I'm sure the topic of paints has been done to death but I can't seem to find a good recommendation for what manner of bottom paint to use on a sailboat thats going to be trailered most of the time. A good ablative anti-fouling seems the thing if your in the water all season but what if you keep it on the rack most of the time? A friend of mine (powerboater) even suggested that I may not need to paint the bottom at all. Is that a good idea?
