Micron 66 has excellent anti fouling properties. It is very ablative however and does not stand up well to repeated cleanings. Bear in mind that simply "leaving it alone" will mean you have a dirty bottom. It will foul. Here in the Bay Area, it is used primarily by racers and they can expect to get about one year out of it.
