Interestingly concrete yachts are a thing. Ferro-cement is the term, but it is just reinforced concrete. You can buy very large yachts for small amounts of money with yachts made this way in the 70s.

It is very expensive to prove a ferro hull to be sound, which is a requirement for getting insurance.

Except the steel armature inside can turn to hidden rust and if you do something and crack the ferro hull they can be a total loss. A lot were home built so finding a quality build is another issue.

There’s a reason insurance won’t touch them.

Reminds me of "pykrete" which was also a potential construction material for ships (notably aircraft carriers) proposed during WWII:

You could do that today for cargodrone boats sintering or epoxy glueing beachsand?

Or melt the sand and form it into long strips, fibers, then glue the fibers together in some sort of glass-fiber-epoxy type material. Get the patent done quick because that sounds viable imho.

Glass fiber? Ridiculous, that'll never work.

Was this created by AI and not proofread or created by a human and not proofread? The paragraph relating to the Musgraves taking over a factory is repeated and it reads rather oddly.

Anyway, regardless of that nitpick, it was an interesting read.
