Ultrasonic anti-fouling system (for boats < 10 m, DC power supply)
ULTRA 10 DC Ultrasonic Antifouling

The Ultra 10 DC unit operates on a 12 - 24 volts supply. It has one single transducer and is suitable for boats with a waterline length of up to 10 metres.
The solution is simple!
The Ultrasonic Antifouling unit destroys algae and prevents barnacle growth, so they don't attach themselves to your hull.
How Ultrasonic Antifouling works
The control box sends a variety of pulsed ultrasonic signals to the transducer, which in turn emits a series of low power, low frequency sound waves which are virtually inaudible to the human ear. They create a wall of moving water molecules over the whole of the submerged hull. The micro - environment which exists as a result, destroys algae and barnacles so they don't attach themselves to your hull. 'The science' is in the differing frequencies and the harmonics set up within.
It's as simple as that and it works!
