During the last hurricane, a ships keel was sighted across the dune line near Normandy beach. Tommy Gore saw it, as did I. (some idiot desk jockey archaeologist at the state identified it as a "bridge timber, but that's another story). Not 1715, but wood.
Anyhow, here's the "whole truth". Through sheer serendipity, a heavy equipment operator on a project I was working on started talking to me about beach treasure hunting. He told me that, after the storm, he was on the beach and saw the 60+' timber on the beach. He took a piece of equipment out there and dragged the timber across the dune line! Same dam keel Mr. gore and I saw. I went on the beach and saw ALL the rest of the keel pieces, including curved stem pieces. I salvaged on piece, and mother nature recovered the rest. Unfortunately, since the friggin' state bozo screwed up his identification of the keel, it has been lost forever, probably went to the dump.
Yes, I'm pretty bitter. These armchair maroons think they are Gods gift to the salvage world, but they appear not to have enough sense to pour "it" outa a boot with the instructions on the heel.
BTW, the ship was the "America", which, ironically is on the state master list of historic sites.
