Oh. You're talking about building stuff for other people. Eff that. I'm a pretty seriously competent idiot, but I know they make industrisl trade idiots that put me to shame. I would not want to try to design and build something so complicated as a seastead and then let other people try to not break it.
If they sign a contract and end up with a cracked hull because they didn't do the thing they were supposed to do, that is not your fault.
