Ultrasonic Antifouling or biofouling prevention is not a new process and in the past analogue versions of this system have been available for the marine industry. Our system is very different from this, utilizing a specifically designed program placed on a Micro Controller Integrated Circuit we control the frequencies closely and operate in a range that analogue systems cannot. because of this much better control over output and frequency we can also reduce the required level of power output.
Key Points of difference.
- Less power consumption and lower output power
- specifically programmed advanced frequency range to offer the best protection from more strains of algae.
- higher quality frequency output range allowing a much greater frequency range and control over frequency and time in operation of each frequency.
No. The Ultrasonic System operates in such a way that it damages the cells of only very very small organisms such as those that make up algae, it has no effect in this low power output version to any fish, marine mammals, pets or humans.
Our system is developed to keep your hull clean from barnacle and algae growth. It won’t however prevent the natural staining cause by the water in your area. We suggest that an antifoul coating every three to four years would be a good idea to keep your hull staining mostly non visible, to enhance your vessels appearance and help prevent corrosion / water ingress in the case of metallic hulls. This lift for antifouling is also a great opportunity to replace anodes and inspect the hull for other issues.
It is expected that a small amount of growth will occur close to the waterline around the vessel where the hull is exposed to both air and water. Our system only operates effectively within the water as it is more dense and concentrates the Ultrasonic Waves to the area close to the submerged hull and fittings. This growth is generally not complete and will usually come off when under way or will easily come away with a deck brush / light scrub.
CleanABoat.com also produces quality Marine Products including a specialised hull cleaner designed to remove yellowing mineral / scum stains.
No. The system operates much like any other electrical component onboard and will not interfere with any others. The only systems similar on a vessel are the depth sounders and fish finders however they operate in a higher frequency, at about 200kHz and will not interfere with the lower end of the Ultrasonic range where our system operates.
No. Ultrasonic Antifouling only produces Ultrasonic sound waves and no electrical current, so there is no increase in your anode degradation/wear.
As our Ultrasonic Antifouling system will keep your Hull clean from growth it will reduce the drag caused from this biofouling and improve economy and performance, reducing fuel consumption. Ensuring you get the best performance throughout your usage season.
By improving performance and reducing resistance by keeping the hull clean you will save substantial amounts in this reduced fuel consumption and an extended range.
This depends on many factors. If the vessel has a clean hull then your results will be noticing no growth. However if your system is heavily fouled with algae and barnacles, the algae and barnacles will begin to die off within a few days of use however the algae will only begin to actually fall off when the boat is underway, a regularly used boat will generally clean its hull off within a few weeks. Remembering that the hard bond pre-existing barnacles can exist beyond their death and they can then remain until the are scrubbed or scraped from the hull. It is generally advised, to achieve best results, if the hull is heavily fouled it should be scraped / scrubbed at the time of the Ultrasonic Installation.
CleanABoat.com manufactures and closely watches the quality control of our own systems, and as such produce a product that utilizes only the best available components. The Module itself is manufactured on laminate protected Circuit boards and enclosed inside a dust and splash/hose proof enclosure to keep out unwanted moisture, the transducers are encapsulated / potted inside a fibre reinforced plastic mounting using the highest quality electro-isolation available. While we warrant our systems for 2 years we fully expect that provided the installation is performed correctly the system should see effective operation for many many years. The only consideration to reduce this life expectancy would be the chaffing of cables or poor installation.
Yes. Our system has inbuilt error checking circuits to provide audible and visual warnings if the fuse that operates the Transducer should blow. If the internal fuse (2 Fuses, Transducers 1 and 2 connected to FUSE 1 and Transducers 3 and 4 connected to FUSE 2) should blow the unit will give an audible beep, an error light on the facia and the LCD will give clear text error status and tell you which Fuse has blown. This warning will go out when the fuse is replaced. ensure you turn the module off before replacing the fuse and back on once replaced.
The short answer is No.
We do however recommend periodically checking cables and connectors to ensure there is no damage or chafing. We also recommend from time to time you check the transducers operation by listening closely to each transducer for the faint clicking sound and inspecting the lcd information on the control module itself. We also recommend checking the transducer is tightly secured to the hull.
The CleanAHull.com Advanced Ultrasonic Antifouling system is fitted with enhanced features unlike any other available. Each individual channel has an individual fuse for protection. Multipl internal temperature sensors and an advanced monitoring algorithm. Should there be any issues an alarm will sound and the error state will be displayed on the LCD panel.
No. The short answer to this is no, the system operates in a frequency band much higher than what the human ear can hear. You will however be able to hear a slight clicking sound when within close proximity to the Ultrasonic Transducer and a quieter clicking when very close to the Power Control Module itself, this generally is only within less than 1m of the transducer and some people report only being able to hear it when almost on the transducer itself.
Yes, we recommend that Antifouling protection should be applied to your vessel’s hull and also running gear. Our Advanced Ultrasonic Antifouling system will drastically improve the longevity of your existing antifoul coating. It will also drastically increase the time frame between haul outs for re antifouling.
The CleanAHull.com Advanced Ultrasonic Antifouling system will, unlike other coatings, provide enhanced protection for shafts, props and other running gear from growth. This protection won’t however be as effective as the hull due to the nature of the running gears connection to the hull via isolating bearings, hinges and other fittings which dampen the resonance of the Ultrasonic waves. Generally correct Transducer Positioning can enhance the performance and protection to these devices. CleanABoat.com is also currently in prototype testing stages of a specialized upgrade to our Ultrasonic Antifouling system that will provide additional protection to stern, leg drives, propshafts, props and rudders. Contact us for more information on this and we expect retail sales to commence mid 2011.

Yes, the system is transferrable easily to a different vessel. With the exception of the mounting ring, as a very strong bonding resin is used it is unlikely you will be able to remove this mounting ring. We can provide new mounting rings upon request so there is no need to attempt to remove this mounting ring. The rest of the system can easily be transferred to the new vessel.
As the transducers are fitted to the inside of the hull, there is no requirement to lift the boat for the install itself (see below for one exception to this). If however your vessel is fouled prior to the install we generally recommend lifting the hull to at least remove the existing fouling with a pressure wash or scrape. The Ultrasonic Antifouling system will destroy algae and barnacles on your hull and the majority of this growth will come off during use the barnacle shells that existed prior to the installation of the ultrasonic unit will die but not fall off without physical intervention through a scrub/scrape/water blast during a lift or by hiring a diver to clean your hull.
There is however one exception to this rule. If your vessels hull is Foam or Balsa cored it is recommended that you remove the vessel from the water to carry out the installation to prevent any unwanted mishaps.
Our CleanAHull.com Transducers are fitted on the inside of the hull using a special mounting footprint that is bonded to the specially prepared surface. There is no drilling or cutting required.
The best positioning of the transducer(s) depends on the system you have chosen. One transducer should be positioned close to the propeller and shaft to offer maximum protection, usually 2/3rd’s of the way back from the shaft exit point from the hull. The other transducers should be positioned approximately every 10 – 12metres along the length of the hull.
When the vessel is longer than approx. 24m sometimes the beam of the vessel becomes too wide for a single transducer across the width, in this case two transducers can be positioned across the width of the vessel.
The Ultrasonic Transducers are to be fitted to the hull away from any large hull structures, stringers or bulkheads. Each transducer should be approx.. 200-300mm off the centreline of the hull. On a vessel with Stern Drives positioning of the transducer should be between 100-200mm forward from the transom. In each vessel the built in structures may prevent you from sticking to the recommended installation configuration and in most situations this is ok to use these as a guideline.
Generally this will depend on the size of the boat and the system you choose. The general system installation requires mounting a special ring to the hull for each transducer to be installed using the provided bonding resin, mounting of the control box(es) near the Transducer mounting rings and running some cables. In a setup with more than one system a simple link cable is run from one transducer control module to the next via the pre-existing wire runs throughout the boat. Generally it will take approx. 3 hours total time to install our system. It is a requirement however that the transducer mounting rings are allowed approximately 24 hours to fully cure before the transducers are mounted.
We will provide all required installation documentation and required items for installation. The process of installing our system is very simple and we have adopted a simple plug and play setup that does not require much in the way of wiring.
Things to Consider with your Hull
Things to Consider with your Hull
Yes. CleanAHull.com Advanced Antifouling system will work on a balsa cored hull construction provided you remove a small section of the balsa core to expose the outer layer of the hull. As the Ultrasonic Antifouling system needs to be connected directly to the outer skin of the hull for it to be effective. You can carefully cut a section of the inner layer and trim out the balsa core, then re fibreglass the section to seal the balsa core layer and re enforce the outer hull layer. You can then proceed to prepare and mount the transducer on this outer hull layer as per normal instructions.
Please contact us if you have any concerns or would like some support.
Yes. Our system is designed to work on aluminium hulls.
Our system is effective on hull thicknesses from 10mm and up to 70mm outer thickness. In some situations additional Transducers may be used to improve performance on thicker hulls.
Please contact us if you have any questions about your hull configuration.

Unfortunately due to the density of wooden hulls Ultrasonic Antifouling will not be effective. Ultrasonic Anti foulgin requires a very solid mono formed (without joins like wooden planks) substrate in order to resonate the Ultrasonic waves throughought. The relatively low density of Wood prevents this and the Ultrasonic waves tend to only carry around a very small area nearest the Transducer.
Ultrasonic Antifouling lends itself best to steel, aluminium and GRP/GFRP (Glass Reinforced Plastic, Glass-Fibre Reinforced Plastic).
Yes. Our system is designed to operate on 12VDC or 24VDC and will effectively work while-ever it is provided a good 12 or 24VDC supply.
We are currently working on Solar and Wind Charging systems that will enable a renewable energy source to enhance usability of our system on swing moorings when shore power/battery charging is unavailable.
CleanAHull.com has a very efficient power circuit and transducer design to maximize output for minimal power consumption. Our low power consumption operates with a consistent average drain of approx. 220-250mA @ 12VDC per Ultrasonic Transducer.
We generally recommend for best results that the system is enabled 24 hours a day. We have provided an on/off button on the front of the unit so that it can be turned on and off if required. If for whatever reason you would prefer the system only runs for part of the day, we would sugest the daylight hours and using a timer to turn it off at night, for best results it is advised to leave the unit on indefinitely.
