Sonihull Marine Transducers


The Sonihull ultrasonic antifouling system by NRG Marine uses the latest digital electronics and ultrasonic transducer technology. This system works by producing bursts of ultrasonic energy in multiple frequencies, the energy creates a pattern of alternating positive and negative pressure.

Sonihull is a cost effective antifouling product that works alongside a conventional antifouling paint with additional benefits.
In addition to reducing annual haul out costs, Sonihull reduces growth on hull, stern gear, and bow thrusters. A clean hull will substantially reduce fuel costs while keeping the boat performing as it should. Sonihull systems produce multiple bursts of ultrasonic energy in a range of targeted ultrasonic pulse frequencies. This produces a pattern of alternating positive and negative pressure, whereby the microscopic bubbles that are created during the negative pressure are imploded when positive pressure is applied.

How the Sonihull System works?
The implosion has a cleansing effect that destroys algae, the first link of the food chain, making the surface less attractive to other marine life that feed on the algae. This microscopic movement of water also prevents barnacle and mussel larvae from embedding.
Sonihull works on GRP, composite, aluminum, steel or carbon hull material, but not on wood.

Reduce your carbon footprint!
With new environmental regulations set to substantially reduce the effectiveness of traditional antifouling paints, PYI Inc. offers Sonihull Ultrasonic Antifouling Systems as a pro-active addition to traditional antifouling methods. Using the latest in digital electronics and transducer technology, Sonihull has made a quantum leap forward over the competitors to fill the needs of the marine industry.
Tests have demonstrated that electronic antifouling products have no adverse effect to fish and marine mammals. The ultrasonic frequencies stay very close to the hull structure and it is demonstrable that the signal does not stray into open water.

- A clean hull and drivetrain can reduce fuel bills by 20% - 30%.
- Reduced vibration and improved performance.
- Reduce maintenance costs and expensive haul outs.
- Suppress diessel bug and keep stored water fresher.
