how did you cut out foam?

I did not closely monitor the progress but there was a guy removing the foam from the hull of a 16' Mckee using a Awesome Auger ( the device the late Billy Mays advertised to plant flowers. It seemed to work well and the waste was small enough to remove with a shop vac. He did the whole boat in a long Sat. of work. Was a lot of foam scrap in the dumpster when he finished.
