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


There are some very large industrial autoclaves. You wouldn't be doing a
Queen Mary but smaller pleasure craft like drift boats could be done.
That's where the economics breaks down. Glass is nasty but it's fast.
