Interlux Micron CSC and Micron 66 are both ablative paints. From advertisements:

"Micron CSC is an great multi-season ablative bottom paint with a copper-copolymer formula that provides controlled release of antifouling biocides at the paint surface.The longevity of the coating depends on the amount of paint applied. CSC retains its effectiveness even when the boat is removed from the water for extended periods (winter storage, for example). To reactivate come springtime, use a stiff brush or powerwash lightly. Suitable for sailboats and power boats."

"Unique among ablative bottom paints, the acrylic copolymer formula of Micron 66 with Biolux® reacts with saltwater at the paints surface to release biocide and prevent marine growth. Because the formula relies upon a chemical reaction and not water friction, Micron 66 is a great choice for boats that remain stationary in their slips for long periods of time. Micron 66 self-polishes and becomes smoother with use. This reduces drag and fuel consumption. The polishing action of this paint also reduces the need for sanding when the time comes to repaint. Unlike boats painted with traditional hard antifouling paints, boats painted with Micron 66 can also be hauled and re-launched without a need to repaint. NOTE: Micron 66 is not suitable for use in freshwater."

I keep my boat in the water 10 months out of the year in the lower Chesapeake Bay and in an average-to-high marine growth environment. I have always used "Interlux Micron Extra with Biolux" and have had very good results. One year I tried Micron 66 because I couldn't get the Micron Extra. The results were even better! When I hauled the boat at the end of the season the bottom looked like it did the day I launched it - smooth as a baby's ass! However here's the caveat - I found the Micron 66 is amazingly difficult to work with. It almost dries as it's going on and it skims over very quickly in the can or the tray.
