This is as close to a scientific, side-by-side comparison of any anti fouling coatings that I have ever come across. And it 100% supports what I have long said about Coppercoat- that it releases so little biocide that it is ineffective in areas that experience moderate to high fouling. It simply doesn't have the horsepower to do as good a job as even a worn-out mid-range ablative.
