development in New Zealand.
Until 2012, when the owner of a 40ft fibreglass hull Riviera fitted an ASM V40 four transducer hull-mounted
ultrasonic fouling system to his boat after cleaning, no one had been able to successfully stop this invasive species growing up to 100mm per year
on their hulls Six years after installation the hull protected by the ASMP-40 remains tube worm free.
