Is that one hull or both?

Aluminum weighs .098lbs per cubic inch. A plate 12"x12"x.125" would weigh 1.764lbs. If there's roughly 75ft^2 of area, that would be 132lbs if my math is correct.

I can't imagine 1/8" aluminum is too friendly to work with either, or neccessary. Probably wouldn't need any bulkheads though! You could probably use 1/16", or likely even less.

I'm not actually looking to pursue anything, I don't have the money or the resources to build or have anything built. Just mental masturbation.

This thing is flat out beautiful though!

The skill and craftsmenship it takes to build a polished aluminum body is just amazing.
