As your article says, Florida loves tilt up. It is a fast way to get

but it went away just as fast. I am not sure what happened there.
That is interesting stuff (air entrained) it floats.

I wonder if you could adapt it to ferro-cement boat building?

That may be the same stuff.

No its not, YTong concrete is autoclaved, ferro
cement boats can't be, they are too big for that.

you just need a big enough kiln.

Not enough would build a boat that way to warrant doing that.

The panels I was looking at were 8x16
feet. That could have been a 16' boat.

Nope, because the boat is much thicker.

These were 16' x 8' x 8" thick panels and I bet they were not cooking
them one at a time.
Stuffing that 16' boat in that kiln would be trivial.
You cpuld park a transport truck in many autoclaves.

The Boeing autoclave for the dreamniner components is 30 x 75 feet. -
total volume over 82000 cu ft. - Built by ASC Process Systems.

Runs at 450F and about 150psi.

Hutachi built another one in Japan for Boing that is 98.5 feet long
and 30 feet in diiameter./ Could make a pretty good sized hull in
either of those!!
