The program or data wont do you any good unless you have stories from survivors and a aprox long and lat and the conditions,wind waves,currents and no real storm data.Alot of ships sink at sea with no traces of survivors or debris.In the case of the SS central america they got lucky,even had other ships picking up survivors with the long and lat of their locations so they could figger out the drift.
I have all this data from survivors, by other commanders of other ships of the same fleet. etc. and then?
