UK-based firm NRG Marine, manufacturer of Sonihull ultrasonic anti-fouling systems, has been helping the ‘Green Marina’ project in Norway reach results - with its studies focused on a zero-toxin approach to leisure boating.
The three-year project has shown that a combination of just three eco-friendly measures will keep a hull in perfect condition and free from marine growth.
The World Wildlife Fund (WWF) is a close partner of the ‘Green Marina’ project, which is in the middle of its trial at Vollen Marine Centre near Oslo. The project is funded by The Norwegian Environmental Agency and the Norwegian Research Council.
Anders Øgaarden, coordinator of the ‘Green Marina’ project, said, “In our opinion, the combination of three key elements: a low friction coating, the Sonihull ultrasonic anti-fouling system and a boat-washer, is a win-win-win for boat owners and the environment.”
He continued, “Firstly, there is a one-time application of a durable and slippery hull coating. In addition to avoiding the VOC emissions during application, our tests have shown that boats will also benefit from significantly increased speed and a reduction in fuel consumption.
“Secondly, the Sonihull system prevents the settlement of macro-growth on the hull (weeds, barnacles, mussels etc). Any remaining light slime or small cases of micro-growth are easily removed by the third element, a regular pressure wash, or in the case of Vollen Marine Centre, Drive-in Boatwash’s Bigwash 16 hull washer.”
Øgaarden concluded by stating, “100% eco-friendly, faster boats, less fuel used, a sealed/waterproof hull, reduced costs for the boat owner, more time boating and less time spent on boat maintenance. There is no downside. A ban of copper biocides in marine coatings is inevitable. Research and development of alternative solutions is key in order to obtain a sustainable marine environment.”
