Foul release coating VS self polishing antifouling

In the Clean Hull Project, 30 test boats in the Oslo fjord were coated with foul release coating, inspected during the 2022-season and cleaned by hand. We accidentally ended up cleaning a boat covered with traditional antifouling paint, which turned out to be a perfect opportunity to showcase the very difference between the to types of fouling control. Traditional self-polishing antifouling is made to slowly release biocides and polymer binders to the water column. Foul release coatings are a non-toxic alternative to self-polishing antifouling, that creates a slick surface area that fouling loosely attaches to. We have covered the differences in the following article: https://fjord-tech.no/2023/04/14/foul...
