Had a weekend of diving in Seattle, and we managed a dive on a barge that sank after a collision in 1950
It was originally a wooden ferry, I think named The City of Tacoma Ferry (or Just Tacoma Ferry?) then was converted into a barge.
One end is still pretty intact but there is a lot of breakdown on the other end.
Vis was pretty cruddy, but the video seemed to come out not too bad in comparison.
