When I was a little kid in Sausalito we used to go south to (I think) Santa Cruz. There was a beached concrete freighter hulk there that had been turned into a sort of amusement pier if memory serves. My mother or somebody told me it had been built by Kaiser as a prototype freighter but I can't remember for what purpose. I was just a few years old so the thing seemed huge to me but I'm guessing it wasn't actually all that large. I have no idea if it's still there.
PS-- So I just looked it up and apparently it is still there.
Believe it's off Aptos
The ones that were used as breakwaters are WWII liberty ships. There is a good article on them in Wikipedia. 2,700 of them were built during WWII as war supplies transport ships. The average build time was 42 days. Many became breakwaters and artificial reefs after the war.

Maybe I should have said many, a lot on the East Coast are. Have dove on several liberty ship artificial reefs and there is a good example of a breakwater built from them at the entrance to the harbor of Cape Charles, Virginia.

Ferro-cement the was a favorite building material for amateur boat builders for many years. They thought it would be an easy cheap material to work with. It just made crappy boats that soon bled rust through the concrete. Back in the 1970s there was a company that made ferro-cement houseboats on the Miami River. They went bankrupt pretty quick.
All new(er) house boats in Holland (and there's a lot of them) have concrete tubs. Done right they require no maintenance and last (almost) forever....
Of course "done right" means the right mix, additives metal reinforcement design.....etc etc.
I am indeed not aware of concrete tubs in salt water.
