 These have been in use in Japan for a long time. I lived in Japan in the 70's along the coast near Zushi . There was an old guy who had one of these machines and he would drive it up and down the beach from town to town cleaning out these mooring areas for the local fishermen. It was a lot of fun to watch.  Lots of people are saying that this is too slow or the wrong way to do it, that dredging would be better. But Japan only has a limited number of dredgers available. After the tsunami they had hundreds of harbours this size to repair and nowhere near enough machines to do it. Especially since many of those dredgers were also wrecked by the tsunami. So they did what the Japanese often do: they got creative and adapted what they had to hand. I think these machines are another fantastic example of Japanese ingenuity.  the Pacific Ocean: "no vehicle can drive underwater in the ocean! unless your a submarine!"
