A little more research on this says that the boats are actually about 200 yards apart from each other in a triangular pattern and they keep returning to the same areas and digging those same spots. 3 boats and 15 or so crew members. It definitely sounds like they are on to something. When wrecks go down, sometimes they will break into parts and this could be what we have here. Maybe they have found the major parts of the wreck and each boat is digging on one of the parts. With the share price being low and the operations being where they are I don't think there has ever been a better time to buy.
