I say concrete canoe and people laugh. Wouldn’t it sink they always ask? Surprisingly no. Had we used ordinary concrete that is used in construction of buildings then yes it would sink like a rock, but we cheat just a little.

This does make the mix considerably weaker, but surprisingly lightweight.
