What is wrong with correctly laid and built ferrocement hulls.

I am sure there are proper uses; the technique has been used to
created barges in the past.

There was a craze for ferrocement in the 70s. (A decade that also
favored disco, polyester clothing and bad hairdos.) Rationality
returned when it was discovered that they were not as cheap as touted,
difficult to fair, have dubious longevity and are next to impossible
to insure.
