I have the most trouble with the waterline/chine and the bottom of the V in the stern - hard and soft growth. I usually only take the boat out of the water 2 or 3 times a year for service - for a week to 10 days at a time.

A couple of questions:

Since it is a planing hull and I have someone cleaning the hull monthly - am I stupid to use ablative paint? Seems like I may be accelerating the ablative process by running the boat fast and scrubbing the bottom.

Am I better off with a self polishing paint like Micron 66 or a true hard bottom paint? I am intrigued with the idea of using a good "hard" bottom paint so I can possibly pick up some speed and fuel economy. But since I pull the boat out of the water a few times a year then that may be a mistake if that kills the effectiveness of the paint.

Any recommendations on the best bottom paints in areas like Charleston for planing hulls???? Thanks a ton for the help and feedback! I am beginning to think bottom paint is trickier than prop science.
I'm in the Chesapeake Bay with a 24 foot CC. My boat was wet slipped from last April 15 until last week. I started the season with Micron CSC, and I've been really happy with it. I run the boat pretty much every weekend, often both days, but it gets essentially no water movement in the slip (it's right on the bulkhead). I get a little scum buildup/discoloration on the sides and stern at the water line, but there is otherwise no growth on the hull. I brush the sides and transom from the boat every so often. I pulled it out twice for service, and the bottom is in vary good shape. There was a lot of growth on the unpainted transducer, engine bracket below the water line, and trim tabs, including barnacles, but I painted the transducer with transducer paint (there is such a thing, it turns out), and primed the underwater part of the engine bracket and the trim tabs with Interlux Primocon and painted them with Interlux Trilux 33, which is made for metal. I've had no growth on the transducer, engine bracket or trim tabs since then, although I do brush them off from the boat every once in a while.

This was my first year with bottom paint - the boat was new last year, and I kept it on a trailer. FWIW, I have noticed no difference in top speed or time to plane with the bottom paint.

I'd be interested in what paint you're using. I've been very happy with the paint I'm using and I haven't had the need to hire a diver to clean it. But the Bay is more brackish water that the Atlantic on the SC coast (especially this year with all of the rain), so the same paint may be less effective where you are.

I grew up in Charleston and have a friend there with a 34 foot CC that is in a slip at Toler's Cove in Mount Pleasant. He repaints every 18 months or so and has a diver clean it about once a month. I'll see if I can find out what he's using and if he's happy with it.
