….I’ve been trying to post this reply ever since Casam posted the original question, but for some reason my reply kept getting blocked. I’ve had a Scrubbis for some time which I use occasionally. It’s reasonably effective on the flatter, less rounded parts of the hull, less so on the more rounded bits because the natural stiffness of the sponge head doesn’t follow the contours of the hull very well. Also it’s quite difficult to judge where you’ve scrubbed without missing places, particularly well below the waterline. It’s also hard work, the sponge head generates quite a bit of buoyancy which is hard to push against. Personally, having used the device I still rely on a mid-season lift-out and power wash to keep the hull clean; you can check the anodes at the same time.
Hope this helps!
