Wherever there is unwanted marine biofouling. From tugboats to oil tankers, wind farms to fish farms, Sonihull is working with industry leaders to create cost-effective ultrasonic antifouling solutions that reduce drag, cut fuel consumption, increase service intervals and leave no poisonous environmental legacy.
Key Features of Sonihull Ultrasonic Antifouling
Effective bio-fouling without the poisonous environmental legacy of biocides or microplastics.
No drydocking, no through-hull fittings, no expensive Impressed Current Antifouling copper anodes to replace.
No cleaning hard-to-reach areas, extended maintenance intervals, less downtime and reduced running costs.
Inaudible to humans and marine life with no interference to sonar and electronic equipment.
Lower Fuel Consumption
Clean hull, propellers and rudders can reduce fuel consumption by up to 30%.
Ideal for bulk storage. Sonihull suppresses Diesel bug and keeps potable water fresher for longer.
Low Power Consumption
At only 3.6 Watt-hours per transducer, Sonihull is ideal for onboard, standby or remote power.
Lower Operating Costs
Can save up to 95% of capital and MRO costs when compared to impressed-current antifouling systems.
Easy System Integration
Compatible with RS232 / RS422 and Modbus communication interface for remote control with critical path fault monitoring.
Biocides are not a long term solution
Ultrasound has already proven its antifouling credentials in the food, brewing and aquaculture industries. By 2026, any marine antifouling system that uses a biocide will have to be resubmitted for lengthy and expensive approvals.
Coating industry insiders expect that many of the current biocide systems will be discontinued before 2026, as demand grows for future-proof, biocide-free Marine Growth Prevention Systems (MGPS).
The 2026 deadline for biocide resubmission is approaching.
Prevents biofouling on all surfaces
Sonihull is a complete range of fit-and-forget ultrasonic antifouling solutions for any solid surface that is exposed to raw seawater. From hulls, shafts, propellers, and waterjets, to sea-chests, tanks, keel-coolers, box-coolers, pipework, intakes, and valves.
Unlike biocidal coatings and impressed-current systems, Sonihull is a low-cost, low maintenance and non-toxic solution to marine growth and fouling.
Are You in the Right Place?

Since 2006, over 30,000 Sonihull antifouling systems have been installed worldwide, making Sonihull the world’s leading ultrasonic antifouling specialist.
Zero environmental impact
No leaching of poisonous biocides, no shedding of microplastics from ablative coatings harmless to marine mammals and fish.
Save on running costs
A fouled hull, propeller, and steering gear will increase drag and can increase fuel consumption by up to 30%.
Reduce capital & MRO costs
Compared to Impressed Current Antifouling Systems. With Sonihull there's no drilling, no welding, no downtime and no costly copper anodes to replace.
I want to thank you for your advice to install aboard my ship two SoniHull DUO… I am, after one year, really very happy with those devices. My ship, a 65 Ft steel trawler, has stayed one full year in Brunswick Landing Marina. Here everyone sends a diver every two months for cleaning his hull off the growth, so I have asked the diver to check my hull, after one year without cleaning… The guy was really amazed by the fact that my hull was still perfectly clean… Except for some barnacles on the shafts and propellers, so my only regret is not to have installed the sonic system for the shafts as well. This system is really great and super-efficient. Thanks again for this product.

After the first week, a noticeable difference could be seen, by the end of the 4th week, the results were conclusive. The vessel fitted with Sonihull had little or no growth over the entire hull, while the other vessel was found to have so much growth the vessel struggled to get on the plane. As a result of this test, Sonihull will be included in all future standard project specifications.

Finally, I am proud to inform you that the first Sonihull antifouling system has been installed on one of the SAR vessel without any problem. We have installed two transducers on the intake of the water jests, one between engine & generator and another one in accommodation. After finding this project successful, many other vessels will be in the row.

Vigilant coming out to dry dock in Kuwait, she has been in the water for almost a year (February 2015) and is in a pretty impressive condition. There is no fouling at all.
