Bottom paint
I plan to use Interlux Micron CSC or CSC plus. I used Micron CSC on my last boat (16'Compac)and it looked good after several month on a mooring. It cleaned up well with a power wash. Plus if you plan to trailer you don't have to worry about haulout and relaunch. The other thing is these paints wear away and you don't need to worry about about stripping the buildup.I just bought a Catalina 22 that was fresh water only. Plan to apply a barrier coat and then bottom paint before launch this year.
