I got news for you- hull cleaning does happen on a regular basis. Here in California, boats are cleaned typically 4 to 15 times a year, depending on location. They haven't yet invented an anti fouling paint that eliminates fouling in regions of moderate or high fouling. (Well, OK, they have, but it's illegal now
) But you're right, we (as boaters) should all be lobbying for non-toxic alternatives to anti fouling paint. They already exist, but until copper is banned from use, they will never see a big share of the recreational boating market. They tend to be more expensive, more difficult to apply and less effective than traditional, copper-based paints.
