SonicShield uses pulses of Ultrasonic frequencies to deter micro organisms from attaching themselves to your motor boat or sail boats hull. The removal of these micro organisms is important in the antifouling process as their presence create a habitat / food source for larger aquatic organisms such as barnacles.

The Ultrasonic frequencies are delivered to the boats hull through a series of transducers that are attached to the inside of the bilge area meaning no through hull drilling is required.

The transducers are then connected to a control unit that is intelligently controlled to ensure the optimum power (12v/24v or 110V - 240V) is supplied for maximum cleaning efficiency.

The pulsing of the transducers creates areas of negative and positive pressure resulting in micro jets surrounding the boats hull leading to the destruction of the single cell micro organisms (Algae). This pulsing effectively creates an invisible shield around the boats hull protecting it from these micro organisms commonly referred to as Bio-Foul. This Bio-foul is the first stage in the overall marine food chain and the removal of such Bio-foul results in the removal of the food source for larger aquatic wildlife such as barnacles.

The ultra high frequencies are not harful to humans, fish, plant life or any other marine based life forms.


It is a well known fact that there is a direct link between a hulls cleanliness and power/fuel requirements. Traditional antifouling companies have ‘widely regarded that a heavily fouled hull will have the same affect on fuel consumption (and/or loss of speed) to that of rough weather conditions.'

In a sailing yacht this increased drag on your boats hull will limit your hulls natural potential and can create problems when berthing.

In a motor boat the increased drag will dramatically increase your fuel bills and running gear/engine maintenance costs due to the unnecessary increased work load of your engine.
