Well...a boat wreck. It had a fiberglass hull and was obliterated on the rocks. We found tons of wreckage including tools, pillows, cushions, antennae array, awning, Ryobie drill batteries, a full Barbecue, some gps computer, a working G-shock watch, and my $50,000 metacal bill. I didn’t have my camera for the wreck, but I will post pics of the bill. Still pretty cool to find.
