I ran aground on a sand bank with my Trawler. Called boat us. I am 80 yrs. Old and was pretty shook up. The boat operator convinced me that I was in a salvage situation because he would have to dig a hole under the boat to get it off. I went with his assessment expecting at least a couple of hours of work. 10 minuets of prop wash digging at a moderate throttle tied off to my boat and MAGIC it floated and only cost $ 6178 .
