That last pic is a barge. Was a government barge that was
used when they dredged the cannal, the new cut, then it was
no longer needed around 1940 the government sank it there
and it had a good top till about 1960 as it was rotting away.
Then some one set it on fire after that date. The back 30 feet
had a concrette top and the rest was a wood deck and had a
pointed front which points north. Those long pins are bolts.
