Nautical sustainability: contribute to the preservation of the oceans with your boat16/11/2021
Ecological fabrics for boating: a sustainable choice26/11/2021
Keeping the boat’s hull clean and free from biofouling not only increases the life of the boat, it also protects the marine environment.
Biofouling is a process that naturally affects boat hulls. This happens because, during the life of a boat, microorganisms, plants, algae or animals adhere to the hull, forming a layer of organisms. These, in turn, are considered invasive aquatic species. Therefore, they not only harm the functioning of the boat, but are also considered a threat to the marine environment.
Why is biofouling so harmful?
The intrusion of these organisms into the hulls of boats is harmful for a number of reasons. The first one is linked to the marine environmental imbalance. This is because these species, which have a high survival rate, spread in the ocean and reproduce easily. Thus, they establish a host population outside their natural habitat, unbalancing the food chain and the marine environment.
In addition, these organisms damage boats and slow down boats. This generates an increase of up to 40% in fuel use. Therefore, it generates more pollution and more fuel expenses. These alone are significant reasons to avoid biofouling.
How to protect your boat and the sea?
A solution on the market is able to protect not only your boat’s hull, but also the sea. Called anti-fouling products, they are materials that, when applied to the hull of boats, prevent the accumulation of these organisms.
These products can be special paints, coatings and custom-made ultrasonics to avoid these incrustations, keeping the periodic cleaning of boats up to date. The main components of these products are:
- Hydrophobic Dirt Release Coatings: These low energy coatings allow for easy release of marine organisms;
- Copper-free anti-fouling: These paints are harmless, repelling marine organisms from the hull rather than killing them;
- Nanometric Anti-fouling: These coatings create a surface so slippery that no organisms can adhere. Studies indicate that it may work, but only on boats with speeds of 10 knots or more.
