When determining the correct solution for your boat the main consideration is water line length.

For boats < 10M CMS Marine recommend the SonicShield II.

The system comprises x 2 Transducers, both being located 1/3 from the Stern on opposite sides of the engine. This solution gives optimum cleaning performance to hull and peripherals i.e Rudder and Prop / running gear.

Catamarans / Larger Vessels / Commercial Vessels
CMS Marine would suggest that x 4 Transducers are used on a Catamaran with a water line (each hull) of < 10M. This can easily be achieved by purchasing x 2 SonicShield II units (x 2 control boxes and x 4 transducers). To enquire about this set up or to discuss a bespoke solutions please give us a call.

For Catamarans with a waterline of between > 10M and <20M there are a again a multitude of options available. CMS Marine would suggest that the 2 to 3 ratio was maintained and so would suggest that x 6 Transducers are installed. The standard procedure for supplying a Catamaran of this size is to purchase x 2 SonicShield III units ( x 2 control boxes and x 6 transducers).

To enquire about this set up or to discuss a bespoke solution please give our sales team a call.


The ultrasonic frequencies require a solid structure to resonate around the hull of the vessel and for this reason the Steel / Metal hulls found on larger commercial vessels make the ideal location for the SonicShield units. The effects of down time / maintenance of larger commercial vessels has a much larger financial impact than to the recreational boat owner and so it is essential this down time is limited to the bare minimum.

By installing a bespoke solution by CMS Marine your vessel can benefit from increased hull efficiency and lower maintenance frequencies. For a bespoke quotation or to discuss your requirements with one of our technical team please give them a call. The fundamental development of this product is based around the power supply to ensure an optimum balance is obtained between power usage and cleaning efficiency.

In a large commercial vessel the additional power available can be harnessed to deliver maximum power to the transducers, our technical staff would welcome a discussion on how this maximum power can be achieved on your vessel.
