Hi Gringodoc,
Sorry, do not take it personally, but content of your post seems to me a little strange.....As many from this wonderful Forum know, I live and work in the Dominican republic as a marine archaeologist for more than one decade already, I have been working with some treasure hunting and salvage companies here in the past and in the present and I humbly think that after 12 years here working in this field I have certain knowlege about the shipwrecks in the Dominican waters. By the way, any shipwreck, and not only that one with 30 cannons and other artifacts, is worth deep exploration and investigation.
First....You wrote that you have heard of a wreck with about 30 cannons. Then you state that you saw some of them. Did you see them in person or on video or on a photo? Did your friend take them out of the water for you to see them? Let me also tell you right now that your friend cannot ask anything for these cannons from the simple reason - any shipwreck in the Dominican waters belongs or to the Dominican Republic or to a salvage company if this shipwreck is in their lease area specified in the contract with the Dominican government and even after that, 50% from all these artifacts from that shipwreck belong again to the DR. It is strongly forbidden to take out any artifacts from any shipwreck and if your friend tries to do it, tell him to abandon that idea as soon as possible, otherwise he risks prison and huge fines. If he would notice his discovery to the respective salvage company (the majority of the territory of Dominican waters is divided among foreign salvage companies already, so I suppose that it is this case) that operates in respective area, he can generally get some reward, he could be allowed to participate in the excavation and his name could be officially mentioned as well. Iron cannon is not too much value generally itself, but it can be used for further identification of the shipwreck. By the way, pewter spoons do not mean 18th century. Recently we found pewter plates and part of the pewter cuttlery dated 16th century (also in Dominican waters).
Just a question - Do you live in the DR?
Regards,
Bobadilla
