Antifouling

For healthy surface water and your own health, it is better to use as little antifouling as possible. If maintenance on your boat is necessary, make sure that the product is permitted for non-professional use in the Netherlands.

What is antifouling?

Antifouling is paint containing a copper compound (biocide) or zinc that prevents the growth of seaweed, algae, and shells on the underside of boats. These products not only prevent growth on the boat, but also end up in the water. This is harmful to the aquatic environment.

Use as little antifouling as possible

The best thing for the aquatic environment is to avoid using antifouling and opt for underwater paint without biocides. Of course, your underwater paint must be tailored to your sailing behavior, mooring location, and sailing area. For example, there are paints that prevent fouling from adhering and make it easier to clean the bottom of the boat (non-stick coatings), or you can opt for a hard paint (e.g., epoxy-based) that can be brushed without damage.

Check in the spring

At the start of the boating season, our enforcement officers visit marinas to check that private individuals are using antifouling correctly. We do this to ensure that fewer harmful substances such as zinc and copper end up in surface water. We work together with Rijkswaterstaat (the Dutch Department of Waterways and Public Works) and other organizations in this regard.
