Thanks Ric---I did find a chart , and it appears that the area off the shipwreck had the deepest area. ( it figures) 914 feet to 3200+, then to 4000. So, the stern of the NC and any large parts of the Electra that were there, could probably be in very deep water. Seems the transition from ocean bottom to the upper reef ledge (900 feet) is fairly steep, Reminds me of the Napali coastline on Kauai. If this is true, then this really is a needle in a haystack, and might prove to be virtually impossible. Any thoughts?
