My Catalina 30 has 4 coats base + 2 coats of Interlux CRC applied. A more experienced sailor in my yard thought I could get another season out of the current paint. Unfortunately the shipyard doesn't allow owners to paint their bottoms. I'm considering painting the 12'' or so under the waterline which shows the most wear and which I could probably get away with without them noticing. Thoughts? Bad idea? Not worth it? On a normal year I'd probably just have them do it but money is tight...
