If you're serious about getting into the "Shipwreck" business I can provide some assistance. But first, decide where your interest is most desirable, i.e., wooden sailing vessels or modern era, i.e., WWI and WWII, as an example. Choose precious metals or strategic metals, copper, rare earth, etc. Ask yourself if you have the discipline to stick with it... because it matters. I will be making available thousand of pages of research. Mostly modern, but some 15th through 17th century wrecks. As an example I-52 and ULTRA Intelligence (broken German and Japanese codes) research alone is +/- 5,000 pages. I'll throw in a WWII Japanese shipwreck with 600 gold bars, which you or someone else take it from there.
