Much earlier, too. The "S.S. Palo Alto" is semi-permanently anchored at the
end of a pier in Aptos, California. Known as "the cement ship," it was
built for WW I, but completed in the early 20s, and then sold as an
amusement park/gambling ship and anchored in its current location in the
late 20s.
Storms have damaged it.
Incidentally, most such ships are filled with rebar and chicken wire, so I
wouldn't give a steel penny for the supposed invisibility of such ships.
Not that steel vs. concrete has anything to do with showing up on sonar:

A new set of laws of physics?
