According to petermac in a private message I had this all wrong, so I will attempt to get it correct this time.

This is a picture of a bogged loader, looks like he was using it at low tide to move the dredge hose around on the shore, although I'm only speculating as I didn't actually see him doing it. The picture was taken at approximately friday 9.15 am from the Bent Street boat ramp.
