Steel Construction vessels work well with Ultrasonic Antifouling. Ultrasonic transference into the hull is very effective given the density of the material.
Aluminum construction lends itself very well to Ultrasonic Antifouling. Ultrasound signal travels very fast and well through Aluminum.
GRP Glass Re-enforced Fiber Construction
The most popular pleasure craft construction material works well with Ultrasonic Antifouling. Fiberglass has a very dense and hard final construction which allows transference of the Ultrasonic signal.
Zero Detrimental Effect
There is zero detrimental effect to any type of hull construction or vessel. Ultrasonic Antifouling transducers are not capable of causing any damage. Ultrasound is very safe. Ultrasonic Transducers also are incapable of causing Electrolysis.
Foam Core Fiberglass Construction
Consideration should be given to vessels with Foam or Balsa Core GRP. The nature of Ultrasonic Antifouling requires that the Ultrasonic signal needs to be passing through the outer layer of the hull, i.e. if there is an inner center of foam the Ultrasonic signal will not successfully reach the outer layer. The way to rectify this issue is to place the Transducer(s) in a location where both the outboard and inboard layers of GRP are bonded together. As this is usually done in only a few locations it may be necessary, for correct transducer location, to have a shipwright route out a small section of the inboard layer then prepare and fibreglass the inboard layer to the outboard layer in that location to restore the strength and seal the foam core. After this is done, the transducer can be installed as normal into this location.
Wood & Ferro Cement Hulls
Ultrasonic Antifouling will not work on Wooden or Ferro Cement Vessel construction. Both of these construction methods do not have the density to support consistent throughput of Ultrasonic signal.
Ultrasonic Antifouling is what we like to refer to as an Extender of the existing Antifouling Coating when used on Hulls. While Ultrasonic Antifouling is very effective, it is necessary to have Antifoul Coatings on your hull. For three main reasons:
- Antifoul Coatings when properly applied utilize epoxy primers that provide a waterproofing membrane for the vessel.
- The nature of an Electronic Antifouling device such as Ultrasonic Antifouling requires a consistent power supply to ensure protection. Should there be an intermittent outage or similar, the Antifoul Coating will be there to provide some protection until a power state is restored.
- Ultrasonic Antifouling is most effective as an extender, typically extending the life of existing Antifouling by 3 times or more its expected life.
