If you read in the project page about its construction, it says that it is 'unsinkable!'
Alarm bells are ringing.
Also, if you zoom in on the pictures of it being built, the cranes used are made out of lego. You can see knobs you turn to make the mechanism work.
Also no mention is made about how to power the damn thing.
Merchant vessels need to be dry docked once a decade for a hull inspection, where would that happen?
I definitely think that this project is a scam.
