Hi Darren, Maybe we should divide wrecks into five categories .Too deep .Too expensive (Governmental red tape-overburden-plant required,etc.) .Too vague .Too hammered (easy access-shallow water,etc.) .Others This last category may be worth considering.Contents of holds may have some material that has had a low value for years ,then market prices zoom.For example, there is a shipload of chrome ore near my town which has been neglected and may rise in value one day.Another way is to re-read salvor efforts and see if they are overlooking valuables. For example(and I`m probably giving this away to the salvor), read Barry Clifford`s'The Black Ship' covering the salvage of the 'Whydah', and tell me what he is passing up at present.
