Powerboats

Installing the Ultra Series II Ultrasonic Antifouling system to your powerboat will help to maintain the hull speed through the water and manoeuvrability, by reducing drag. Keeping the hull clear of growth reduces passage times, saving fuel and money. It can take up to 30% more fuel to push a fouled hull through the water – a significant factor for motor boats.

The hull waterline length (LWL) is the main determining factor for the number of transducers that should be installed to the inside of the hull.  Longer hulls will have a much larger underwater surface area to be considered for protection against fouling, so additional transducers will be required according to its length.

While sound waves are resonating throughout the hull form because the transducers are fixed to the inside of the hull, the stern gear (propellers, shafts and stern drives) are acoustically isolated from the sound within the hull due to the seals used in their attachment.  In the proximity of a transducer, the ultrasound signal also dissipates out into the water in an 180o arc below the hull surface.  Therefore, with correct positioning of transducers, the system can also help to some degree in keeping the stern gear clear, although not quite so effectively as the hull.

No through hull drilling is required, so the system can be installed with the boat in the water.
