A greener solution to antifoul paint
Copper compounds are applied to the hull to prevent organisms
from settling and adhering to submerged components. However, the poisons within these can leach dangerously into the water. While the environmental impacts of such a practice may seem worrying now, prior formulations were even more damaging.
Ever since the Roman days, boat owners have tried numerous systems to prevent sea growth from building up on the hulls of their vessels. Modern antifouling paint is credited to the Bonnington Chemical Works when they began marketing copper sulphide anti-fouling paint around 1850. Other widely used anti-fouling paints were developed in the late 19th century, with some 213 anti-fouling patents being recorded by 1872.
As this science evolved, these antifouling paints became better. Better at keeping boats cleaner for longer but also better at killing our pristine marine environment.
It wasn’t until the Convention on the Control of Harmful Anti-fouling Systems on Ships (AFS Convention), which was adopted in 2001 and came into force in September 2008, that the use of TBT (tributyltin) antifouling paint on ships was finally banned. This has greatly reduced the effectiveness of today’s antifouling paints and as a consequence, its application is now required more frequently.
Modern antifouling paints rely on cuprous copper oxide as its killing ingredient to keep a boat clean. As this is how it keeps a boat clean, it is obviously not good for the waterways that these boats live in and pass through.
After 150 years of trying to kill the oceans with this stuff, it is about time we looked for a more long-term and sustainable solution. If it is also a financially beneficial option, then it becomes a no-brainer. So is it possible to come up with an alternative to toxic, poisonous antifoul paint that actually costs less than applying such a lethal concoction of chemicals every year to your boat? Continue reading, there may actually be an answer.
FAB Dock is an inflatable dry dock system that can safely keep your boat clean and dry when not in use. With your pride and joy sitting pretty inside your FAB Dock, antifoul paints are redundant, as those pesky barnacles aren’t afforded the chance to cling to the hull.
