Ultrasonic Cleanahull


Ultrasonic Antifouling Systems, Australian-made by CleanAHull™ are ideal for the protection of your hull from marine fouling and can drastically improve your vessel performance and save money. With a clean hull your vessel will maintain performance and manoeuvrability while being more economical with improved fuel efficiency and reduced passage times. When a hull or running gear is fouled, it can take 30%+ more fuel to push through the water while also taking longer to arrive!

The CleanAHull™ ultrasonic transducers are installed in strategic locations throughout the inside of your boat’s hull to provide the best transference of ultrasonic energy into the hull. This energy is then dissipated out into the water close to the hull at a 180° arc providing bio fouling protection. Ultrasonic transference is best through solid objects that the transducers are directly attached to, and there will be some attenuation (loss of signal) when ultrasound attempts to transfer to acoustically isolated items (stern drives, IPS drives, shafts, rudders, etc). CleanAHull™ ultrasonic transducers can be installed directly onto isolated items such as rudders (tiller/ shaft), IPS drives, stern drives (transom shield), thrusters, etc for ultimate targeted protection of these devices.

The main factor in determining the correct system and number of transducers required for protection is the hull waterline length (LWL). As the vessel hull size increases so too does the surface area in contact with the water and in turn the area requiring ultrasonic protection. During installation there is no through-hull drilling required. Our systems can be installed without removing the vessel from the water.


The advanced ultrasonic antifouling system destroys algae and prevents barnacle growth using advanced specifically-tuned ultrasonic frequencies. These blasts of high frequency ultrasonics prevent barnacles and algae from growing in the first place. By keeping your hull cleaner for longer you are able to extend the intervals between re-antifouling of your vessels hull by up to 3 times.


Ultrasonic antifouling has been used in industry for many years and has only, in the last decade, been adapted for use with marine vessels. The digital transducer control module sends a refined program of short ultrasonic wave burst signals to the ultrasonic transducers mounted onto your hull, generating acoustic sonication that is inaudible to humans. The ultrasonic sound waves emitted through your hull generate a barrier at a microscopic level of moving water molecules throughout the submerged hull, which destroys algae and prevents barnacles.


The system is designed to operate on as little power as necessary to provide ultimate protection. A special highly-efficient digital control system generates a specific range of frequencies, and by controlling the longevity (duty cycle) of the bursts and refining them through automatic calibration we can maximise the 50W peaks while keeping the actual average current drain down to as low as 200mAH at 12VDC(2.4W) per transducer.
