I am a fisherman on the James River in Virginia(Richmond to Norfolk to be precise), and I have a boat and sonar, the whole nine yards. I know there are wrecks galore in the river, ships have been in it since 1540. But anyway, I want to see if I can do some sort of small scale recovery, does anyone do this, is this idea sane, what problems are there,etc? I know of some wrecks already(fish hole in them) that I fish, why not?
