Install a Sonihull Go System and start saving money on re-application of antifouling paint, reducing shipyard visits, intensive cleaning regimes, drag and fuel consumption.
Ultrasonic Antifouling Systems
Now the new SONIHULL GO
Alfa Laval Sonihull GO is a simple and effective biofouling management solution built with ultrasonic anti-fouling technology that prevents the use of biocides, cleaning chemicals and toxic antifouling paints.
Traditional anti-fouling systems, such as surface paints, rely on the release of toxic chemicals and microplastics into the ocean. SONIHULL is based on the physics of ultrasound to keep marine fouling away from your vessel. You can protect your hull or you can choose to protect keels, rudders, IPS drives, outboard motors, water jets, propellers, keel coolers, saltwater pipes, and cooling water inlets. From small boats to complex super yachts.
SONIHULL has got you covered! No need for a boat lift or floating dock. The system can be installed in the water!
Benefits:
Sonihull works on Steel, Stainless Steel, Titanium, Fiber Glass, Carbon Fiber and Rigid Plastics.
It does not work on wooden hulls, and in combination with silicone-based anti-fouling paints to protect auxiliary systems, we recommend thin layers of propspeed because when it is applied too thick, the ultrasonic wave loses resonance, limiting its effectiveness!
- Without cleaning hard-to-reach areas, extended maintenance intervals, less downtime, and reduced operating costs.
- It can extend the life of your paint, no more scraping, just gently clean your hull or pressure wash and reduce your dive inspection by up to 25% (every 3-4 months).
- The system is transferable from boat to boat.
- Inaudible for humans and marine life without interference with sonar and electronic equipment.
- Lower fuel consumption: clean hull, propellers, and rudders can reduce fuel consumption by up to 30%.
- It can save up to 95% of capital and MRO costs compared to impressed current antifouling systems.
- Compatible with RS232/RS422 communication interface and Modbus for remote control with critical path fault monitoring.


Pragati Yacht has specialized in ultrasonic systems installations with over 8 years of experience. Contact us to request our installation services!
We have installed Ultrasonic Anti-Fouling Systems on the following brands:
































About the system:
- It can be installed in the water, without the need to haul the boat out.
- Each transducer covers 32' circumference. Each one uses 0.3 Amp, can use 110, 220 VAC as primary or 12-24 VDC as secondary or either one.
- The box is smart, so it will automatically select the available power source.
- High-quality components that will provide you with years of service with maximum performance.
- The system is transferable from boat to boat.
- This system works on steel, aluminum, stainless steel, titanium, fiberglass, and rigid plastics.
- Silicone - based coatings are known to dampen up to 40% - 50% of ultrasonic signals and will reduce system effectiveness
How does it work?
Once the transducers are installed, they will start emitting ultrasonic waves, creating non-inertial cavitation at a microscopic level that will resonate throughout the outer layer of your hull, preventing barnacles from attaching to it. These ultrasonic waves are not audible to human, fish and marine mammals.
By increasing and decreasing pressure, Sonihull prevents barnacles from adhering to the hull.
The Sonihull GO ultrasonic transducers are attached to the dry side of the surface being protected. The transducers produce a microscopic pattern of increasing and decreasing pressure in the layer of water touching the protected surface.

Microscopic bubbles are created as the pressure decreases and implode as the pressure increases.
Boats and Yachts
Start saving money on hull maintenance fees by reducing drag and fuel consumption.
Imagine freeing yourself from the yearly ritual of sanding, scraping, and repainting—all while maintaining peak vessel performance and reducing environmental impact with the right system configuration.
Protect your hull, rudders, IPS drives, sterndrives, and thrusters.



















Mega and Super Yachts
No cleaning. No chemicals. Reduced technical workloads.
As yachts increase in size, their systems become more complex. They require larger engines and gensets, higher-capacity cooling systems, and intricate pipework to ensure everything remains cool and efficient.
With Sonihull ECO ultrasonic antifouling systems, superyachts no longer have to rely on costly overhauls, intensive cleaning regimes, or chemical dosing systems to keep pipework free from fouling.
You can protect:
Inside: Waterjets, Pipework, Cooling Systems, Fuel & Water Tanks
Outside: Hulls, Propellers, Keel Coolers, Inlets, Sea Chests
Where to start?
According to the size of your vessel, we will recommend which system is best for your protection needs.
- You will need to provide as much information as possible about your boat, including general schematics, manuals, and information about the construction of your hull.
- Pragati Yacht's engineering department will analyze the schematics and develop the installation plan according to the boat's location.
- If you are local, we can provide you with installation service, carried out by a marine engineer with extensive experience working on Mega Yachts as a chief engineer. We will guarantee the installation of the system and monitor the effectiveness of the system.
- If you are not local, we can travel to perform the installation wherever your boat is located, charging for the mobilization service.
- We can also provide a step-by-step installation manual to a competent person or company and provide virtual support via video call and emails. We are not responsible for installations carried out by a company other than Pragati Yacht.

Alejandro and Juliana installed 2 x Quad SoniHull systems on my 50' power cat; Since the units were installed growth has always been very light - I keep my boat in a marina with excellent water exchange so plenty of opportunities to grow stuff. I've been very pleased. After the SoniHull install, and without thinking about it, I asked Alejandro to debug my anchor windlass and install a new S/S chain - without mentioning that this isn't normally what they do, they just got on with it - in addition he debugged the problem that has been plaguing the windlass since new - it would run for 20 seconds and then the breaker would trip. Turns out the factory had botched the installation of the switch too, the facttory had installed wire that was a couple of gauges too thin causing it (and the breaker) to drop voltage and overheat. Alejandro replaced the switch, cable and breaker (in addition to finding a couple of loose connections - again from the factory) and since then the windlass has worked flawlessly. I would recommend these guys without hesitation.Posted on Google![]()

It's been about 6 weeks since they installed Sonihull on by boat. As of today, there is not one single barnacle on my boat. I was at the sandbar today and dived in with a mask... and the bottom paint is still like new. I'll update if anything changes. Thanks guys!Posted on Google![]()

It’s been three months since our professional Sonihull Duo installation. I’m delighted to report that the system is working as promised in an environment high with marine growth. My bottom shows no barnacle growth with light and smooth Algae covering the bottom as verified by my hired Diver. While treated with anti-fouling paint it proves out how both applications work together successfully. I’m the owner of the new Boston Whaler Outrage 330 that I took delivery in early April. Juliana Gómez-Leach and Alejandro representing leadership at Pragati YACHT were nothing less than professional from education to installation. We can not thank them enough for traveling to Bohicket Marina Village, Seabrook Island, SC. to complete the successful installation project.

I have had this system for a couple of years , due to my hull multi Kevlar layers on my Neptunus the transducers had to be moved which Pragati supported at no cost . It made a 180 difference , I used to bottom clean every 4 weeks , now after 90 days only a little algae growth on the water line which is easily removed . My last paint job made it 4 years with 3 years without the system and one year with it . With the system now I don’t believe I will need to repaint for at least 6-8 years . Also it is affecting the swim platform which I didn’t think it would , which is a great additional benefit . Thank you for Pragati continued support 😀Posted on Google![]()

High level of professionalism on time. They provide solutions to clean sea growth build-ups in open cooling systems, pipework, and heat exchangers, and at the same time, eco-friendly solutions to prevent it and therefore avoid unplanned maintenance. Besides they assess and provide solutions to potential galvanic corrosion due to different electric potential metals and other services.Posted on Google![]()

They installed Sonihull system 1 year ago and I have had no barnacles and zero problems. I was skeptical at first but now I have lived with for a year and have proven results Highly recommend I use them for bottom cleaning and they are great I mean really great! alex is great as the installer tech!Posted on Google![]()

I had this product installed a little over 1 year ago and it really works. We pulled boat and only growth was on running gear. Noting on the bottom of boat where this product does its work. Algae was only thing on bottom. Cannot stop that. Overall a great saver of fuel and much better ride.Posted on Google![]()
