If I'm not mistaken, Interlux Micron comes in 3 formulas. One for salt water, one for fresh, and one for brackish. Josh's experience would seem to confirm that. Be sure you get the right formula for your local conditions.
Addressing the original question of hard vs. ablative paints: I live in an area where the boat stays in the water for more than a summer - usually 3 or 4 years between haul outs. I'm a believer in ablative paints. They are self-polishing as you use the boat. They come off with a pressure wash instead of sanding or chemical strippers when it is time to repaint. And if you put a signal coat on the front 1/3 of the boat and the front half of the keel and rudder (a color of paint that contrasts with the second coat) the paint itself will wear away and when the contrasting color appears the paint itself is telling you there is a need to repaint. My racing friends put on hard paint like Baltoplate and then burnish the majority of the paint off (every year) to make the bottom smooth. I can do a bad tack and lose more time in a race than I would ever gain by having the boat smooth as a baby's bottom. So all the work of an annual bottom job with hard paint just doesn't seem to be worthwhile for me. Both my boats have a base coat of Petit Trinidad Pro hard paint (as a primer) and Petit Ultima SR 60 (it used to be called ACP 60). Local opinion is that the Petit paints seem to last longer in the brackish & salty waters of coastal Carolina.

I had been using Micron CSC however the 66 was even more effective as it had bioscides that prevented the 'slime' that forms on our hulls later in our sailing season. The first year the boat was hauled with the 66, I was present when it came out and asked the yard staff not to pressure wash the hull......there was no need to.....even the boatyard staff remarked how clean the hull was after 6 months in the water.....they asked if I had a diver clean it during the season which a very few do. I asked the 'Binnacle' if they would bring the 66 in and was told it was too much of a hassle going through all the regulatory hoops because of the paint's bioscides and after all their efforts, they might now be successful. Canada has restrictive regulations on pesticides and herbicides and the bioscides in the 66 get caught up in these restrictions......back to CSC and a pressure wash.

Unfortunately it requires a high salinity environment. The water in my area is only half as salty as the ocean, the paint seemed to work fine during the season but during the end of season haul-out the water used to pressure wash was fresh. A day later all the paint peeled off in large sheets the size of my hand. It made for easy re-painting. The manufacturer was in disbelief, sent a rep to look at the boat, and since the paint was applied by a certified boatyard the manufacturer paid to repaint at no cost to me. I believe they used micron csc as a replacement. Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
