Boat owners know the effects of a dirty hull. Instead of a smooth, clean boat hull slipping through the water, marine growth and barnacles create drag, reducing speed. Extra demand on engines to maintain speed means increased fuel use, an added cost regardless of vessel size. Fouling is the result of marine growth, a constant process which starts as soon as the boat enters water. Fouling occurs even on a newly painted clean hull treated with the finest toxic paints.
