I use a soft sponge for my ablative paint. Scotch bright works for the prop and shaft but seems too harsh for the rest of the bottom. A soft sponge willknock off most stuff and doesn't remove that much paint. Again my bottom is ablative. It can be done with a snorkle but I scuba dive and it is much easier that way. I stress that you do not want to scrub off the paint!!!! The whole ideal of an ablative paint is that it comes off easily so that nothing hard can attach to your hull. Once you start getting hard growth the boat needs to be hauled and repainted. Hard paint is different. Once the copper leaches out the paint is useless and stuff will grow. I have never found any hard growth on top of ablative paint. The sponge is just to remove the slimy soft growth that will slow you down.
