Sonihull Ultrasonic Anti-Fouling System

Single Transducer for Yachts Up To 32 Ft.

The ultrasonic antifouling system by NRG Marine uses the latest digital electronics and ultrasonic transducer technology. This system works by producing multiple bursts of ultrasonic energy simultaneously in multiple frequencies, the energy creates a pattern of alternating positive and negative pressure. Microscopic bubbles are created from the negative pressure, while the positive pressure implodes them due to formations of vapor cavities known as cavitation. The result of the implosion is a micro jet action that creates a cleaning effect on the hulls surface below the waterline. It also resonates and destroys single cell organisms such as algae. Removing the initial link in the food chain prevents barnacles and other marine life to feed on the algae.


  • Environmentally friendly, does not introduce metals or chemicals to the environment.
  • Cost effective, less frequent haul outs and cleaning.
  • Increase efficiency, saves fuel when motoring & faster speeds when sailing.
  • No hull penetration required
  • Easy install
  • Automatic voltage selection between AC and DC, defaults to AC when short power connected.
  • Auto low voltage cut off in DC operation.
  • Effective removal of a wide range of algae
