I was thinking the same as I read down the thread. But your choice could be improved by using a double hull design with a woven kelvar mat between them.

I hope you aren't talking aluminum...

It's used widely in commercial circles...the vast majority of utility boats built for the US Government are aluminum as well as work boats for the oil industry, etc...etc...
