Ablative and self-polishing paint is known for being more efficient because there is a higher and longer delivery of biocide compared to hard antifouling paint. Ablating is the process of how the paint wears away after time which will prevent organisms from attaching to the hull. That is why the more coats of ablative paint you apply, the longer it will be between painting periods. Three types of ablative paints that wear away in entirely different ways are controlled solubility copolymer, self-polishing, and hybrid ablative paint. All antifouling paints will work in certain conditions, but what works well in your harbor really depends on water temp, current, fresh water outflows, and how often you use your boat.
