Re: "the ship from Momo"
It's a 1973 children's novel by Michael Ende about a girl of the same name, who ends up defeating time thieves (the so-called grey men). In one of the early scenes, Momo and her friends play out an adventure in an imaginary ship in an imaginary thunderstorm. And the ship is cast in a single piece. OK, it's outdated, but still quite well known where I live.
