Jack, I am on City Island, also. I have gone crazy for years, especially with a constsnt layer of brine shrimp and slime. This year I took Practical Sailor's advise and changed to COPPER SHIELD SCX(TM) - Multi-Season Boosted Ablative - 45% Copper by Blue Water Paints. I barely have to clean at the water line, and the keel is clean from May till September. The only downside is that you have to order it on-line, even though it is manufactured in NJ. I can't recommend it any highly. Jerry Schilp Pleiades Catalina 34
