I'd like to see a true high tech wood composite. *Maybe bamboo

It's called cold molding.

Been around for years.
Building a cold-moulded wood boat requires...well...the sort of skill
that comes from experience. But it does produce beautiful boats.
All glass boats are too heavy requiring too much fuel. *Aluminum boats
are good but welding them right requires more skill than most boat
companies can afford and they are difficult to repair.
Above the waterline, foam/glass is ok but below the water, no.
Loogy, I am not a ME but a physics geek. *Carbon fiber is currently
expensive and if such a boat was struck by lightning, the result would
be bizarre.

Since you're still interested in the subject I posted a response I had
written to Wayne but didn't bother sending.
In that "efficient boats" thread.
Some weight examples, and my view that FRP is still pretty heavy and a
new material is in order.
Pie in the sky, but maybe you can come up with something.

Transparent aluminum, of course. :)

Boron.. I remember the werid glass tubes they used to make boron
"thread" here in CT... Quite a process, pretty neat stuff. That was a
loooong time ago. I did not make the stuff, I was a sub contractor on
the facility...
