Ultrasonic Anti-Fouling

What is Algae fouling?

Micro-organisms and bacteria that are borne in water multiply very quickly after they have attached themselves to the submerged area of the hull creating a layer of "slime". Algae cells themselves act in a similar and then develop into the complex structures we know as seaweed. It is this environment which then provides an ideal food source for the spread of barnacles and other similar creatures as they are given a surface which is deemed suitable for them to attached themselves on to.

How Does Ultrasonic Anti-fouling Work?

The ultrasonic anti-fouling system works by simply emitting a low powered pulse of ultrasonic frequencies across the hull which has been submitted to the fouling. This is controlled by usage of a digital control unit from which the device uses transducers to deliver the pulse therefore creating what is effectively a "sound board" making it difficult for the targeted micro-organisms to thrive and therefore eliminates their fouling from the hull.

The transducers are fixed to the internal side of the hull to isolate them from the stern gear, this is achieved by separation using a seal. With correct fitting and setting up the signal dissipates into the water also keeping the stern of the hull clear from fouling.
