectively this phenomenon is referred to as fouling. Besides being unsightly, fouling growth can increase the roughness of the hull which decreases the vessel’s performance. It also affects the maneuverability by increasing drag, reducing speed and increasing fuel consumption. If left unattended, fouling can lead to corrosion of the hull and the ultimate deterioration of a vessel. In high growth areas such as Florida, it is common to hire divers to scrub the bottom of your boat every few weeks, even though you may have toxic antifouling paint on the bottom.

Growth Cycle

Once this slimy biofilm of bacteria is attached to the hull more advanced life forms may begin to attach themselves effectively creating a mini eco-habitat on the bottom of your boat. Eventually the food chain grows until the entire hull is covered in barnacles. Barnacle Growth Cycle

To prevent this, The Barnacle Zapper uses its ultrasonic technology to keep the initial growth away and the bottom of your boat clean! Even power washing and scrubbing does not keep your boat as clean as The Barnacle Zapper because of the ability of micro-organisms to form in the pores of the gelcoat.  No amount of pressure washing or cleaning can compare.
