By the first half of the fifth century. A.D. Ship D, a medium-sized river barge, sinks, closing the sequence of known boats: it is in fact the last sinking of a boat within the excavated context of the shipyard of ancient ships. The ship was found completely overturned, almost completely devoid of the keel but with much of the dead work (the part of the boat's hull above the waterline) still intact, as can be seen in the museum.
